With the publication of this draft, the DOM Level 2 specification enters last call. The last call period will end on October 8, 1999. Comments on this document are invited and are to be sent to the public mailing list www-dom@w3.org. An archive is available at http://lists.w3.org/Archives/Public/www-dom/. Comments received during the last call period will be addressed by the Working Group which will then release an updated draft. Comments from implementors will then be awaited and will determine whether this specification can be submitted for Proposed Recommendation. While this document is in last call, it is still a draft document which may be updated, replaced or obsoleted by other documents at any time. It is therefore inappropriate to use it as reference material or to cite it as other than "work in progress". This is work in progress and does not imply endorsement by, or the consensus of, either W3C or members of the DOM Working Group. This document has been produced as part of the W3C DOM Activity. The authors of this document are the DOM WG members. Different modules of the Document Object Model have different editors. ------------------------------------------------------------------------ Abstract This specification defines the Document Object Model Level 2, a platform- and language-neutral interface that allows programs and scripts to dynamically access and update the content, structure and style of documents. The Document Object Model Level 2 builds on the Document Object Model Level 1. The DOM Level 2 is made of a set of core interfaces to create and manipulate the structure and contents of a document and a set of optional modules. These modules contain specialized interfaces dedicated to XML, HTML, an abstract view, generic stylesheets, Cascading Style Sheets, Events, traversing the document structure, and a Range object.

Editors Jonathan Robie, Software AG Introduction The Document Object Model (DOM) is an application programming interface (API) for HTML and XML documents. It defines the logical structure of documents and the way a document is accessed and manipulated. In the DOM specification, the term "document" is used in the broad sense - increasingly, XML is being used as a way of representing many different kinds of information that may be stored in diverse systems, and much of this would traditionally be seen as data rather than as documents. Nevertheless, XML presents this data as documents, and the DOM may be used to manage this data. With the Document Object Model, programmers can build documents, navigate their structure, and add, modify, or delete elements and content. Anything found in an HTML or XML document can be accessed, changed, deleted, or added using the Document Object Model, with a few exceptions - in particular, the DOM interfaces for the XML internal and external subsets have not yet been specified. As a W3C specification, one important objective for the Document Object Model is to provide a standard programming interface that can be used in a wide variety of environments and applications. The DOM is designed to be used with any programming language. In order to provide a precise, language-independent specification of the DOM interfaces, we have chosen to define the specifications in OMG IDL, as defined in the CORBA 2.2 specification [CORBA]. In addition to the OMG IDL specification, we provide language bindings for Java and ECMAScript (an industry-standard scripting language based on JavaScript and JScript) [Java] [ECMAScript]. Note: OMG IDL is used only as a language-independent and implementation-neutral way to specify interfaces. Various other IDLs could have been used. In general, IDLs are designed for specific computing environments. The Document Object Model can be implemented in any computing environment, and does not require the object binding runtimes generally associated with such IDLs. What the Document Object Model is The DOM is a programming API for documents. It is based on an object structure that closely resembles the structure of the documents it models. For instance, consider this table, taken from an HTML document:
Shady Grove Aeolian
Over the River, Charlie Dorian
The DOM represents this table like this: --------------------------------------------------------------------- [DOM representation of the example table] --------------------------------------------------------------------- DOM representation of the example table --------------------------------------------------------------------- In the DOM, documents have a logical structure which is very much like a tree; to be more precise, it is like a "forest" or "grove", which can contain more than one tree. Each document contains zero or one doctype nodes, one root element node, and zero or more comments or processing instructions; the root element serves as the root of the element tree for the document. However, the DOM does not specify that documents must be implemented as a tree or a grove, nor does it specify how the relationships among objects be implemented. The DOM is a logical model that may be implemented in any convenient manner. In this specification, we use the term structure model to describe the tree-like representation of a document; we specifically avoid terms like "tree" or "grove" in order to avoid implying a particular implementation. One important property of DOM structure models is structural isomorphism: if any two Document Object Model implementations are used to create a representation of the same document, they will create the same structure model, in accordance with the XML Information Set [Infoset]. The name "Document Object Model" was chosen because it is an "object model" in the traditional object oriented design sense: documents are modeled using objects, and the model encompasses not only the structure of a document, but also the behavior of a document and the objects of which it is composed. In other words, the nodes in the above diagram do not represent a data structure, they represent objects, which have functions and identity. As an object model, the DOM identifies: * the interfaces and objects used to represent and manipulate a document * the semantics of these interfaces and objects - including both behavior and attributes * the relationships and collaborations among these interfaces and objects The structure of SGML documents has traditionally been represented by an abstract data model, not by an object model. In an abstract data model, the model is centered around the data. In object oriented programming languages, the data itself is encapsulated in objects that hide the data, protecting it from direct external manipulation. The functions associated with these objects determine how the objects may be manipulated, and they are part of the object model. What the Document Object Model is not This section is designed to give a more precise understanding of the DOM by distinguishing it from other systems that may seem to be like it. * The Document Object Model is not a binary specification. DOM programs written in the same language will be source code compatible across platforms, but the DOM does not define any form of binary interoperability. * The Document Object Model is not a way of persisting objects to XML or HTML. Instead of specifying how objects may be represented in XML, the DOM specifies how XML and HTML documents are represented as objects, so that they may be used in object oriented programs. * The Document Object Model is not a set of data structures, it is an object model that specifies interfaces. Although this document contains diagrams showing parent/child relationships, these are logical relationships defined by the programming interfaces, not representations of any particular internal data structures. * The Document Object Model does not define what information in a document is relevant or how information in a document is structured. For XML, this is specified by the W3C XML Information Set [Infoset]. The DOM is simply an API to this information set. * The Document Object Model, despite its name, is not a competitor to the Component Object Model (COM). COM, like CORBA, is a language independent way to specify interfaces and objects; the DOM is a set of interfaces and objects designed for managing HTML and XML documents. The DOM may be implemented using language-independent systems like COM or CORBA; it may also be implemented using language-specific bindings like the Java or ECMAScript bindings specified in this document. Where the Document Object Model came from The DOM originated as a specification to allow JavaScript scripts and Java programs to be portable among Web browsers. "Dynamic HTML" was the immediate ancestor of the Document Object Model, and it was originally thought of largely in terms of browsers. However, when the DOM Working Group was formed at W3C, it was also joined by vendors in other domains, including HTML or XML editors and document repositories. Several of these vendors had worked with SGML before XML was developed; as a result, the DOM has been influenced by SGML Groves and the HyTime standard. Some of these vendors had also developed their own object models for documents in order to provide an API for SGML/XML editors or document repositories, and these object models have also influenced the DOM. Entities and the DOM Core In the fundamental DOM interfaces, there are no objects representing entities. Numeric character references, and references to the pre-defined entities in HTML and XML, are replaced by the single character that makes up the entity's replacement. For example, in:

This is a dog & a cat

the "&" will be replaced by the character "&", and the text in the P element will form a single continuous sequence of characters. Since numeric character references and pre-defined entities are not recognized as such in CDATA sections, or the SCRIPT and STYLE elements in HTML, they are not replaced by the single character they appear to refer to. If the example above were enclosed in a CDATA section, the "&" would not be replaced by "&"; neither would the

be recognized as a start tag. The representation of general entities, both internal and external, are defined within the extended (XML) interfaces of the Level 1 specification. Note: When a DOM representation of a document is serialized as XML or HTML text, applications will need to check each character in text data to see if it needs to be escaped using a numeric or pre-defined entity. Failing to do so could result in invalid HTML or XML. Also, implementations should be aware of the fact that serialization into a character encoding ("charset") that does not fully cover ISO 10646 may fail if there are characters in markup or CDATA sections that are not present in the encoding. Compliance The Document Object Model level 2 consists of several modules: Core, HTML, Views, StyleSheets, CSS, Events, Traversal, and Range. The DOM Core represents the functionality used for XML documents, and also serves as the basis for DOM HTML. A compliant implementation of the DOM must implement all of the fundamental interfaces in the Core chapter with the semantics as defined. Further, it must implement at least one of the HTML DOM and the extended (XML) interfaces with the semantics as defined. The other modules are optional. DOM Interfaces and DOM Implementations The DOM specifies interfaces which may be used to manage XML or HTML documents. It is important to realize that these interfaces are an abstraction - much like "abstract base classes" in C++, they are a means of specifying a way to access and manipulate an application's internal representation of a document. Interfaces do not imply a particular concrete implementation. Each DOM application is free to maintain documents in any convenient representation, as long as the interfaces shown in this specification are supported. Some DOM implementations will be existing programs that use the DOM interfaces to access software written long before the DOM specification existed. Therefore, the DOM is designed to avoid implementation dependencies; in particular, 1. Attributes defined in the IDL do not imply concrete objects which must have specific data members - in the language bindings, they are translated to a pair of get()/set() functions, not to a data member. Read-only attributes have only a get() function in the language bindings. 2. DOM applications may provide additional interfaces and objects not found in this specification and still be considered DOM compliant. 3. Because we specify interfaces and not the actual objects that are to be created, the DOM can not know what constructors to call for an implementation. In general, DOM users call the createXXX() methods on the Document class to create document structures, and DOM implementations create their own internal representations of these structures in their implementations of the createXXX() functions. 1. Document Object Model Core Editors Arnaud Le Hors, W3C Mike Champion, ArborText (for DOM Level 1 from November 20, 1997) Steve Byrne, JavaSoft (for DOM Level 1 until November 19, 1997) Gavin Nicol, Inso EPS (for DOM Level 1) Lauren Wood, SoftQuad, Inc. (for DOM Level 1) 1.1. Overview of the DOM Core Interfaces This section defines a minimal set of objects and interfaces for accessing and manipulating document objects. The functionality specified in this section (the Core functionality) is sufficient to allow software developers and web script authors to access and manipulate parsed HTML and XML content inside conforming products. The DOM Core API also allows creation and population of a Document object using only DOM API calls; loading a Document and saving it persistently is left to the product that implements the DOM API. 1.1.1. The DOM Structure Model The DOM presents documents as a hierarchy of Node objects that also implement other, more specialized interfaces. Some types of nodes may have child nodes of various types, and others are leaf nodes that cannot have anything below them in the document structure. The node types, and which node types they may have as children, are as follows: * Document -- Element (maximum of one), ProcessingInstruction, Comment, DocumentType * DocumentFragment -- Element, ProcessingInstruction, Comment, Text, CDATASection, EntityReference * DocumentType -- no children * EntityReference -- Element, ProcessingInstruction, Comment, Text, CDATASection, EntityReference * Element -- Element, Text, Comment, ProcessingInstruction, CDATASection, EntityReference * Attr -- Text, EntityReference * ProcessingInstruction -- no children * Comment -- no children * Text -- no children * CDATASection -- no children * Entity -- Element, ProcessingInstruction, Comment, Text, CDATASection, EntityReference * Notation -- no children The DOM also specifies a NodeList interface to handle ordered lists of Nodes, such as the children of a Node, or the elements returned by the getElementsByTagName method of the Element interface, and also a NamedNodeMap interface to handle unordered sets of nodes referenced by their name attribute, such as the attributes of an Element. NodeList and NamedNodeMap objects in the DOM are "live", that is, changes to the underlying document structure are reflected in all relevant NodeList and NamedNodeMap objects. For example, if a DOM user gets a NodeList object containing the children of an Element, then subsequently adds more children to that element (or removes children, or modifies them), those changes are automatically reflected in the NodeList, without further action on the user's part. Likewise, changes to a Node in the tree are reflected in all references to that Node in NodeList and NamedNodeMap objects. Finally, the interfaces Text, Comment, and CDATASection all inherit from the CharacterData interface. 1.1.2. Memory Management Most of the APIs defined by this specification are interfaces rather than classes. That means that an actual implementation need only expose methods with the defined names and specified operation, not actually implement classes that correspond directly to the interfaces. This allows the DOM APIs to be implemented as a thin veneer on top of legacy applications with their own data structures, or on top of newer applications with different class hierarchies. This also means that ordinary constructors (in the Java or C++ sense) cannot be used to create DOM objects, since the underlying objects to be constructed may have little relationship to the DOM interfaces. The conventional solution to this in object-oriented design is to define factory methods that create instances of objects that implement the various interfaces. Objects implementing some interface "X" are created by a "createX()" method on the Document interface; this is because all DOM objects live in the context of a specific Document. The DOM Level 2 API does not define a standard way to create DOMImplementation objects; actual DOM implementations must provide some proprietary way of bootstrapping these DOM interfaces, and then all other objects can be built from there. The Core DOM APIs are designed to be compatible with a wide range of languages, including both general-user scripting languages and the more challenging languages used mostly by professional programmers. Thus, the DOM APIs need to operate across a variety of memory management philosophies, from language platforms that do not expose memory management to the user at all, through those (notably Java) that provide explicit constructors but provide an automatic garbage collection mechanism to automatically reclaim unused memory, to those (especially C/C++) that generally require the programmer to explicitly allocate object memory, track where it is used, and explicitly free it for re-use. To ensure a consistent API across these platforms, the DOM does not address memory management issues at all, but instead leaves these for the implementation. Neither of the explicit language bindings devised by the DOM Working Group (for ECMAScript and Java) require any memory management methods, but DOM bindings for other languages (especially C or C++) may require such support. These extensions will be the responsibility of those adapting the DOM API to a specific language, not the DOM WG. 1.1.3. Naming Conventions While it would be nice to have attribute and method names that are short, informative, internally consistent, and familiar to users of similar APIs, the names also should not clash with the names in legacy APIs supported by DOM implementations. Furthermore, both OMG IDL and ECMAScript have significant limitations in their ability to disambiguate names from different namespaces that makes it difficult to avoid naming conflicts with short, familiar names. So, DOM names tend to be long and quite descriptive in order to be unique across all environments. The Working Group has also attempted to be internally consistent in its use of various terms, even though these may not be common distinctions in other APIs. For example, we use the method name "remove" when the method changes the structural model, and the method name "delete" when the method gets rid of something inside the structure model. The thing that is deleted is not returned. The thing that is removed may be returned, when it makes sense to return it. 1.1.4. Inheritance vs Flattened Views of the API The DOM Core APIs present two somewhat different sets of interfaces to an XML/HTML document; one presenting an "object oriented" approach with a hierarchy of inheritance, and a "simplified" view that allows all manipulation to be done via the Node interface without requiring casts (in Java and other C-like languages) or query interface calls in COM environments. These operations are fairly expensive in Java and COM, and the DOM may be used in performance-critical environments, so we allow significant functionality using just the Node interface. Because many other users will find the inheritance hierarchy easier to understand than the "everything is a Node" approach to the DOM, we also support the full higher-level interfaces for those who prefer a more object-oriented API. In practice, this means that there is a certain amount of redundancy in the API. The Working Group considers the "inheritance" approach the primary view of the API, and the full set of functionality on Node to be "extra" functionality that users may employ, but that does not eliminate the need for methods on other interfaces that an object-oriented analysis would dictate. (Of course, when the O-O analysis yields an attribute or method that is identical to one on the Node interface, we don't specify a completely redundant one). Thus, even though there is a generic nodeName attribute on the Node interface, there is still a tagName attribute on the Element interface; these two attributes must contain the same value, but the Working Group considers it worthwhile to support both, given the different constituencies the DOM API must satisfy. 1.1.5. The DOMString type To ensure interoperability, the DOM specifies the following: * Type Definition DOMString A DOMString is a sequence of 16-bit units. IDL Definition typedef sequence DOMString; * Applications must encode DOMString using UTF-16 (defined in Appendix C.3 of [UNICODE] and Amendment 1 of [ISO-10646]). The UTF-16 encoding was chosen because of its widespread industry practice. Please note that for both HTML and XML, the document character set (and therefore the notation of numeric character references) is based on UCS [ISO-10646]. A single numeric character reference in a source document may therefore in some cases correspond to two 16-bit units in a DOMString (a high surrogate and a low surrogate). Note: Even though the DOM defines the name of the string type to be DOMString, bindings may use different names. For, example for Java, DOMString is bound to the String type because it also uses UTF-16 as its encoding. Note: As of August 1998, the OMG IDL specification included a wstring type. However, that definition did not meet the interoperability criteria of the DOM API since it relied on encoding negotiation to decide the width of a character. 1.1.6. Case sensitivity in the DOM The DOM has many interfaces that imply string matching. HTML processors generally assume an uppercase (less often, lowercase) normalization of names for such things as elements, while XML is explicitly case sensitive. For the purposes of the DOM, string matching is performed purely by binary comparison of the 16-bit units of the DOMString. As such, the DOM assumes that any normalizations take place in the processor, before the DOM structures are built. This then raises the issue of exactly what normalizations occur. The W3C I18N working group is in the process of defining exactly which normalizations are necessary for applications implementing the DOM. 1.1.7. XML Namespaces The DOM Level 2 supports XML namespaces [Namespaces] by augmenting several interfaces of the DOM Level 1 Core to allow creating and manipulating elements and attributes associated to a namespace. As far as the DOM is concerned, special attributes used for declaring XML namespaces are still exposed and can be manipulated just like any other attribute. Moving a node within a document, using the DOM, in no case results in a change of its namespace prefix or namespace URI. Similarly, creating a node with a namespace prefix and namespace URI, or changing the namespace prefix of a node, does not result in any addition, removal, or modification of any special attributes for declaring the appropriate XML namespaces. Applications are therefore responsible for declaring every namespace in use when saving a document into XML. The new methods, such as createElementNS and createAttributeNS of the Document interface, are meant to be used by namespace aware applications. Simple applications that do not use namespaces can use the DOM Level 1 methods, such as createElement and createAttribute. Elements and attributes created in this way do not have any namespace prefix or namespace URI. 1.2. Fundamental Interfaces The interfaces within this section are considered fundamental, and must be fully implemented by all conforming implementations of the DOM, including all HTML DOM implementations, unless otherwise specified. Exception DOMException DOM operations only raise exceptions in "exceptional" circumstances, i.e., when an operation is impossible to perform (either for logical reasons, because data is lost, or because the implementation has become unstable). In general, DOM methods return specific error values in ordinary processing situation, such as out-of-bound errors when using NodeList. Implementations may raise other exceptions under other circumstances. For example, implementations may raise an implementation-dependent exception if a null argument is passed. Some languages and object systems do not support the concept of exceptions. For such systems, error conditions may be indicated using native error reporting mechanisms. For some bindings, for example, methods may return error codes similar to those listed in the corresponding method descriptions. IDL Definition exception DOMException { unsigned short code; }; // ExceptionCode const unsigned short INDEX_SIZE_ERR = 1; const unsigned short DOMSTRING_SIZE_ERR = 2; const unsigned short HIERARCHY_REQUEST_ERR = 3; const unsigned short WRONG_DOCUMENT_ERR = 4; const unsigned short INVALID_CHARACTER_ERR = 5; const unsigned short NO_DATA_ALLOWED_ERR = 6; const unsigned short NO_MODIFICATION_ALLOWED_ERR = 7; const unsigned short NOT_FOUND_ERR = 8; const unsigned short NOT_SUPPORTED_ERR = 9; const unsigned short INUSE_ATTRIBUTE_ERR = 10; Definition group ExceptionCode An integer indicating the type of error generated. Defined Constants INDEX_SIZE_ERR If index or size is negative, or greater than the allowed value DOMSTRING_SIZE_ERR If the specified range of text does not fit into a DOMString HIERARCHY_REQUEST_ERR If any node is inserted somewhere it doesn't belong If a node is used in a different WRONG_DOCUMENT_ERR document than the one that created it (that doesn't support it) INVALID_CHARACTER_ERR If an invalid character is specified, such as in a name. NO_DATA_ALLOWED_ERR If data is specified for a node which does not support data If an attempt is made to modify NO_MODIFICATION_ALLOWED_ERR an object where modifications are not allowed If an attempt was made to NOT_FOUND_ERR reference a node in a context where it does not exist If the implementation does not NOT_SUPPORTED_ERR support the type of object requested If an attempt is made to add an INUSE_ATTRIBUTE_ERR attribute that is already inuse elsewhere Interface DOMImplementation The DOMImplementation interface provides a number of methods for performing operations that are independent of any particular instance of the document object model. IDL Definition interface DOMImplementation { boolean hasFeature(in DOMString feature, in DOMString version); // Introduced in DOM Level 2: DocumentType createDocumentType(in DOMString qualifiedName, in DOMString publicID, in DOMString systemID); // Introduced in DOM Level 2: Document createDocument(in DOMString namespaceURI, in DOMString qualifiedName, in DocumentType doctype) raises(DOMException); }; Methods hasFeature Test if the DOM implementation implements a specific feature. Parameters DOMString feature The package name of the feature to test (case-insensitive). The legal values are defined throughout this specification. The DOM Level 2 includes "HTML", "XML", as well as the several others. DOMString version This is the version number of the package name to test. In Level 2, this is the string "2.0". If the version is not specified, supporting any version of the feature will cause the method to return true. Return Value boolean true if the feature is implemented in the specified version, false otherwise. No Exceptions createDocumentType introduced in DOM Level 2 Creates an empty DocumentType node. HTML-only DOM implementations do not need to implement this method. Parameters DOMString qualifiedName The qualified name of the document type to be created. DOMString publicID The document type public identifier. DOMString systemID The document type system identifier. Return Value DocumentType A new DocumentType node with Node.ownerDocument set to null. No Exceptions createDocument introduced in DOM Level 2 Creates an XML Document object of the specified type with its document element. HTML-only DOM implementations do not need to implement this method. Parameters DOMString namespaceURI The namespace URI of the document element to create, or null. DOMString qualifiedName The qualified name of the document element to be created. DocumentType doctype The type of document to be created or null. When doctype is not null, its Node.ownerDocument attribute is set to the document being created. Return Value Document A new Document object. Exceptions DOMException WRONG_DOCUMENT_ERR: Raised if doctype has already been used with a different document. Interface DocumentFragment DocumentFragment is a "lightweight" or "minimal" Document object. It is very common to want to be able to extract a portion of a document's tree or to create a new fragment of a document. Imagine implementing a user command like cut or rearranging a document by moving fragments around. It is desirable to have an object which can hold such fragments and it is quite natural to use a Node for this purpose. While it is true that a Document object could fulfill this role, a Document object can potentially be a heavyweight object, depending on the underlying implementation. What is really needed for this is a very lightweight object. DocumentFragment is such an object. Furthermore, various operations -- such as inserting nodes as children of another Node -- may take DocumentFragment objects as arguments; this results in all the child nodes of the DocumentFragment being moved to the child list of this node. The children of a DocumentFragment node are zero or more nodes representing the tops of any sub-trees defining the structure of the document. DocumentFragment nodes do not need to be well-formed XML documents (although they do need to follow the rules imposed upon well-formed XML parsed entities, which can have multiple top nodes). For example, a DocumentFragment might have only one child and that child node could be a Text node. Such a structure model represents neither an HTML document nor a well-formed XML document. When a DocumentFragment is inserted into a Document (or indeed any other Node that may take children) the children of the DocumentFragment and not the DocumentFragment itself are inserted into the Node. This makes the DocumentFragment very useful when the user wishes to create nodes that are siblings; the DocumentFragment acts as the parent of these nodes so that the user can use the standard methods from the Node interface, such as insertBefore and appendChild. IDL Definition interface DocumentFragment : Node { }; Interface Document The Document interface represents the entire HTML or XML document. Conceptually, it is the root of the document tree, and provides the primary access to the document's data. Since elements, text nodes, comments, processing instructions, etc. cannot exist outside the context of a Document, the Document interface also contains the factory methods needed to create these objects. The Node objects created have a ownerDocument attribute which associates them with the Document within whose context they were created. IDL Definition interface Document : Node { readonly attribute DocumentType doctype; readonly attribute DOMImplementation implementation; readonly attribute Element documentElement; Element createElement(in DOMString tagName) raises(DOMException); DocumentFragment createDocumentFragment(); Text createTextNode(in DOMString data); Comment createComment(in DOMString data); CDATASection createCDATASection(in DOMString data) raises(DOMException); ProcessingInstruction createProcessingInstruction(in DOMString target, in DOMString data) raises(DOMException); Attr createAttribute(in DOMString name) raises(DOMException); EntityReference createEntityReference(in DOMString name) raises(DOMException); NodeList getElementsByTagName(in DOMString tagname); // Introduced in DOM Level 2: Node importNode(in Node importedNode, in boolean deep) raises(DOMException); // Introduced in DOM Level 2: Element createElementNS(in DOMString namespaceURI, in DOMString qualifiedName) raises(DOMException); // Introduced in DOM Level 2: Attr createAttributeNS(in DOMString namespaceURI, in DOMString qualifiedName) raises(DOMException); // Introduced in DOM Level 2: NodeList getElementsByTagNameNS(in DOMString namespaceURI, in DOMString localName); }; Attributes doctype of type DocumentType, readonly The Document Type Declaration (see DocumentType) associated with this document. For HTML documents as well as XML documents without a document type declaration this returns null. The DOM Level 2 does not support editing the Document Type Declaration, therefore docType cannot be altered in any way, including through the use of methods, such as insertNode or removeNode, inherited from Node. implementation of type DOMImplementation, readonly The DOMImplementation object that handles this document. A DOM application may use objects from multiple implementations. documentElement of type Element, readonly This is a convenience attribute that allows direct access to the child node that is the root element of the document. For HTML documents, this is the element with the tagName "HTML". Methods createElement Creates an element of the type specified. Note that the instance returned implements the Element interface, so attributes can be specified directly on the returned object. In addition, if there are known attributes with default values, Attr nodes representing them are automatically created and attached to the element. To create an element with a qualified name and namespace URI, use the createElementNS method. Parameters DOMString tagName The name of the element type to instantiate. For XML, this is case-sensitive. For HTML, the tagName parameter may be provided in any case, but it must be mapped to the canonical uppercase form by the DOM implementation. Return Value Element A new Element object. Exceptions DOMException INVALID_CHARACTER_ERR: Raised if the specified name contains an invalid character. createDocumentFragment Creates an empty DocumentFragment object. Return Value DocumentFragment A new DocumentFragment. No Parameters No Exceptions createTextNode Creates a Text node given the specified string. Parameters DOMString data The data for the node. Return Value Text The new Text object. No Exceptions createComment Creates a Comment node given the specified string. Parameters DOMString data The data for the node. Return Value Comment The new Comment object. No Exceptions createCDATASection Creates a CDATASection node whose value is the specified string. Parameters DOMString data The data for the CDATASection contents. Return Value CDATASection The new CDATASection object. Exceptions DOMException NOT_SUPPORTED_ERR: Raised if this document is an HTML document. createProcessingInstruction Creates a ProcessingInstruction node given the specified name and data strings. Parameters DOMString target The target part of the processing instruction. DOMString data The data for the node. Return Value ProcessingInstruction The new ProcessingInstruction object. Exceptions DOMException INVALID_CHARACTER_ERR: Raised if an invalid character is specified. NOT_SUPPORTED_ERR: Raised if this document is an HTML document. createAttribute Creates an Attr of the given name. Note that the Attr instance can then be set on an Element using the setAttribute method. To create an attribute with a qualified name and namespace URI, use the createAttributeNS method. Parameters DOMString name The name of the attribute. Return Value Attr A new Attr object. Exceptions DOMException INVALID_CHARACTER_ERR: Raised if the specified name contains an invalid character. createEntityReference Creates an EntityReference object. Parameters DOMString name The name of the entity to reference. Return Value EntityReference The new EntityReference object. Exceptions DOMException INVALID_CHARACTER_ERR: Raised if the specified name contains an invalid character. NOT_SUPPORTED_ERR: Raised if this document is an HTML document. getElementsByTagName Returns a NodeList of all the Elements with a given tag name in the order in which they would be encountered in a preorder traversal of the Document tree. Parameters DOMString tagname The name of the tag to match on. The special value "*" matches all tags. Return Value NodeList A new NodeList object containing all the matched Elements. No Exceptions importNode introduced in DOM Level 2 Imports a node from another document to this document. The returned node has no parent (parentNode is null). The source node is not altered or removed from the original document; this method creates a new copy of the source node. For all nodes, importing a node creates a node object owned by the importing document, with attribute values identical to the source node's nodeName and nodeType, plus the attributes related to namespaces (prefix and namespaces URI). As in the cloneNode operation on a Node, the source node is not altered. Additional information is copied as appropriate to the nodeType, attempting to mirror the behavior expected if a fragment of XML or HTML source was copied from one document to another, recognizing that the two documents may have different DTDs in the XML case. The following list describes the specifics for every type of node. ELEMENT_NODE Specified attribute nodes of the source element are imported, and the generated Attr nodes are attached to the generated Element. Default attributes are not copied, though if the document being imported into defines default attributes for this element name, those are assigned. If importNode deep parameter was set to true, the descendants of the source element will be recursively imported and the resulting nodes reassembled to form the corresponding subtree. ATTRIBUTE_NODE The specified flag is set to true on the generated Attr. The descendants of the the source Attr are recursively imported and the resulting nodes reassembled to form the corresponding subtree. Note that the deep parameter does not apply to Attr nodes; they always carry their children with them when imported. TEXT_NODE, CDATA_SECTION_NODE, COMMENT_NODE These three types of nodes inheriting from CharacterData copy their data and length attributes from those of the source node. ENTITY_REFERENCE_NODE Only the EntityReference itself is copied, even if a deep import is requested, since the source and destination documents might have defined the entity differently. If the document being imported into provides a definition for this entity name, its value is assigned. ENTITY_NODE Entity nodes can be imported, however in the current release of the DOM the DocumentType is readonly. Ability to add these imported nodes to a DocumentType will be considered for addition to a future release of the DOM. On import, the publicID, systemID, and notationName attributes are copied. If a deep import is requested, the descendants of the the source Entity is recursively imported and the resulting nodes reassembled to form the corresponding subtree. PROCESSING_INSTRUCTION_NODE The imported node copies its target and data values from those of the source node. DOCUMENT_NODE Document nodes cannot be imported. DOCUMENT_TYPE_NODE DocumentType nodes cannot be imported. DOCUMENT_FRAGMENT_NODE If the deep option was set true, the descendants of the source element will be recursively imported and the resulting nodes reassembled to form the corresponding subtree. Otherwise, this simply generates an empty DocumentFragment. NOTATION_NODE Notation nodes be imported, however in the current release of the DOM the DocumentType is readonly. Ability to add these imported nodes to a DocumentType will be considered for addition to a future release of the DOM. On import, the publicID, and systemID attributes are copied. Note that the deep parameter does not apply to Notation nodes since they never have any children. Parameters Node importedNode The node to import. boolean deep If true, recursively import the subtree under the specified node; if false, import only the node itself, as explained above. This does not apply to Attr, EntityReference, and Notation nodes. Return Value Node The imported node that belongs to this Document. Exceptions DOMException NOT_SUPPORTED_ERR: Raised if the type of node being imported is not supported. createElementNS introduced in DOM Level 2 Creates an element of the given qualified name and namespace URI. HTML-only DOM implementations do not need to implement this method. Parameters DOMString namespaceURI The namespace URI of the element to create. When it is null or an empty string, this method behaves like createElement. DOMString qualifiedName The qualified name of the element type to instantiate. Return Value Element A new Element object with the following attributes: Attribute Value Node.nodeName qualifiedName Node.namespaceNamenamespaceURI Node.prefix prefix, extracted from qualifiedName, or null if there is no prefix Node.localName local name, extracted from qualifiedName Element.tagName qualifiedName Exceptions DOMException INVALID_CHARACTER_ERR: Raised if the specified name contains an invalid character. createAttributeNS introduced in DOM Level 2 Creates an attribute of the given qualified name and namespace URI. HTML-only DOM implementations do not need to implement this method. Parameters DOMString namespaceURI The namespace URI of the attribute to create. When it is null or an empty string, this method behaves like createAttribute. DOMString qualifiedName The qualified name of the attribute to instantiate. Return Value Attr A new Attr object with the following attributes: Attribute Value Node.nodeName qualifiedName Node.namespaceNamenamespaceURI Node.prefix prefix, extracted from qualifiedName, or null if there is no prefix Node.localName local name, extracted from qualifiedName Attr.name qualifiedName Exceptions DOMException INVALID_CHARACTER_ERR: Raised if the specified name contains an invalid character. getElementsByTagNameNS introduced in DOM Level 2 Returns a NodeList of all the Elements with a given local name and namespace URI in the order in which they would be encountered in a preorder traversal of the Document tree. Parameters DOMString namespaceURI The namespace URI of the elements to match on. The special value "*" matches all namespaces. When it is null or an empty string, this method behaves like getElementsByTagName. DOMString localName The local name of the elements to match on. The special value "*" matches all local names. Return Value NodeList A new NodeList object containing all the matched Elements. No Exceptions Interface Node The Node interface is the primary datatype for the entire Document Object Model. It represents a single node in the document tree. While all objects implementing the Node interface expose methods for dealing with children, not all objects implementing the Node interface may have children. For example, Text nodes may not have children, and adding children to such nodes results in a DOMException being raised. The attributes nodeName, nodeValue and attributes are included as a mechanism to get at node information without casting down to the specific derived interface. In cases where there is no obvious mapping of these attributes for a specific nodeType (e.g., nodeValue for an Element or attributes for a Comment), this returns null. Note that the specialized interfaces may contain additional and more convenient mechanisms to get and set the relevant information.

Defined Constants ELEMENT_NODE The node is a Element. ATTRIBUTE_NODE The node is an Attr. TEXT_NODE The node is a Text node. CDATA_SECTION_NODE The node is a CDATASection. ENTITY_REFERENCE_NODE The node is an EntityReference. ENTITY_NODE The node is an Entity. PROCESSING_INSTRUCTION_NODE The node is a ProcessingInstruction. COMMENT_NODE The node is a Comment. DOCUMENT_NODE The node is a Document. DOCUMENT_TYPE_NODE The node is a DocumentType. DOCUMENT_FRAGMENT_NODE The node is a DocumentFragment. NOTATION_NODE The node is a Notation. The values of nodeName, nodeValue, and attributes vary according to the node type as follows: nodeName nodeValue attributes Element tagName null NamedNodeMap Attr name of attribute value of null attribute Text #text content of null the text node CDATASection #cdata-section content of null the CDATA Section EntityReference name of entity null null referenced Entity entity name null null ProcessingInstructiontarget entire null content excluding the target Comment #comment content of null the comment Document #document null null DocumentType document type name null null DocumentFragment #document-fragment null null Notation notation name null null Attributes nodeName of type DOMString, readonly The name of this node, depending on its type; see the table above. nodeValue of type DOMString The value of this node, depending on its type; see the table above. When it is defined to be null, setting it has no effect. Exceptions on setting DOMException NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly. Exceptions on retrieval DOMException DOMSTRING_SIZE_ERR: Raised when it would return more characters than fit in a DOMString variable on the implementation platform. nodeType of type unsigned short, readonly A code representing the type of the underlying object, as defined above. parentNode of type Node, readonly The parent of this node. All nodes, except Attr, Document, DocumentFragment, Entity, and Notation may have a parent. However, if a node has just been created and not yet added to the tree, or if it has been removed from the tree, this is null. childNodes of type NodeList, readonly A NodeList that contains all children of this node. If there are no children, this is a NodeList containing no nodes. The content of the returned NodeList is "live" in the sense that, for instance, changes to the children of the node object that it was created from are immediately reflected in the nodes returned by the NodeList accessors; it is not a static snapshot of the content of the node. This is true for every NodeList, including the ones returned by the getElementsByTagName method. firstChild of type Node, readonly The first child of this node. If there is no such node, this returns null. lastChild of type Node, readonly The last child of this node. If there is no such node, this returns null. previousSibling of type Node, readonly The node immediately preceding this node. If there is no such node, this returns null. nextSibling of type Node, readonly The node immediately following this node. If there is no such node, this returns null. attributes of type NamedNodeMap, readonly A NamedNodeMap containing the attributes of this node (if it is an Element) or null otherwise. ownerDocument of type Document, readonly, modified in DOM Level 2 The Document object associated with this node. This is also the Document object used to create new nodes. When this node is a Document or a DocumentType, which is not used with any Document yet, this is null. namespaceURI of type DOMString, readonly, introduced in DOM Level 2 The namespace URI of this node, or null if it is unspecified. When this node is of any type other than ELEMENT_NODE and ATTRIBUTE_NODE, this is always null and setting it has no effect. This is not a computed value that is the result of a namespace lookup based on an examination of the namespace declarations in scope. It is merely the namespace URI given at creation time. For nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is null. prefix of type DOMString, introduced in DOM Level 2 The namespace prefix of this node, or null if it is unspecified. When this node is of any type other than ELEMENT_NODE and ATTRIBUTE_NODE this is always null and setting it has no effect. For nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is null. Note that setting this attribute changes the nodeName attribute, which holds the qualified name, as well as the tagName and name attributes of the Element and Attr interfaces, when applicable. Exceptions on setting DOMException INVALID_CHARACTER_ERR: Raised if the specified prefix contains an invalid character. localName of type DOMString, readonly, introduced in DOM Level 2 Returns the local part of the qualified name of this node. For nodes created with a DOM Level 1 method, such as createElement from the Document interface, and for nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE this is the same as the nodeName attribute. Methods insertBefore Inserts the node newChild before the existing child node refChild. If refChild is null, insert newChild at the end of the list of children. If newChild is a DocumentFragment object, all of its children are inserted, in the same order, before refChild. If the newChild is already in the tree, it is first removed. Parameters Node newChild The node to insert. Node refChild The reference node, i.e., the node before which the new node must be inserted. Return Value Node The node being inserted. Exceptions DOMException HIERARCHY_REQUEST_ERR: Raised if this node is of a type that does not allow children of the type of the newChild node, or if the node to insert is one of this node's ancestors. WRONG_DOCUMENT_ERR: Raised if newChild was created from a different document than the one that created this node. NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly. NOT_FOUND_ERR: Raised if refChild is not a child of this node. replaceChild Replaces the child node oldChild with newChild in the list of children, and returns the oldChild node. If the newChild is already in the tree, it is first removed. Parameters Node newChild The new node to put in the child list. Node oldChild The node being replaced in the list. Return Value Node The node replaced. Exceptions DOMException HIERARCHY_REQUEST_ERR: Raised if this node is of a type that does not allow children of the type of the newChild node, or it the node to put in is one of this node's ancestors. WRONG_DOCUMENT_ERR: Raised if newChild was created from a different document than the one that created this node. NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly. NOT_FOUND_ERR: Raised if oldChild is not a child of this node. removeChild Removes the child node indicated by oldChild from the list of children, and returns it. Parameters Node oldChild The node being removed. Return Value Node The node removed. Exceptions DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly. NOT_FOUND_ERR: Raised if oldChild is not a child of this node. appendChild Adds the node newChild to the end of the list of children of this node. If the newChild is already in the tree, it is first removed. Parameters Node newChild The node to add. If it is a DocumentFragment object, the entire contents of the document fragment are moved into the child list of this node Return Value Node The node added. Exceptions DOMException HIERARCHY_REQUEST_ERR: Raised if this node is of a type that does not allow children of the type of the newChild node, or if the node to append is one of this node's ancestors. WRONG_DOCUMENT_ERR: Raised if newChild was created from a different document than the one that created this node. NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly. hasChildNodes This is a convenience method to allow easy determination of whether a node has any children. Return Value boolean true if the node has any children, false if the node has no children. No Parameters No Exceptions cloneNode Returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes. The duplicate node has no parent (parentNode returns null.). Cloning an Element copies all attributes and their values, including those generated by the XML processor to represent defaulted attributes, but this method does not copy any text it contains unless it is a deep clone, since the text is contained in a child Text node. Cloning any other type of node simply returns a copy of this node. Parameters boolean deep If true, recursively clone the subtree under the specified node; if false, clone only the node itself (and its attributes, if it is an Element). Return Value Node The duplicate node. No Exceptions supports introduced in DOM Level 2 Tests whether the DOM implementation implements a specific feature and that feature is supported by this node. Parameters DOMString feature The package name of the feature to test. This is the same name as what can be passed to the method hasFeature on DOMImplementation. DOMString version This is the version number of the package name to test. In Level 2, version 1, this is the string "2.0". If the version is not specified, supporting any version of the feature will cause the method to return true. Return Value boolean Returns true if this node defines a subtree within which the specified feature is supported, false otherwise. No Exceptions Interface NodeList The NodeList interface provides the abstraction of an ordered collection of nodes, without defining or constraining how this collection is implemented. The items in the NodeList are accessible via an integral index, starting from 0. IDL Definition interface NodeList { Node item(in unsigned long index); readonly attribute unsigned long length; }; Attributes length of type unsigned long, readonly The number of nodes in the list. The range of valid child node indices is 0 to length-1 inclusive. Methods item Returns the indexth item in the collection. If index is greater than or equal to the number of nodes in the list, this returns null. Parameters unsigned long index Index into the collection. Return Value Node The node at the indexth position in the NodeList, or null if that is not a valid index. No Exceptions Interface NamedNodeMap Objects implementing the NamedNodeMap interface are used to represent collections of nodes that can be accessed by name. Note that NamedNodeMap does not inherit from NodeList; NamedNodeMaps are not maintained in any particular order. Objects contained in an object implementing NamedNodeMap may also be accessed by an ordinal index, but this is simply to allow convenient enumeration of the contents of a NamedNodeMap, and does not imply that the DOM specifies an order to these Nodes. IDL Definition interface NamedNodeMap { Node getNamedItem(in DOMString name); Node setNamedItem(in Node arg) raises(DOMException); Node removeNamedItem(in DOMString name) raises(DOMException); Node item(in unsigned long index); readonly attribute unsigned long length; // Introduced in DOM Level 2: Node getNamedItemNS(in DOMString namespaceURI, in DOMString localName); // Introduced in DOM Level 2: Node removeNamedItemNS(in DOMString namespaceURI, in DOMString name) raises(DOMException); }; Attributes length of type unsigned long, readonly The number of nodes in the map. The range of valid child node indices is 0 to length-1 inclusive. Methods getNamedItem Retrieves a node specified by name. Parameters DOMString name Name of a node to retrieve. Return Value Node A Node (of any type) with the specified name, or null if the specified name did not identify any node in the map. No Exceptions setNamedItem Adds a node using its nodeName attribute, which is the qualified name when applicable. As the nodeName attribute is used to derive the name which the node must be stored under, multiple nodes of certain types (those that have a "special" string value) cannot be stored as the names would clash. This is seen as preferable to allowing nodes to be aliased. Parameters Node arg A node to store in a named node map. The node will later be accessible using the value of the nodeName attribute of the node. If a node with that name is already present in the map, it is replaced by the new one. Return Value Node If the new Node replaces an existing node with the same name the previously existing Node is returned, otherwise null is returned. Exceptions DOMException WRONG_DOCUMENT_ERR: Raised if arg was created from a different document than the one that created the NamedNodeMap. NO_MODIFICATION_ALLOWED_ERR: Raised if this NamedNodeMap is readonly. INUSE_ATTRIBUTE_ERR: Raised if arg is an Attr that is already an attribute of another Element object. The DOM user must explicitly clone Attr nodes to re-use them in other elements. removeNamedItem Removes a node specified by name. Parameters DOMString name The name of a node to remove. When this NamedNodeMap contains the attributes attached to an element, as returned by the attributes attribute of the Node interface, if the removed attribute is known to have a default value, an attribute immediately appears containing the default value. Return Value Node The node removed from the map if a node with such a name exists. Exceptions DOMException NOT_FOUND_ERR: Raised if there is no node named name in the map. item Returns the indexth item in the map. If index is greater than or equal to the number of nodes in the map, this returns null. Parameters unsigned long index Index into the map. Return Value Node The node at the indexth position in the NamedNodeMap, or null if that is not a valid index. No Exceptions getNamedItemNS introduced in DOM Level 2 Retrieves a node specified by local name and namespace URI. HTML-only DOM implementations do not need to implement this method. Parameters DOMString namespaceURI The namespace URI of the node to retrieve. When it is null or an empty string, this method behaves like getNamedItem. DOMString localName The local name of the node to retrieve. Return Value Node A Node (of any type) with the specified name, or null if the specified name did not identify any node in the map. No Exceptions removeNamedItemNS introduced in DOM Level 2 Removes a node specified by local name and namespace URI. HTML-only DOM implementations do not need to implement this method. Parameters DOMString namespaceURI The namespace URI of the node to remove. When it is null or an empty string, this method behaves like removeNamedItem. DOMString name The local name of the node to remove. When this NamedNodeMap contains the attributes attached to an element, as returned by the attributes attribute of the Node interface, if the removed attribute is known to have a default value, an attribute immediately appears containing the default value. Return Value Node The node removed from the map if a node with such a local name and namespace URI exists. Exceptions DOMException NOT_FOUND_ERR: Raised if there is no node named name in the map. Interface CharacterData The CharacterData interface extends Node with a set of attributes and methods for accessing character data in the DOM. For clarity this set is defined here rather than on each object that uses these attributes and methods. No DOM objects correspond directly to CharacterData, though Text and others do inherit the interface from it. All offsets in this interface start from 0. IDL Definition interface CharacterData : Node { attribute DOMString data; // raises(DOMException) on setting // raises(DOMException) on retrieval readonly attribute unsigned long length; DOMString substringData(in unsigned long offset, in unsigned long count) raises(DOMException); void appendData(in DOMString arg) raises(DOMException); void insertData(in unsigned long offset, in DOMString arg) raises(DOMException); void deleteData(in unsigned long offset, in unsigned long count) raises(DOMException); void replaceData(in unsigned long offset, in unsigned long count, in DOMString arg) raises(DOMException); }; Attributes data of type DOMString The character data of the node that implements this interface. The DOM implementation may not put arbitrary limits on the amount of data that may be stored in a CharacterData node. However, implementation limits may mean that the entirety of a node's data may not fit into a single DOMString. In such cases, the user may call substringData to retrieve the data in appropriately sized pieces. Exceptions on setting DOMException NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly. Exceptions on retrieval DOMException DOMSTRING_SIZE_ERR: Raised when it would return more characters than fit in a DOMString variable on the implementation platform. length of type unsigned long, readonly The number of 16-bit units that are available through data and the substringData method below. This may have the value zero, i.e., CharacterData nodes may be empty. Methods substringData Extracts a range of data from the node. Parameters unsigned long offset Start offset of substring to extract. unsigned long count The number of 16-bit units to extract. Return Value DOMString The specified substring. If the sum of offset and count exceeds the length, then all 16-bit units to the end of the data are returned. Exceptions DOMException INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the number of 16-bit units in data, or if the specified count is negative. DOMSTRING_SIZE_ERR: Raised if the specified range of text does not fit into a DOMString. appendData Append the string to the end of the character data of the node. Upon success, data provides access to the concatenation of data and the DOMString specified. Parameters DOMString arg The DOMString to append. Exceptions DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly. No Return Value insertData Insert a string at the specified character offset. Parameters unsigned long offset The character offset at which to insert. DOMString arg The DOMString to insert. Exceptions DOMException INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the number of 16-bit units in data. NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly. No Return Value deleteData Remove a range of 16-bit units from the node. Upon success, data and length reflect the change. Parameters unsigned long offset The offset from which to start removing. unsigned long count The number of 16-bit units to delete. If the sum of offset and count exceeds length then all 16-bit units from offset to the end of the data are deleted. Exceptions DOMException INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the number of 16-bit units in data, or if the specified count is negative. NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly. No Return Value replaceData Replace the characters starting at the specified 16-bit unit offset with the specified string. Parameters unsigned long offset The offset from which to start replacing. unsigned long count The number of 16-bit units to replace. If the sum of offset and count exceeds length, then all 16-bit units to the end of the data are replaced (i.e., the effect is the same as a remove method call with the same range, followed by an append method invocation). DOMString arg The DOMString with which the range must be replaced. Exceptions DOMException INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the number of 16-bit units in data, or if the specified count is negative. NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly. No Return Value Interface Attr The Attr interface represents an attribute in an Element object. Typically the allowable values for the attribute are defined in a document type definition. Attr objects inherit the Node interface, but since they are not actually child nodes of the element they describe, the DOM does not consider them part of the document tree. Thus, the Node attributes parentNode, previousSibling, and nextSibling have a null value for Attr objects. The DOM takes the view that attributes are properties of elements rather than having a separate identity from the elements they are associated with; this should make it more efficient to implement such features as default attributes associated with all elements of a given type. Furthermore, Attr nodes may not be immediate children of a DocumentFragment. However, they can be associated with Element nodes contained within a DocumentFragment. In short, users and implementors of the DOM need to be aware that Attr nodes have some things in common with other objects inheriting the Node interface, but they also are quite distinct. The attribute's effective value is determined as follows: if this attribute has been explicitly assigned any value, that value is the attribute's effective value; otherwise, if there is a declaration for this attribute, and that declaration includes a default value, then that default value is the attribute's effective value; otherwise, the attribute does not exist on this element in the structure model until it has been explicitly added. Note that the nodeValue attribute on the Attr instance can also be used to retrieve the string version of the attribute's value(s). In XML, where the value of an attribute can contain entity references, the child nodes of the Attr node provide a representation in which entity references are not expanded. These child nodes may be either Text or EntityReference nodes. Because the attribute type may be unknown, there are no tokenized attribute values. IDL Definition interface Attr : Node { readonly attribute DOMString name; readonly attribute boolean specified; attribute DOMString value; // raises(DOMException) on setting // Introduced in DOM Level 2: readonly attribute Element ownerElement; }; Attributes name of type DOMString, readonly Returns the name of this attribute. specified of type boolean, readonly If this attribute was explicitly given a value in the original document, this is true; otherwise, it is false. Note that the implementation is in charge of this attribute, not the user. If the user changes the value of the attribute (even if it ends up having the same value as the default value) then the specified flag is automatically flipped to true. To re-specify the attribute as the default value from the DTD, the user must delete the attribute. The implementation will then make a new attribute available with specified set to false and the default value (if one exists). In summary: + If the attribute has an assigned value in the document then specified is true, and the value is the assigned value. + If the attribute has no assigned value in the document and has a default value in the DTD, then specified is false, and the value is the default value in the DTD. + If the attribute has no assigned value in the document and has a value of #IMPLIED in the DTD, then the attribute does not appear in the structure model of the document. value of type DOMString On retrieval, the value of the attribute is returned as a string. Character and general entity references are replaced with their values. On setting, this creates a Text node with the unparsed contents of the string. Exceptions on setting DOMException NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly. ownerElement of type Element, readonly, introduced in DOM Level 2 The Element node this attribute is attached to or null if this attribute is not in use. Interface Element By far the vast majority of objects (apart from text) that authors encounter when traversing a document are Element nodes. Assume the following XML document: When represented using DOM, the top node is a Document node containing an Element node for "elementExample" which contains two child Element nodes, one for "subelement1" and one for "subelement2". "subelement1" contains no child nodes. Elements may have attributes associated with them; since the Element interface inherits from Node, the generic Node interface attribute attributes may be used to retrieve the set of all attributes for an element. There are methods on the Element interface to retrieve either an Attr object by name or an attribute value by name. In XML, where an attribute value may contain entity references, an Attr object should be retrieved to examine the possibly fairly complex sub-tree representing the attribute value. On the other hand, in HTML, where all attributes have simple string values, methods to directly access an attribute value can safely be used as a convenience. IDL Definition interface Element : Node { readonly attribute DOMString tagName; DOMString getAttribute(in DOMString name); void setAttribute(in DOMString name, in DOMString value) raises(DOMException); void removeAttribute(in DOMString name) raises(DOMException); Attr getAttributeNode(in DOMString name); Attr setAttributeNode(in Attr newAttr) raises(DOMException); Attr removeAttributeNode(in Attr oldAttr) raises(DOMException); NodeList getElementsByTagName(in DOMString name); void normalize(); // Introduced in DOM Level 2: DOMString getAttributeNS(in DOMString namespaceURI, in DOMString localName); // Introduced in DOM Level 2: void setAttributeNS(in DOMString namespaceURI, in DOMString localName, in DOMString value) raises(DOMException); // Introduced in DOM Level 2: void removeAttributeNS(in DOMString namespacURI, in DOMString localName) raises(DOMException); // Introduced in DOM Level 2: Attr getAttributeNodeNS(in DOMString namespaceURI, in DOMString localName); // Introduced in DOM Level 2: Attr setAttributeNodeNS(in Attr newAttr) raises(DOMException); // Introduced in DOM Level 2: NodeList getElementsByTagNameNS(in DOMString namespaceURI, in DOMString localName); }; Attributes tagName of type DOMString, readonly The name of the element. For example, in: ... , tagName has the value "elementExample". Note that this is case-preserving in XML, as are all of the operations of the DOM. The HTML DOM returns the tagName of an HTML element in the canonical uppercase form, regardless of the case in the source HTML document. Methods getAttribute Retrieves an attribute value by name. Parameters DOMString name The name of the attribute to retrieve. Return Value DOMString The Attr value as a string, or the empty string if that attribute does not have a specified or default value. No Exceptions setAttribute Adds a new attribute. If an attribute with that name is already present in the element, its value is changed to be that of the value parameter. This value is a simple string, it is not parsed as it is being set. So any markup (such as syntax to be recognized as an entity reference) is treated as literal text, and needs to be appropriately escaped by the implementation when it is written out. In order to assign an attribute value that contains entity references, the user must create an Attr node plus any Text and EntityReference nodes, build the appropriate subtree, and use setAttributeNode to assign it as the value of an attribute. Parameters DOMString name The name of the attribute to create or alter. DOMString value Value to set in string form. Exceptions DOMException INVALID_CHARACTER_ERR: Raised if the specified name contains an invalid character. NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly. No Return Value removeAttribute Removes an attribute by name. If the removed attribute is known to have a default value, an attribute immediately appears containing the default value. Parameters DOMString name The name of the attribute to remove. Exceptions DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly. No Return Value getAttributeNode Retrieves an Attr node by name. Parameters DOMString name The name of the attribute to retrieve. Return Value Attr The Attr node with the specified attribute name or null if there is no such attribute. No Exceptions setAttributeNode Adds a new attribute. If an attribute with that name is already present in the element, it is replaced by the new one. Parameters Attr newAttr The Attr node to add to the attribute list. Return Value Attr If the newAttr attribute replaces an existing attribute with the same name, the previously existing Attr node is returned, otherwise null is returned. Exceptions DOMException WRONG_DOCUMENT_ERR: Raised if newAttr was created from a different document than the one that created the element. NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly. INUSE_ATTRIBUTE_ERR: Raised if newAttr is already an attribute of another Element object. The DOM user must explicitly clone Attr nodes to re-use them in other elements. removeAttributeNode Removes the specified attribute. Parameters Attr oldAttr The Attr node to remove from the attribute list. If the removed Attr has a default value it is immediately replaced. Return Value Attr The Attr node that was removed. Exceptions DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly. NOT_FOUND_ERR: Raised if oldAttr is not an attribute of the element. getElementsByTagName Returns a NodeList of all descendant elements with a given tag name, in the order in which they would be encountered in a preorder traversal of the Element tree. Parameters DOMString name The name of the tag to match on. The special value "*" matches all tags. Return Value NodeList A list of matching Element nodes. No Exceptions normalize Puts all Text nodes in the full depth of the sub-tree underneath this Element into a "normal" form where only markup (e.g., tags, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are no adjacent Text nodes. This can be used to ensure that the DOM view of a document is the same as if it were saved and re-loaded, and is useful when operations (such as XPointer lookups) that depend on a particular document tree structure are to be used. No Parameters No Return Value No Exceptions getAttributeNS introduced in DOM Level 2 Retrieves an attribute value by local name and namespace URI. HTML-only DOM implementations do not need to implement this method. Parameters DOMString namespaceURI The namespace URI of the attribute to retrieve. When it is null or an empty string, this method behaves like getAttribute. DOMString localName The local name of the attribute to retrieve. Return Value DOMString The Attr value as a string, or an empty string if that attribute does not have a specified or default value. No Exceptions setAttributeNS introduced in DOM Level 2 Adds a new attribute. If an attribute with that local name and namespace URI is already present in the element, its value is changed to be that of the value parameter. This value is a simple string, it is not parsed as it is being set. So any markup (such as syntax to be recognized as an entity reference) is treated as literal text, and needs to be appropriately escaped by the implementation when it is written out. In order to assign an attribute value that contains entity references, the user must create an Attr node plus any Text and EntityReference nodes, build the appropriate subtree, and use setAttributeNodeNS or setAttributeNode to assign it as the value of an attribute. HTML-only DOM implementations do not need to implement this method. Parameters DOMString namespaceURI The namespace URI of the attribute to create or alter. When it is null or an empty string, this method behaves like getAttribute. DOMString localName The local name of the attribute to create or alter. DOMString value The value to set in string form. Exceptions DOMException INVALID_CHARACTER_ERR: Raised if the specified name contains an invalid character. NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly. No Return Value removeAttributeNS introduced in DOM Level 2 Removes an attribute by local name and namespace URI. If the removed attribute has a default value it is immediately replaced. HTML-only DOM implementations do not need to implement this method. Parameters DOMString namespacURI The namespace URI of the attribute to remove. When it is null or an empty string, this method behaves like removeAttribute. DOMString localName The local name of the attribute to remove. Exceptions DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly. No Return Value getAttributeNodeNS introduced in DOM Level 2 Retrieves an Attr node by local name and namespace URI. HTML-only DOM implementations do not need to implement this method. Parameters DOMString namespaceURI The namespace URI of the attribute to retrieve. When it is null or an empty string, this method behaves like getAttributeNode. DOMString localName The local name of the attribute to retrieve. Return Value Attr The Attr node with the specified attribute local name and namespace URI or null if there is no such attribute. No Exceptions setAttributeNodeNS introduced in DOM Level 2 Adds a new attribute. If an attribute with that local name and namespace URI is already present in the element, it is replaced by the new one. HTML-only DOM implementations do not need to implement this method. Parameters Attr newAttr The Attr node to add to the attribute list. When the node has no namespaceURI, this method behaves like setAttributeNode. Return Value Attr If the newAttr attribute replaces an existing attribute with the same local name and namespace URI, the previously existing Attr node is returned, otherwise null is returned. Exceptions DOMException WRONG_DOCUMENT_ERR: Raised if newAttr was created from a different document than the one that created the element. NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly. INUSE_ATTRIBUTE_ERR: Raised if newAttr is already an attribute of another ElementNS object. The DOM user must explicitly clone Attr nodes to re-use them in other elements. getElementsByTagNameNS introduced in DOM Level 2 Returns a NodeList of all the Elements with a given local name and namespace URI in the order in which they would be encountered in a preorder traversal of the Document tree, starting from this node. HTML-only DOM implementations do not need to implement this method. Parameters DOMString namespaceURI The namespace URI of the elements to match on. The special value "*" matches all namespaces. When it is null or an empty string, this method behaves like getElementsByTagName. DOMString localName The local name of the elements to match on. The special value "*" matches all local names. Return Value NodeList A new NodeList object containing all the matched Elements. No Exceptions Interface Text The Text interface inherits from CharacterData and represents the textual content (termed character data in XML) of an Element or Attr. If there is no markup inside an element's content, the text is contained in a single object implementing the Text interface that is the only child of the element. If there is markup, it is parsed into a list of elements and Text nodes that form the list of children of the element. When a document is first made available via the DOM, there is only one Text node for each block of text. Users may create adjacent Text nodes that represent the contents of a given element without any intervening markup, but should be aware that there is no way to represent the separations between these nodes in XML or HTML, so they will not (in general) persist between DOM editing sessions. The normalize() method on Element merges any such adjacent Text objects into a single node for each block of text; this is recommended before employing operations that depend on a particular document structure, such as navigation with XPointers. IDL Definition interface Text : CharacterData { Text splitText(in unsigned long offset) raises(DOMException); }; Methods splitText Breaks this Text node into two Text nodes at the specified offset, keeping both in the tree as siblings. This node then only contains all the content up to the offset point. And a new Text node, which is inserted as the next sibling of this node, contains all the content at and after the offset point. Parameters unsigned long offset The 16-bit unit offset at which to split, starting from 0. Return Value Text The new Text node. Exceptions DOMException INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the number of 16-bit units in data. NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly. Interface Comment This interface inherits from CharacterData and represents the content of a comment, i.e., all the characters between the starting ''. Note that this is the definition of a comment in XML, and, in practice, HTML, although some HTML tools may implement the full SGML comment structure. IDL Definition interface Comment : CharacterData { }; 1.3. Extended Interfaces The interfaces defined here form part of the DOM Core specification, but objects that expose these interfaces will never be encountered in a DOM implementation that deals only with HTML. As such, HTML-only DOM implementations do not need to have objects that implement these interfaces. A DOM application can use the hasFeature method of the DOMImplementation interface to determine whether they are supported or not. The feature string for all the interfaces listed in this section is "XML". Interface CDATASection CDATA sections are used to escape blocks of text containing characters that would otherwise be regarded as markup. The only delimiter that is recognized in a CDATA section is the "]]>" string that ends the CDATA section. CDATA sections can not be nested. The primary purpose is for including material such as XML fragments, without needing to escape all the delimiters. The DOMString attribute of the Text node holds the text that is contained by the CDATA section. Note that this may contain characters that need to be escaped outside of CDATA sections and that, depending on the character encoding ("charset") chosen for serialization, it may be impossible to write out some characters as part of a CDATA section. The CDATASection interface inherits from the CharacterData interface through the Text interface. Adjacent CDATASections nodes are not merged by use of the normalize method of the Element interface. IDL Definition interface CDATASection : Text { }; Interface DocumentType Each Document has a doctype attribute whose value is either null or a DocumentType object. The DocumentType interface in the DOM Core provides an interface to the list of entities that are defined for the document, and little else because the effect of namespaces and the various XML scheme efforts on DTD representation are not clearly understood as of this writing. The DOM Level 2 doesn't support editing DocumentType nodes. IDL Definition interface DocumentType : Node { readonly attribute DOMString name; readonly attribute NamedNodeMap entities; readonly attribute NamedNodeMap notations; // Introduced in DOM Level 2: readonly attribute DOMString publicID; // Introduced in DOM Level 2: readonly attribute DOMString systemID; }; Attributes name of type DOMString, readonly The name of DTD; i.e., the name immediately following the DOCTYPE keyword. entities of type NamedNodeMap, readonly A NamedNodeMap containing the general entities, both external and internal, declared in the DTD. Duplicates are discarded. For example in: ]> the interface provides access to foo and bar but not baz. Every node in this map also implements the Entity interface. The DOM Level 2 does not support editing entities, therefore entities cannot be altered in any way. notations of type NamedNodeMap, readonly A NamedNodeMap containing the notations declared in the DTD. Duplicates are discarded. Every node in this map also implements the Notation interface. The DOM Level 2 does not support editing notations, therefore notations cannot be altered in any way. publicID of type DOMString, readonly, introduced in DOM Level 2 The public identifier of this document type. systemID of type DOMString, readonly, introduced in DOM Level 2 The system identifier of this document type. Interface Notation This interface represents a notation declared in the DTD. A notation either declares, by name, the format of an unparsed entity (see section 4.7 of the XML 1.0 specification), or is used for formal declaration of Processing Instruction targets (see section 2.6 of the XML 1.0 specification). The nodeName attribute inherited from Node is set to the declared name of the notation. The DOM Level 1 does not support editing Notation nodes; they are therefore readonly. A Notation node does not have any parent. IDL Definition interface Notation : Node { readonly attribute DOMString publicId; readonly attribute DOMString systemId; }; Attributes publicId of type DOMString, readonly The public identifier of this notation. If the public identifier was not specified, this is null. systemId of type DOMString, readonly The system identifier of this notation. If the system identifier was not specified, this is null. Interface Entity This interface represents an entity, either parsed or unparsed, in an XML document. Note that this models the entity itself not the entity declaration. Entity declaration modeling has been left for a later Level of the DOM specification. The nodeName attribute that is inherited from Node contains the name of the entity. An XML processor may choose to completely expand entities before the structure model is passed to the DOM; in this case there will be no EntityReference nodes in the document tree. XML does not mandate that a non-validating XML processor read and process entity declarations made in the external subset or declared in external parameter entities. This means that parsed entities declared in the external subset need not be expanded by some classes of applications, and that the replacement value of the entity may not be available. When the replacement value is available, the corresponding Entity node's child list represents the structure of that replacement text. Otherwise, the child list is empty. The resolution of the children of the Entity (the replacement value) may be lazily evaluated; actions by the user (such as calling the childNodes method on the Entity Node) are assumed to trigger the evaluation. The DOM Level 2 does not support editing Entity nodes; if a user wants to make changes to the contents of an Entity, every related EntityReference node has to be replaced in the structure model by a clone of the Entity's contents, and then the desired changes must be made to each of those clones instead. All the descendants of an Entity node are readonly. An Entity node does not have any parent. IDL Definition interface Entity : Node { readonly attribute DOMString publicId; readonly attribute DOMString systemId; readonly attribute DOMString notationName; }; Attributes publicId of type DOMString, readonly The public identifier associated with the entity, if specified. If the public identifier was not specified, this is null. systemId of type DOMString, readonly The system identifier associated with the entity, if specified. If the system identifier was not specified, this is null. notationName of type DOMString, readonly For unparsed entities, the name of the notation for the entity. For parsed entities, this is null. Interface EntityReference EntityReference objects may be inserted into the structure model when an entity reference is in the source document, or when the user wishes to insert an entity reference. Note that character references and references to predefined entities are considered to be expanded by the HTML or XML processor so that characters are represented by their Unicode equivalent rather than by an entity reference. Moreover, the XML processor may completely expand references to entities while building the structure model, instead of providing EntityReference objects. If it does provide such objects, then for a given EntityReference node, it may be that there is no Entity node representing the referenced entity; but if such an Entity exists, then the child list of the EntityReference node is the same as that of the Entity node. As with the Entity node, all descendants of the EntityReference are readonly. The resolution of the children of the EntityReference (the replacement value of the referenced Entity) may be lazily evaluated; actions by the user (such as calling the childNodes method on the EntityReference node) are assumed to trigger the evaluation. IDL Definition interface EntityReference : Node { }; Interface ProcessingInstruction The ProcessingInstruction interface represents a "processing instruction", used in XML as a way to keep processor-specific information in the text of the document. IDL Definition interface ProcessingInstruction : Node { readonly attribute DOMString target; attribute DOMString data; // raises(DOMException) on setting }; Attributes target of type DOMString, readonly The target of this processing instruction. XML defines this as being the first token following the markup that begins the processing instruction. data of type DOMString The content of this processing instruction. This is from the first non white space character after the target to the character immediately preceding the ?>. Exceptions on setting DOMException NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly. 2. Document Object Model HTML Editors Arnaud Le Hors, W3C Mike Champion, ArborText (for DOM Level 1) Vidur Apparao, Netscape (for DOM Level 1) Scott Isaacs, Microsoft (for DOM Level 1 until January 1998) Chris Wilson, Microsoft (for DOM Level 1 after January 1998) Ian Jacobs, W3C (for DOM Level 1) 2.1. Introduction This section extends the Core API to describe objects and methods specific to HTML documents. In general, the functionality needed to manipulate hierarchical document structures, elements, and attributes will be found in the core section; functionality that depends on the specific elements defined in HTML will be found in this section. The goals of the HTML-specific DOM API are: * to specialize and add functionality that relates specifically to HTML documents and elements. * to address issues of backwards compatibility with the DOM Level 0. * to provide convenience mechanisms, where appropriate, for common and frequent operations on HTML documents. The key differences between the core DOM and the HTML application of DOM is that the HTML Document Object Model exposes a number of convenience methods and properties that are consistent with the existing models and are more appropriate to script writers. In many cases, these enhancements are not applicable to a general DOM because they rely on the presence of a predefined DTD. The transitional and frameset DTDs for HTML 4.0 are assumed. Interoperability between implementations is only guaranteed for elements and attributes that are specified in these DTDs. More specifically, this document includes the following specializations for HTML: * An HTMLDocument interface, derived from the core Document interface. HTMLDocument specifies the operations and queries that can be made on a HTML document. * An HTMLElement interface, derived from the core Element interface. HTMLElement specifies the operations and queries that can be made on any HTML element. Methods on HTMLElement include those that allow for the retrieval and modification of attributes that apply to all HTML elements. * Specializations for all HTML elements that have attributes that extend beyond those specified in the HTMLElement interface. For all such attributes, the derived interface for the element contains explicit methods for setting and getting the values. The DOM Level 2 includes mechanisms to access and modify style specified through CSS and defines an event model that can be used with HTML documents. The interfaces found within this section are not mandatory. A DOM application can use the hasFeature method of the DOMImplementation interface to determine whether they are supported or not. The feature string for all the interfaces listed in this section is "HTML". 2.2. HTML Application of Core DOM 2.2.1. Naming Conventions The HTML DOM follows a naming convention for properties, methods, events, collections, and data types. All names are defined as one or more English words concatenated together to form a single string. 2.2.1.1. Properties and Methods The property or method name starts with the initial keyword in lowercase, and each subsequent word starts with a capital letter. For example, a property that returns document meta information such as the date the file was created might be named "fileDateCreated". In the ECMAScript binding, properties are exposed as properties of a given object. In Java, properties are exposed with get and set methods. 2.2.1.2. Non-HTML 4.0 interfaces and attributes While most of the interfaces defined below can be mapped directly to elements defined in the HTML 4.0 Recommendation, some of them cannot. Similarly, not all attributes listed below have counterparts in the HTML 4.0 specification (and some do, but have been renamed to avoid conflicts with scripting languages). Interfaces and attribute definitions that have links to the HTML 4.0 specification have corresponding element and attribute definitions there; all others are added by this specification, either for convenience or backwards compatibility with DOM Level 0 implementations. 2.3. Miscellaneous Object Definitions Interface HTMLDOMImplementation (introduced in DOM Level 2) The HTMLDOMImplementation interface extends the DOMImplementation interface with a method for creating an HTML document instance. IDL Definition // Introduced in DOM Level 2: interface HTMLDOMImplementation : DOMImplementation { HTMLDocument createHTMLDocument(in DOMString title); }; Methods createHTMLDocument Creates an HTMLDocument object with the minimal tree made of the following elements: HTML, HEAD, TITLE, and BODY. Parameters DOMString title The title of the document to be set as the content of the TITLE element, through a child Text node. Return Value HTMLDocument A new HTMLDocument object. No Exceptions Interface HTMLCollection An HTMLCollection is a list of nodes. An individual node may be accessed by either ordinal index or the node's name or id attributes. Note: Collections in the HTML DOM are assumed to be live meaning that they are automatically updated when the underlying document is changed. IDL Definition interface HTMLCollection { readonly attribute unsigned long length; Node item(in unsigned long index); Node namedItem(in DOMString name); }; Attributes length of type unsigned long, readonly This attribute specifies the length or size of the list. Methods item This method retrieves a node specified by ordinal index. Nodes are numbered in tree order (depth-first traversal order). Parameters unsigned long index The index of the node to be fetched. The index origin is 0. Return Value Node The Node at the corresponding position upon success. A value of null is returned if the index is out of range. No Exceptions namedItem This method retrieves a Node using a name. It first searches for a Node with a matching id attribute. If it doesn't find one, it then searches for a Node with a matching name attribute, but only on those elements that are allowed a name attribute. Parameters DOMString name The name of the Node to be fetched. Return Value Node The Node with a name or id attribute whose value corresponds to the specified string. Upon failure (e.g., no node with this name exists), returns null. No Exceptions 2.4. Objects related to HTML documents Interface HTMLDocument An HTMLDocument is the root of the HTML hierarchy and holds the entire content. Beside providing access to the hierarchy, it also provides some convenience methods for accessing certain sets of information from the document. The following properties have been deprecated in favor of the corresponding ones for the BODY element: o alinkColor o background o bgColor o fgColor o linkColor o vlinkColor IDL Definition interface HTMLDocument : Document { attribute DOMString title; readonly attribute DOMString referrer; readonly attribute DOMString domain; readonly attribute DOMString URL; attribute HTMLElement body; readonly attribute HTMLCollection images; readonly attribute HTMLCollection applets; readonly attribute HTMLCollection links; readonly attribute HTMLCollection forms; readonly attribute HTMLCollection anchors; attribute DOMString cookie; void open(); void close(); void write(in DOMString text); void writeln(in DOMString text); Element getElementById(in DOMString elementId); NodeList getElementsByName(in DOMString elementName); }; Attributes title of type DOMString The title of a document as specified by the TITLE element in the head of the document. referrer of type DOMString, readonly Returns the URI of the page that linked to this page. The value is an empty string if the user navigated to the page directly (not through a link, but, for example, via a bookmark). domain of type DOMString, readonly The domain name of the server that served the document, or null if the server cannot be identified by a domain name. URL of type DOMString, readonly The complete URI of the document. body of type HTMLElement The element that contains the content for the document. In documents with BODY contents, returns the BODY element, and in frameset documents, this returns the outermost FRAMESET element. images of type HTMLCollection, readonly A collection of all the IMG elements in a document. The behavior is limited to IMG elements for backwards compatibility. applets of type HTMLCollection, readonly A collection of all the OBJECT elements that include applets and APPLET (deprecated) elements in a document. links of type HTMLCollection, readonly A collection of all AREA elements and anchor (A) elements in a document with a value for the href attribute. forms of type HTMLCollection, readonly A collection of all the forms of a document. anchors of type HTMLCollection, readonly A collection of all the anchor (A) elements in a document with a value for the name attribute.Note. For reasons of backwards compatibility, the returned set of anchors only contains those anchors created with the name attribute, not those created with the id attribute. cookie of type DOMString The cookies associated with this document. If there are none, the value is an empty string. Otherwise, the value is a string: a semicolon-delimited list of "name, value" pairs for all the cookies associated with the page. For example, name=value;expires=date. Methods open Note. This method and the ones following allow a user to add to or replace the structure model of a document using strings of unparsed HTML. At the time of writing alternate methods for providing similar functionality for both HTML and XML documents were being considered. The following methods may be deprecated at some point in the future in favor of a more general-purpose mechanism. Open a document stream for writing. If a document exists in the target, this method clears it. No Parameters No Return Value No Exceptions close Closes a document stream opened by open() and forces rendering. No Parameters No Return Value No Exceptions write Write a string of text to a document stream opened by open(). The text is parsed into the document's structure model. Parameters DOMString text The string to be parsed into some structure in the document structure model. No Return Value No Exceptions writeln Write a string of text followed by a newline character to a document stream opened by open(). The text is parsed into the document's structure model. Parameters DOMString text The string to be parsed into some structure in the document structure model. No Return Value No Exceptions getElementById Returns the Element whose id is given by elementId. If no such element exists, returns null. Behavior is not defined if more than one element has this id. Parameters DOMString elementId The unique id value for an element. Return Value Element The matching element. No Exceptions getElementsByName Returns the (possibly empty) collection of elements whose name value is given by elementName. Parameters DOMString elementName The name attribute value for an element. Return Value NodeList The matching elements. No Exceptions 2.5. HTML Elements 2.5.1. Property Attributes HTML attributes are exposed as properties on the element object. The name of the exposed property always uses the naming conventions, and is independent of the case of the attribute in the source document. The data type of the property is determined by the type of the attribute as determined by the HTML 4.0 transitional and frameset DTDs. The attributes have the semantics (including case-sensitivity) given in the HTML 4.0 specification. The attributes are exposed as properties for compatibility with DOM Level 0. This usage is deprecated because it can not be generalized to all possible attribute names, as is required both for XML and potentially for future versions of HTML. We recommend the use of generic methods on the core Element interface for setting, getting and removing attributes. DTD Data Type Object Model Data Type CDATA DOMString Value list (e.g., (left | right | center))DOMString one-value Value list (e.g., (border)) boolean Number long int The return value of an attribute that has a data type that is a value list is always capitalized, independent of the case of the value in the source document. For example, if the value of the align attribute on a P element is "left" then it is returned as "Left". For attributes with the CDATA data type, the case of the return value is that given in the source document. 2.5.2. Naming Exceptions To avoid name-space conflicts, an attribute with the same name as a keyword in one of our chosen binding languages is prefixed. For HTML, the prefix used is "html". For example, the for attribute of the LABEL element collides with loop construct naming conventions and is renamed htmlFor. 2.5.3. Exposing Element Type Names (tagName) The element type names exposed through a property are in uppercase. For example, the body element type name is exposed through the "tagName" property as "BODY". 2.5.4. The HTMLElement interface Interface HTMLElement All HTML element interfaces derive from this class. Elements that only expose the HTML core attributes are represented by the base HTMLElement interface. These elements are as follows: o HEAD o special: SUB, SUP, SPAN, BDO o font: TT, I, B, U, S, STRIKE, BIG, SMALL o phrase: EM, STRONG, DFN, CODE, SAMP, KBD, VAR, CITE, ACRONYM, ABBR o list: DD, DT o NOFRAMES, NOSCRIPT o ADDRESS, CENTER Note. The style attribute for this interface is part of the Document Object Model CSS. See the HTMLElementCSS interface. IDL Definition interface HTMLElement : Element { attribute DOMString id; attribute DOMString title; attribute DOMString lang; attribute DOMString dir; attribute DOMString className; }; Attributes id of type DOMString The element's identifier.

Document Object Model Views Editors Laurence Cable, Sun Arnaud Le Hors, W3C 3.1. Introduction A document may have one or more "views" associated with it, e.g: a computed view on a document after applying a CSS stylesheet, or multiple presentations (e.g HTML Frame) of the same document in a client. This section defines an AbstractView interface which provides a base interface that all such views shall derive from. It defines an attribute which references the target document. In the DOM Level 2, there are no subinterfaces of AbstractView defined, it is introduced for use in future revisions. However, AbstractView is defined in this version to provide a distinguishing attribute; of a Document as a "default" (implementation dependent) view thereof, and of a UIEvent to identify the (implementation dependent) origin of the screenX and screenY attributes therein. The interfaces found within this section are not mandatory. A DOM application can use the hasFeature method of the DOMImplementation interface to determine whether they are supported or not. The feature string for all the interfaces listed in this section is "Views". 3.2. Interfaces Interface AbstractView (introduced in DOM Level 2) A base interface that all views shall derive from. IDL Definition // Introduced in DOM Level 2: interface AbstractView { readonly attribute DocumentView document; }; Attributes document of type DocumentView, readonly The source DocumentView for which, this is an AbstractView of. Interface DocumentView (introduced in DOM Level 2) The DocumentView interface is implemented by Document objects in DOM implementations supporting DOM Views. It provides an attribute to retrieve the default view of a document. IDL Definition // Introduced in DOM Level 2: interface DocumentView { readonly attribute AbstractView defaultView; }; Attributes defaultView of type AbstractView, readonly The default AbstractView for this Document, or null if none available. 4. Document Object Model StyleSheets Editors Vidur Apparao, Netscape Communications Corp. Philippe Le Hégaret, W3C Chris Wilson, Microsoft 4.1. Introduction The DOM Level 2 Style Sheet interfaces are base interfaces used to represent any type of style sheet. The expectation is that DOM modules that represent a specific style sheet language may contain interfaces that derive from these interfaces. 4.2. Style Sheet Interfaces This set of interfaces represents the generic notion of style sheets. Interface StyleSheet (introduced in DOM Level 2) The StyleSheet interface is the abstract base interface for any type of style sheet. It represents a single style sheet associated with a structured document. In HTML, the StyleSheet interface represents either an external style sheet, included via the HTML LINK element, or an inline STYLE element. In XML, this interface represents an external style sheet, included via a style sheet processing instruction. IDL Definition // Introduced in DOM Level 2: interface StyleSheet { readonly attribute DOMString type; attribute boolean disabled; readonly attribute Node ownerNode; readonly attribute StyleSheet parentStyleSheet; readonly attribute DOMString href; readonly attribute DOMString title; readonly attribute MediaList media; }; Attributes type of type DOMString, readonly This specifies the style sheet language for this style sheet. The style sheet language is specified as a content type (e.g. "text/css"). The content type is often specified in the ownerNode. A list of registered content types can be found at ftp://ftp.isi.edu/in-notes/iana/assignments/media-types/. Also see the type attribute definition for the LINK element in HTML 4.0, and the type pseudo-attribute for the XML style sheet processing instruction. disabled of type boolean false if the style sheet is applied to the document. true if it is not. Modifying this attribute may cause a new resolution of style for the document. For the Document Object Model CSS, the medium has a higher priority than the disabled attribute. So, if the media doesn't apply to the current user agent, the disabled attribute is ignored. ownerNode of type Node, readonly The node that associates this style sheet with the document. For HTML, this may be the corresponding LINK or STYLE element. For XML, it may be the linking processing instruction. For style sheets that are included by other style sheets, the value of this attribute is null. parentStyleSheet of type StyleSheet, readonly For style sheet languages that support the concept of style sheet inclusion, this attribute represents the including style sheet, if one exists. If the style sheet is a top-level style sheet, or the style sheet language does not support inclusion, the value of this attribute is null. href of type DOMString, readonly If the style sheet is a linked style sheet, the value of its attribute is its location. For inline style sheets, the value of this attribute is null. See the href attribute definition for the LINK element in HTML 4.0, and the href pseudo-attribute for the XML style sheet processing instruction. title of type DOMString, readonly The advisory title. The title is often specified in the ownerNode. See the title attribute definition for the LINK element in HTML 4.0, and the title pseudo-attribute for the XML style sheet processing instruction. media of type MediaList, readonly The intended destination media for style information. The media is often specified in the ownerNode. If no media has been specified, the MediaList will be empty. See the media attribute definition for the LINK element in HTML 4.0, and the media pseudo-attribute for the XML style sheet processing instruction . Interface StyleSheetList (introduced in DOM Level 2) The StyleSheetList interface provides the abstraction of an ordered collection of style sheets. IDL Definition // Introduced in DOM Level 2: interface StyleSheetList { readonly attribute unsigned long length; StyleSheet item(in unsigned long index); }; Attributes length of type unsigned long, readonly The number of StyleSheet in the list. The range of valid child stylesheet indices is 0 to length-1 inclusive. Methods item Used to retrieve a style sheet by ordinal index. Parameters unsigned long index Index into the collection Return Value StyleSheet The style sheet at the index position in the StyleSheetList, or null if that is not a valid index. No Exceptions Interface MediaList (introduced in DOM Level 2) The MediaList interface provides the abstraction of an ordered collection of media, without defining or constraining how this collection is implemented. An empty list is the same as a list that contain the medium "all". IDL Definition // Introduced in DOM Level 2: interface MediaList { attribute DOMString cssText; // raises(DOMException) on setting readonly attribute unsigned long length; DOMString item(in unsigned long index); void delete(in DOMString oldMedium) raises(DOMException); void append(in DOMString newMedium) raises(DOMException); }; Attributes cssText of type DOMString The parsable textual representation of the media list. This is a comma-separated list of media. Exceptions on setting DOMException SYNTAX_ERR: Raised if the specified CSS string value has a syntax error and is unparsable. NO_MODIFICATION_ALLOWED_ERR: Raised if this media list is readonly. length of type unsigned long, readonly The number of media in the list. The range of valid media is 0 to length-1 inclusive. Methods item Returns the indexth in the list. If index is greater than or equal to the number of media in the list, this returns null. Parameters unsigned long index Index into the collection. Return Value DOMString The medium at the indexth position in the MediaList, or null if that is not a valid index. No Exceptions delete Deletes the medium indicated by oldMedium from the list. Parameters DOMString oldMedium The medium to delete in the media list. Exceptions DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if this list is readonly. NOT_FOUND_ERR: Raised if oldMedium is not in the list. No Return Value append Adds the medium newMedium to the end of the list. It the newMedium is already used, it is first removed. Parameters DOMString newMedium The new medium to add. Exceptions DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if this list is readonly. No Return Value 4.3. Document Extensions Interface LinkStyle The LinkStyle interface provides a mechanism by which a style sheet can be retrieved from the node responsible for linking it into a document. An instance of the LinkStyle interface can be obtained using binding-specific casting methods on an instance of a linking node (HTMLLinkElement, HTMLStyleElement or ProcessingInstruction in DOM Level 2). IDL Definition interface LinkStyle { readonly attribute StyleSheet sheet; }; Attributes sheet of type StyleSheet, readonly The style sheet. Interface DocumentStyle (introduced in DOM Level 2) The DocumentStyle interface provides a mechanism by which the style sheets embedded a document can be retrieved. The expectation is that an instance of the DocumentStyle interface can be obtained by using binding-specific casting methods on an instance of the Document interface. IDL Definition // Introduced in DOM Level 2: interface DocumentStyle { readonly attribute StyleSheetList styleSheets; }; Attributes styleSheets of type StyleSheetList, readonly A list containing all the style sheets explicitly linked into or embedded in a document. For HTML documents, this includes external style sheets, included via the HTML LINK element, and inline STYLE elements. In XML, this includes external style sheets, included via style sheet processing instructions. 4.4. Association between a style sheet and a document. HTML and Style Sheet Creation A style sheet can be associated with an HTMLDocument in one of two ways: o By creating a new LINK HTML element (see the HTMLLinkElement interface). The underlying style sheet will be created after the element is inserted into the document and both the href and the type attribute have been set in a way indicating that the linked object is a style sheet. o By creating a new STYLE HTML element (see the HTMLStyLeElement interface). The underlying style sheet will be created after the element is inserted into the document and the type attribute is set in a way indicating that the element corresponds to a style sheet language interpreted by the user agent. HTML and Style Sheet Removal Removing a LINK HTML element or a STYLE HTML element removes the underlying style sheet from the style sheet collection associated with a document. Specifically, the removed style sheet is no longer applied to the presentation of the document. XML and Style Sheet Creation A new style sheet can be created and associated an XML document by creating a processing instruction with the target 'xml-stylesheet' and inserting it into the document. XML and Style Sheet Removal Removing a processing instruction with a target of 'xml-stylesheet' removes the underlying style sheet from the style sheet collection associated with a document. Specifically, the removed style sheet is no longer applied to the presentation of the document. 5. Document Object Model CSS Editors Vidur Apparao, Netscape Communications Corp. Philippe Le Hégaret, W3C Chris Wilson, Microsoft 5.1. Overview of the DOM Level 2 CSS Interfaces The DOM Level 2 Cascading Style Sheets (CSS) interfaces are designed with the goal of exposing CSS constructs to object model consumers. Cascading Style Sheets is a declarative syntax for defining presentation rules, properties and ancillary constructs used to format and render Web documents. This document specifies a mechanism to programmatically access and modify the rich style and presentation control provided by CSS (specifically CSS level two [CSS2]). This augments CSS by providing a mechanism to dynamically control the inclusion and exclusion of individual style sheets, as well as manipulate CSS rules and properties. The CSS interfaces are organized in a logical, rather than physical structure. A collection of all style sheets referenced by or embedded in the document is accessible on the document interface. Each item in this collection exposes the properties common to all style sheets referenced or embedded in HTML and XML documents; this interface is described in the Style Sheets chapter of the DOM Level 2. User style sheets are not accessible through this collection, in part due to potential privacy concerns (and certainly read-write issues). For each CSS style sheet, an additional interface is exposed - the CSSStyleSheet interface. This interface allows access to the collection of rules within a CSS style sheet and methods to modify that collection. Interfaces are provided for each specific type of rule in CSS2 (e.g. style declarations, @import rules, or @font-face rules), as well as a shared generic CSSRule interface. The most common type of rule is a style declaration. The CSSStyleRule interface that represents this type of rule provides string access to the CSS selector of the rule, and access to the property declarations through the CSSStyleDeclaration interface. Finally, an optional CSS2Properties interface is described; this interface (if implemented) provides shortcuts to the string values of all the properties in CSS level 2. 5.2. CSS Fundamental Interfaces The interfaces within this section are considered fundamental, and must be supported by all conforming DOM implementations. These interfaces represent CSS style sheets specifically. A DOM application can use the hasFeature method of the DOMImplementation interface to determine whether the CSS interfaces are supported or not. The feature string for the fundamental interfaces listed in this section is "CSS". Exception CSSException This exception is raised when a specific CSS operation is impossible to perform. IDL Definition exception CSSException { unsigned short code; }; // CSSExceptionCode const unsigned short SYNTAX_ERR = 0; const unsigned short INVALID_MODIFICATION_ERR = 1; Definition group CSSExceptionCode An integer indicating the type of error generated. Defined Constants SYNTAX_ERR Raised when a string can't be parsed. INVALID_MODIFICATION_ERR Raised when an invalid modification is performed (see CSSRule). Interface CSSStyleSheet (introduced in DOM Level 2) The CSSStyleSheet interface is a concrete interface used to represent a CSS style sheet i.e. a style sheet whose content type is "text/css".

IDL Definition // Introduced in DOM Level 2: interface CSSUnknownRule : CSSRule { }; Interface CSSStyleDeclaration (introduced in DOM Level 2) The CSSStyleDeclaration interface represents a single CSS declaration block. This interface may be used to determine the style properties currently set in a block or to set style properties explicitly within the block. While an implementation may not recognize all CSS properties within a CSS declaration block, it is expected to provide access to all specified properties through the CSSStyleDeclaration interface. Furthermore, implementations that support a specific level of CSS should correctly handle CSS shorthand properties for that level. For a further discussion of shorthand properties, see the CSS2Properties interface. IDL Definition // Introduced in DOM Level 2: interface CSSStyleDeclaration { attribute DOMString cssText; // raises(CSSException, // DOMException) on setting DOMString getPropertyValue(in DOMString propertyName); CSSValue getPropertyCSSValue(in DOMString propertyName); DOMString removeProperty(in DOMString propertyName) raises(DOMException); DOMString getPropertyPriority(in DOMString propertyName); void setProperty(in DOMString propertyName, in DOMString value, in DOMString priority) raises(CSSException, DOMException); readonly attribute unsigned long length; DOMString item(in unsigned long index); readonly attribute CSSRule parentRule; }; Attributes cssText of type DOMString The parsable textual representation of the declaration block (including the surrounding curly braces).

No Parameters Interface CSSValueList (introduced in DOM Level 2) The CSSValueList interface provides the abstraction of an ordered collection of CSS values. Some properties allow an empty list into their syntax. In that case, these properties take the none identifier. So, an empty list means that the propertie has the value none. IDL Definition // Introduced in DOM Level 2: interface CSSValueList : CSSValue { readonly attribute unsigned long length; CSSValue item(in unsigned long index); }; Attributes length of type unsigned long, readonly The number of CSSValues in the list. The range of valid values indices is 0 to length-1 inclusive. For Methods item Used to retrieve a CSS rule by ordinal index.

Override and computed style sheet Interface ViewCSS This interface represents a CSS view. The getComputedStyle method provides a read only access to the computed values of an element. IDL Definition interface ViewCSS : views::AbstractView { CSSStyleDeclaration getComputedStyle(in Element elt, in DOMString pseudoElt); }; Methods getComputedStyle This method is used to the computed style sheet as it defines in the [CSS2]. Parameters Element elt The element. DOMString pseudoElt The pseudo element or null if any. Return Value CSSStyleDeclaration The computed style. The CSSStyleDeclaration is read only. No Exceptions Interface DocumentCSS This interface represents a document with a CSS view. The getOverrideStyle method provides a mechanism through which a DOM author could effect immediate change to the style of an element without modifying the explicitly linked stylesheets of a document or the inline style of elements in the stylesheets. This style sheet comes after the author style sheet in the cascade algorithm and is called override style sheet. The override style sheet takes over author style sheet. An "!important" declaration still takes precedence over a normal declaration. Both override and user style sheets may contain "!important" declarations, and user "!important" rules takes precedence over override "!important" rules. Both author and override style sheets may contain "!important" declarations, and override "!important" rules takes precedence over author "!important" rules. IDL Definition interface DocumentCSS : stylesheets::DocumentStyle { CSSStyleDeclaration getOverrideStyle(in Element elt, in DOMString pseudoElt); }; Methods getOverrideStyle This method is used to retrieve the override style sheet. Parameters Element elt The element to be modified. DOMString pseudoElt The pseudo element or null if any. Return Value CSSStyleDeclaration The override style declaration. No Exceptions 5.2.2. Style sheet creation Interface DOMImplementationCSS (introduced in DOM Level 2) This interface allows the DOM user to create a CSS style sheet outside the context of a document. There is no way to associate the new CSS style sheet with a document in DOM Level 2. IDL Definition // Introduced in DOM Level 2: interface DOMImplementationCSS : DOMImplementation { CSSStyleSheet createCSSStyleSheet(in DOMString title, inout DOMString media); }; Methods createCSSStyleSheet Creates a new CSS style sheet. Parameters DOMString title The advisory title. See also Document Object Model StyleSheets. DOMString media The media associated to the new style sheet. See also Document Object Model StyleSheets. Return Value CSSStyleSheet A new CSS style sheet. No Exceptions 5.3. CSS Extended Interfaces The interfaces found within this section are not mandatory. A DOM application can use the hasFeature method of the DOMImplementation interface to determine whether they are supported or not. The feature string for all the extended interfaces listed in this section, except the CSS2Properties interface, is "CSS2". The following table specifies the type of CSSValue used to represent each property that can be specified in a CSSStyleDeclaration found in a CSSStyleRule for a CSS Level 2 style sheet. The expectation is that the CSSValue returned from the getPropertyCSSValue method on the CSSStyleDeclaration interface can be cast down, using binding-specific casting methods, to the specific derived interface. For properties that are represented by a custom interface (the valueType of the CSSValue is CSS_CUSTOM), the name of the derived interface is specified in the table.

No Return Value The following interface may be supported by a DOM implementation as a convenience. A DOM application can use the hasFeature method of the DOMImplementation interface to determine whether the CSS2Properties interface is supported or not. The feature string for the CSS2Properties interface is "CSS2Properties". Interface CSS2Properties (introduced in DOM Level 2) The CSS2Properties interface represents a convenience mechanism for retrieving and setting properties within a CSSStyleDeclaration. The attributes of this interface correspond to all the properties specified in CSS2. Getting an attribute of this interface is equivalent to calling the getPropertyValue method of the CSSStyleDeclaration interface. Setting an attribute of this interface is equivalent to calling the setProperty method of the CSSStyleDeclaration interface. A compliant implementation is not required to implement the CSS2Properties interface. If an implementation does implement this interface, the expectation is that language-specific methods can be used to cast from an instance of the CSSStyleDeclaration interface to the CSS2Properties interface. If an implementation does implement this interface, it is expected to understand the specific syntax of the shorthand properties, and apply their semantics; when the margin property is set, for example, the marginTop, marginRight, marginBottom and marginLeft properties are actually being set by the underlying implementation. When dealing with CSS "shorthand" properties, the shorthand properties should be decomposed into their component longhand properties as appropriate, and when querying for their value, the form returned should be the shortest form exactly equivalent to the declarations made in the ruleset. However, if there is no shorthand declaration that could be added to the ruleset without changing in any way the rules already declared in the ruleset (i.e., by adding longhand rules that were previously not declared in the ruleset), then the empty string should be returned for the shorthand property. For example, querying for the font property should not return "normal normal normal 14pt/normal Arial, sans-serif", when "14pt Arial, sans-serif" suffices (the normals are initial values, and are implied by use of the longhand property). If the values for all the longhand properties that compose a particular string are the initial values, then a string consisting of all the initial values should be returned (e.g. a border-width value of "medium" should be returned as such, not as ""). For some shorthand properties that take missing values from other sides, such as the margin, padding, and border-[width|style|color] properties, the minimum number of sides possible should be used, i.e., "0px 10px" will be returned instead of "0px 10px 0px 10px". If the value of a shorthand property can not be decomposed into its component longhand properties, as is the case for the font property with a value of "menu", querying for the values of the component longhand properties should return the empty string.

IDL Definition // Introduced in DOM Level 2: interface HTMLElementCSS : html::HTMLElement { readonly attribute CSSStyleDeclaration style; }; Attributes style of type CSSStyleDeclaration, readonly The style attribute. 5.5. Unresolved Issues 1. We do not intend to provide access to the actual style of specific elements in this level of the CSS DOM. Implementation of the CSS DOM does not require an actual rendering engine for any other reason, and we see that requirement as a limitation on the potential implementations of the CSS DOM. 2. The group is undecided whether to put a cssText attribute on the CSSStyleSheet, which would provide a textual representation of the entire style sheet. Setting this attribute would result in the resetting of all the rules in the style sheet. 6. Document Object Model Events Editors Tom Pixley, Netscape Communications Corporation 6.1. Overview of the DOM Level 2 Event Model The DOM Level 2 Event Model is designed with two main goals. The first goal is the design of a generic event system which allows registration of event handlers, describes event flow through a tree structure, and provides basic contextual information for each event. Additionally, the specification will provide standard sets of events for user interface control and document mutation notifications, including defined contextual information for each of these event sets. The second goal of the event model is to provide a common subset of the current event systems used in DOM Level 0 browsers. This is intended to foster interoperability of existing scripts and content. It is not expected that this goal will be met with full backwards compatibility. However, the specification attempts to achieve this when possible. The following sections of the Event Model specification define both the specification for the DOM Event Model and a number of compliant event sets designed for use within the model. The Event Model consists of the two sections on event propagation and event listener registration and the Event interface. A DOM consumer can use the hasFeature of the DOMImplementation interface to determine whether the Event Model has been implemented by a DOM implementation. The feature string for the Event Model is "Events". The existence within an implementation of each of the individual event sets can also be queried using the hasFeature method. Each event set describes its own feature string in the event set listing. 6.1.1. Terminology UI events User interface events. These events are generated by user interaction through an external device (mouse, keyboard, etc.) UI Logical events Device independent user interface events such as focus change messages or element triggering notifications. Mutation events Events caused by any action which modifies the structure of the document. Capturing The process by which an event can be handled by one of the event's target's ancestors before being handled by the event's target. Bubbling The process by which an event propagates upward through its ancestors after being handled by the event's target. Cancelable A designation for events which indicates that upon handling the event the client may choose to prevent the DOM implementation from processing any default action associated with the event. 6.2. Description of event flow Event flow is the process through which the an event originates from the DOM implementation and is passed into the Document Object Model. The methods of event capture and event bubbling, along with various event listener registration techniques, allow the event to then be handled in a number of ways. It can be handled locally at the EventTarget level or centrally from an EventTarget higher in the document tree. 6.2.1. Basic event flow Each event has an EventTarget toward which the event is directed by the DOM implementation. This EventTarget is specified in the Event's target attribute. When the event reaches the target, any event listeners registered on the EventTarget are triggered. Although all EventListeners on the EventTarget are guaranteed to receive the event, no specification is made as to the order in which they will receive the event with regards to the other EventListeners on the EventTarget. If neither event capture or event bubbling are in use for that particular event, the event flow process will complete after all listeners have been triggered. If event capture or event bubbling is in use, the event flow will be modified as described in the sections below. Any exceptions thrown inside an EventListener will not stop propagation of the event. It will continue processing any additional EventListener in the described manner. 6.2.2. Event Capture Event capture is the process by which an EventListener registered on an ancestor of the event's target can intercept events of a given type before they are received by the event's target. Capture operates from the top of the tree downward, making it the symmetrical opposite of bubbling which is described below. An EventListener being registered on an EventTarget may choose to have that EventListener capture events by specifying the useCapture parameter of the addEventListener method to be true. Thereafter, when an event of the given type is dispatched toward a descendant of the capturing object, the event will trigger any capturing event listeners of the appropriate type which exist in the direct line between the top of the document and the event's target. This downward propagation continues until the event's target is reached. A capturing EventListener will not be triggered by events dispatched directly the the EventTarget upon which it is registered. If the capturing EventListener wishes to prevent further processing of the event, either later in the capture phase or during bubbling, it may call the preventCapture method of the Event interface. This will prevent further dispatch of the event to additional EventTargets lower in the tree structure, although additional EventListeners registered at the same hierarchy level will still receive the event. Once an event's preventCapture method has been called, further calls to that method have no additional effect. If no additional capturers exist and preventCapture has not been called, the event triggers the appropriate EventListeners on the target itself. Although event capture is similar to the delegation based event model in which all interested parties register their listeners directly on the target about which they wish to receive notifications, it is different in two important respects. First, event capture only allows interception of events which are targeted at descendants of the capturing Node. It does not allow interception of events targeted to the capturer's ancestors, its siblings, or its sibling's descendants. Secondly, event capture is not specified for a single Node, it is specified for a specific type of event. Once specified, event capture intercepts all events of the specified type targeted toward any of the capturer's descendants. 6.2.3. Event bubbling Events which are designated as bubbling will initially proceed with the same event flow as non-bubbling events. The event is dispatched to its target Node and any event listeners found there are triggered. Bubbling events will then trigger any additional event listeners found by following the Node's parent chain upward, checking for any event listeners registered on each successive Node. This upward propagation will continue up to and including the Document. Any event handler may choose to prevent continuation of the bubbling process by calling the preventBubble method of the Event interface. If any EventListener calls this method, all additional EventListeners on the current EventTarget will be triggered but bubbling will cease at that level. Only one call to preventBubble is required to prevent further bubbling. 6.2.4. Event cancelation Some events are specified as cancelable. For these events, the DOM implementation generally has a default action associated with the event. Before processing these events, the implementation must check for event listeners registered to receive the event and dispatch the event to those listeners. These listeners then have the option of canceling the implementation's default action or allowing the default action to proceed. Cancelation is accomplished by calling the Event's preventDefault method. If one or more EventListeners call preventDefault during any phase of event flow the default action will be canceled. 6.3. Event listener registration 6.3.1. Event registration interfaces Interface EventTarget (introduced in DOM Level 2) The EventTarget interface is implemented by all Nodes in an implementation which supports the DOM Event Model. The interface allows registration and removal of EventListeners on an EventTarget and dispatch of events to that EventTarget. IDL Definition // Introduced in DOM Level 2: interface EventTarget { void addEventListener(in DOMString type, in EventListener listener, in boolean useCapture); void removeEventListener(in DOMString type, in EventListener listener, in boolean useCapture); boolean dispatchEvent(in Event evt) raises(DOMException); }; Methods addEventListener This method allows the registration of event listeners on the event target. Parameters DOMString type The event type for which the user is registering EventListener listener The listener parameter takes an interface implemented by the user which contains the methods to be called when the event occurs. boolean useCapture If true, useCapture indicates that the user wishes to initiate capture. After initiating capture, all events of the specified type will be dispatched to the registered EventListener before being dispatched to any EventTargets beneath them in the tree. Events which are bubbling upward through the tree will not trigger an EventListener designated to use capture. If an EventListener is added to an EventTarget which is currently processing an event the new listener will not be triggered by the current event. No Return Value No Exceptions removeEventListener This method allows the removal of event listeners from the event target. If an EventListener is removed from an EventTarget while it is processing an event, it will complete its current actions but will not be triggered again during any later stages of event flow. If an EventListener is removed from an EventTarget which is currently processing an event the removed listener will still be triggered by the current event. Parameters DOMString type Specifies the event type of the EventListener being removed. EventListener listener The EventListener parameter indicates the EventListener to be removed. boolean useCapture Specifies whether the EventListener being removed was registered as a capturing listener or not. If a listener was registered twice, one with capture and one without, each must be removed separately. Removal of a capturing listener does not affect a non-capturing version of the same listener, and vice versa. No Return Value No Exceptions dispatchEvent This method allows the dispatch of events into the implementations event model. Events dispatched in this manner will have the same capturing and bubbling behavior as events dispatched directly by the implementation. The target of the event is the EventTarget on which dispatchEvent is called. Parameters Event evt Specifies the event type, behavior, and contextual information to be used in processing the event. Return Value boolean The return value of dispatchEvent indicates whether any of the listeners which handled the event called preventDefault. If preventDefault was called the value is false, else the value is true. Exceptions DOMException UNSPECIFIED_EVENT_TYPE: Raised if the Event's type was not specified by initializing the event before dispatchEvent was called. Interface EventListener (introduced in DOM Level 2) The EventListener interface is the primary method for handling events. Users implement the EventListener interface and register their listener on an EventTarget using the AddEventListener method. The users should also remove their EventListener from its EventTarget after they have completed using the listener. IDL Definition // Introduced in DOM Level 2: interface EventListener { void handleEvent(in Event evt); }; Methods handleEvent This method is called whenever an event occurs of the type for which the EventListener interface was registered. Parameters Event evt The Event contains contextual information about the event. It also contains the preventDefault, preventBubble, and preventCapture methods which are used in determining the event's flow and default action. No Return Value No Exceptions 6.3.2. Interaction with HTML 4.0 event listeners In HTML 4.0, event listeners were specified as attributes of an element. As such, registration of a second event listener of the same type would replace the first listener. The DOM Event Model allows registration of multiple event listeners on a single Node. To achieve this, event listeners are no longer stored as attribute values. In order to achieve compatibility with HTML 4.0, implementors may view the setting of attributes which represent event handlers as the creation and registration of an EventListener on the Node. The value of useCapture defaults to false. This EventListener behaves in the same manner as any other EventListeners which may be registered on the EventTarget. If the attribute representing the event listener is changed, this may be viewed as the removal of the previously registered EventListener and the registration of a new one. No technique is provided to allow HTML 4.0 event listeners access to the context information defined for each event. 6.4. Event interface Interface Event (introduced in DOM Level 2) The Event interface is used to provide contextual information about an event to the handler processing the event. An object which implements the Event interface is generally passed as the first parameter to an event handler. More specific context information is passed to event handlers by deriving additional interfaces from Event which contain information directly relating to the type of event they accompany. These derived interfaces are also implemented by the object passed to the event listener. IDL Definition // Introduced in DOM Level 2: interface Event { // PhaseType const unsigned short BUBBLING_PHASE = 1; const unsigned short CAPTURING_PHASE = 2; const unsigned short AT_TARGET = 3; readonly attribute DOMString type; readonly attribute EventTarget target; readonly attribute Node currentNode; readonly attribute unsigned short eventPhase; readonly attribute boolean bubbles; readonly attribute boolean cancelable; void preventBubble(); void preventCapture(); void preventDefault(); void initEvent(in DOMString eventTypeArg, in boolean canBubbleArg, in boolean cancelableArg); }; Definition group PhaseType An integer indicating which phase of event flow is being processed. Defined Constants BUBBLING_PHASE The current event phase is the bubbling phase. CAPTURING_PHASE The current event phase is the capturing phase. AT_TARGET The event is currently being evaluated at the target node. Attributes type of type DOMString, readonly The type property represents the event name as a string property. target of type EventTarget, readonly The target property indicates the EventTarget to which the event was originally dispatched. currentNode of type Node, readonly The currentNode property indicates the Node whose EventListeners are currently being processed. This is particularly useful during capturing and bubbling. eventPhase of type unsigned short, readonly The eventPhase property indicates which phase of event flow is currently being evaluated. bubbles of type boolean, readonly The bubbles property indicates whether or not an event is a bubbling event. If the event can bubble the value is true, else the value is false. cancelable of type boolean, readonly The cancelable property indicates whether or not an event can have its default action prevented. If the default action can be prevented the value is true, else the value is false. Methods preventBubble The preventBubble method is used to end the bubbling phase of event flow. If this method is called by any EventListeners registered on the same EventTarget during bubbling, the bubbling phase will cease at that level and the event will not be propagated upward within the tree. No Parameters No Return Value No Exceptions preventCapture The preventCapture method is used to end the capturing phase of event flow. If this method is called by any EventListeners registered on the same EventTarget during capturing, the capturing phase will cease at that level and the event will not be propagated any further down. No Parameters No Return Value No Exceptions preventDefault If an event is cancelable, the preventCapture method is used to signify that the event is to be canceled, meaning any default action normally taken by the implementation as a result of the event will not occur . If, during any stage of event flow, the preventDefault method is called the event is canceled. Any default action associated with the event will not occur. Calling this method for a non-cancelable event has no effect. Once preventDefault has been called it will remain in effect throughout the remainder of the event's propagation. No Parameters No Return Value No Exceptions initEvent Parameters DOMString eventTypeArg Specifies the event type. This type may be any event type currently defined in this specification or a new event type. Any new event type must not begin with any upper, lower, or mixed case version of the string "DOM". This prefix is reserved for future DOM event sets. boolean canBubbleArg Specifies whether or not the event can bubble. boolean cancelableArg Specifies whether or not the event's default action can be prevented. No Return Value No Exceptions 6.5. DocumentEvent interface Interface DocumentEvent (introduced in DOM Level 2) The DocumentEvent interface provides a mechanism by which the a user can create an Event of a type supported by the implementation. It is expected that the DocumentEvent interface will be implemented on the same object which implements the Document interface in an implementation which supports the Event model. IDL Definition // Introduced in DOM Level 2: interface DocumentEvent { Event createEvent(in DOMString type) raises(DOMException); }; Methods createEvent Parameters DOMString type The type paramater specifies the type of Event to be created. If the Event type specified is supported by the implementation this method will return a new Event of the type requested. If the Event is to be dispatched via the dispatchEvent method the appropriate event init method must be called after creation in order to initialize the Event's values. Return Value Event The newly created Event Exceptions DOMException UNSUPPORTED_EVENT_TYPE: Raised if the implementation does not support the type of Event requested 6.6. Event set definitions The DOM Level 2 Event Model allows a DOM implementation to support multiple sets of events. The model has been designed to allow addition of new event sets as is required. The DOM will not attempt to define all possible events. For purposes of interoperability, the DOM will define a set of user interface events including lower level device dependent events, a set of UI logical events, and a set of document mutation events. 6.6.1. User Interface event types The User Interface event set is composed of events listed in HTML 4.0 and additional events which are supported in DOM Level 0 browsers. A DOM consumer can use the hasFeature of the DOMImplementation interface to determine whether the User Interface event set has been implemented by a DOM implementation. The feature string for this event set is "UIEvents". Interface UIEvent (introduced in DOM Level 2) The UIEvent interface provides specific contextual information associated with User Interface events. IDL Definition // Introduced in DOM Level 2: interface UIEvent : Event { readonly attribute views::AbstractView view; readonly attribute unsigned short detail; void initUIEvent(in DOMString typeArg, in boolean canBubbleArg, in boolean cancelableArg, in views::AbstractView viewArg, in unsigned short detailArg); }; Attributes view of type views::AbstractView, readonly The view attribute identifies the AbstractView from which the event was generated. detail of type unsigned short, readonly Specifies some detail information about the Event, depending on the type of event. Methods initUIEvent Parameters DOMString typeArg Specifies the event type. boolean canBubbleArg Specifies whether or not the event can bubble. boolean cancelableArg Specifies whether or not the event's default action can be prevent. views::AbstractView viewArg Specifies the Event's AbstractView. unsigned short detailArg Specifies the Event's detail. No Return Value No Exceptions The different types of such events that can occur are: resize The resize event occurs when a document view is resized. o Bubbles: Yes o Cancelable: No o Context Info: None scroll The scroll event occurs when a document view is scrolled. o Bubbles: Yes o Cancelable: No o Context Info: None focusin The focusin event occurs when a node receives focus, for instance via a pointing device being moved onto an element or by tabbing navigation to the element. Unlike the HTML event focus, focusin can be applied to any node, not just FORM controls. o Bubbles: No o Cancelable: No o Context Info: None focusout The focusout event occurs when a node loses focus, for instance via a pointing device being moved out of an element or by tabbing navigation out of the element. Unlike the HTML event blur, focusout can be applied to any node, not just FORM controls. o Bubbles: No o Cancelable: No o Context Info: None gainselection The gainselection event occurs when a node or part of it is selected (unlike the HTML event select, it can be applied to any element, not just HTML FORM controls). For each selected node a gainselection event, which can be handled locally or thru bubbling by a root node selection handler, is generated. o Bubbles: Yes o Cancelable: No o Context Info: range loseselection The loseselection event occurs when a node or part of it is deselected, for example because the user selects something else. o Bubbles: Yes o Cancelable: No o Context Info: range activate The activate event occurs when an element is activated, for instance, thru a mouse click or a keypress. A numerical argument is provided to give an indication of the type of activation that occurs: 1 for a simple activation (e.g. a simple click or Enter), 2 for hyperactivation (for instance a double click or Shift Enter). o Bubbles: Yes o Cancelable: Yes o Context Info: detail (the numerical value) 6.6.2. Mouse event types The Mouse event set is composed of events listed in HTML 4.0 and additional events which are supported in DOM Level 0 browsers. This event set is specifically for use with mouse input devices. A DOM consumer can use the hasFeature of the DOMImplementation interface to determine whether the User Interface event set has been implemented by a DOM implementation. The feature string for this event set is "MouseEvents". Interface MouseEvent (introduced in DOM Level 2) The MouseEvent interface provides specific contextual information associated with Mouse events. The detail attribute inherited from UIEvent indicates the number of times a mouse button has been pressed and released over the same screen location during a user action. The attribute value is 1 when the user begins this action and increments by 1 for each full sequence of pressing and releasing. If the user moves the mouse between the mousedown and mouseup the value will be set to 0, indicating that no click is occurring. IDL Definition // Introduced in DOM Level 2: interface MouseEvent : UIEvent { readonly attribute long screenX; readonly attribute long screenY; readonly attribute long clientX; readonly attribute long clientY; readonly attribute boolean ctrlKey; readonly attribute boolean shiftKey; readonly attribute boolean altKey; readonly attribute boolean metaKey; readonly attribute unsigned short button; readonly attribute Node relatedNode; void initMouseEvent(in DOMString typeArg, in boolean canBubbleArg, in boolean cancelableArg, in views::AbstractView viewArg, in unsigned short detailArg, in long screenXArg, in long screenYArg, in long clientXArg, in long clientYArg, in boolean ctrlKeyArg, in boolean altKeyArg, in boolean shiftKeyArg, in boolean metaKeyArg, in unsigned short buttonArg, in Node relatedNodeArg); }; Attributes screenX of type long, readonly screenX indicates the horizontal coordinate at which the event occurred in relative to the origin of the screen coordinate system. screenY of type long, readonly screenY indicates the vertical coordinate at which the event occurred relative to the origin of the screen coordinate system. clientX of type long, readonly clientX indicates the horizontal coordinate at which the event occurred relative to the DOM implementation's client area. clientY of type long, readonly clientY indicates the vertical coordinate at which the event occurred relative to the DOM implementation's client area. ctrlKey of type boolean, readonly ctrlKey indicates whether the 'ctrl' key was depressed during the firing of the event. shiftKey of type boolean, readonly shiftKey indicates whether the 'shift' key was depressed during the firing of the event. altKey of type boolean, readonly altKey indicates whether the 'alt' key was depressed during the firing of the event. On some platforms this key may map to an alternative key name. metaKey of type boolean, readonly metaKey indicates whether the 'meta' key was depressed during the firing of the event. On some platforms this key may map to an alternative key name. button of type unsigned short, readonly During mouse events caused by the depression or release of a mouse button, button is used to indicate which mouse button changed state. relatedNode of type Node, readonly relatedNode is used to identify a secondary node related to a UI event. Methods initMouseEvent Parameters DOMString typeArg Specifies the event type. boolean canBubbleArg Specifies whether or not the event can bubble. boolean cancelableArg Specifies whether or not the event's default action can be prevent. views::AbstractView viewArg Specifies the Event's AbstractView. unsigned short detailArg Specifies the Event's mouse click count. long screenXArg Specifies the Event's screen x coordinate long screenYArg Specifies the Event's screen y coordinate long clientXArg Specifies the Event's client x coordinate long clientYArg Specifies the Event's client y coordinate boolean ctrlKeyArg Specifies whether or not control key was depressed during the Event. boolean altKeyArg Specifies whether or not alt key was depressed during the Event. boolean shiftKeyArg Specifies whether or not shift key was depressed during the Event. boolean metaKeyArg Specifies whether or not meta key was depressed during the Event. unsigned short buttonArg Specifies the Event's mouse button. Node relatedNodeArg Specifies the Event's related Node. No Return Value No Exceptions The different types of Mouse events that can occur are: click The click event occurs when the pointing device button is clicked over an element. A click is defined as a mousedown and mouseup over the same screen location. The sequence of these events is: mousedown mouseup click If multiple clicks occur at the same screen location, the sequence repeats with the detail attribute incrementing with each repetition. This event is valid for most elements. o Bubbles: Yes o Cancelable: Yes o Context Info: screenX, screenY, clientX, clientY, altKey, ctrlKey, shiftKey, metaKey, button, detail mousedown The mousedown event occurs when the pointing device button is pressed over an element. This event is valid for most elements. o Bubbles: Yes o Cancelable: Yes o Context Info: screenX, screenY, clientX, clientY, altKey, ctrlKey, shiftKey, metaKey, button, detail mouseup The mouseup event occurs when the pointing device button is released over an element. This event is valid for most elements. o Bubbles: Yes o Cancelable: Yes o Context Info: screenX, screenY, clientX, clientY, altKey, ctrlKey, shiftKey, metaKey, button, detail mouseover The mouseover event occurs when the pointing device is moved onto an element. This event is valid for most elements. o Bubbles: Yes o Cancelable: Yes o Context Info: screenX, screenY, clientX, clientY, altKey, ctrlKey, shiftKey, metaKey, relatedNode mousemove The mousemove event occurs when the pointing device is moved while it is over an element.

Key event types The Key event set is composed of events listed in HTML 4.0 and additional events which are supported in DOM Level 0 browsers. This event set is specifically for use with keyboard input devices. A DOM consumer can use the hasFeature of the DOMImplementation interface to determine whether the Key event set has been implemented by a DOM implementation. The feature string for this event set is "KeyEvents". Interface KeyEvent (introduced in DOM Level 2) The KeyEvent interface provides specific contextual information associated with Key events.

Mutation event types The mutation event set is designed to allow notification of any changes to the structure of a document, including attr and text modifications. It may be noted that none of the mutation events listed are designated as cancelable. This stems from the fact that it is very difficult to make use of existing DOM interfaces which cause document modifications if any change to the document might or might not take place due to cancelation of the related event. Although this is still a desired capability, it was decided that it would be better left until the addition of transactions into the DOM. A DOM consumer can use the hasFeature of the DOMImplementation interface to determine whether the mutation event set has been implemented by a DOM implementation. The feature string for this event set is "MutationEvents". Interface MutationEvent (introduced in DOM Level 2) The MutationEvent interface provides specific contextual information associated with Mutation events. IDL Definition // Introduced in DOM Level 2: interface MutationEvent : Event { readonly attribute Node relatedNode; readonly attribute DOMString prevValue; readonly attribute DOMString newValue; readonly attribute DOMString attrName; void initMutationEvent(in DOMString typeArg, in boolean canBubbleArg, in boolean cancelableArg, in Node relatedNodeArg, in DOMString prevValueArg, in DOMString newValueArg, in DOMString attrNameArg); }; Attributes relatedNode of type Node, readonly relatedNode is used to identify a secondary node related to a mutation event. For example, if a mutation event is dispatched to a node indicating that its parent has changed, the relatedNode is the changed parent. If an event is instead dispatch to a subtree indicating a node was changed within it, the relatedNode is the changed node. prevValue of type DOMString, readonly prevValue indicates the previous value of text nodes and attributes in attrModified and charDataModified events. newValue of type DOMString, readonly newValue indicates the new value of text nodes and attributes in attrModified and charDataModified events. attrName of type DOMString, readonly attrName indicates the changed attr in the attrModified event. Methods initMutationEvent Parameters DOMString typeArg Specifies the event type. boolean canBubbleArg Specifies whether or not the event can bubble. boolean cancelableArg Specifies whether or not the event's default action can be prevent. Node relatedNodeArg Specifies the Event's related Node DOMString prevValueArg Specifies the Event's prevValue property DOMString newValueArg Specifies the Event's newValue property DOMString attrNameArg Specifies the Event's attrName property No Return Value No Exceptions The different types of Mutation events that can occur are: DOMSubtreeModified This is a general event for notification of all changes to the document. It can be used instead of the more specific events listed below. Also, the requirement for some sort of batching of mutation events may be accomplished through this event. The target of this event is the lowest common parent of the changes which have taken place. This event is dispatched after any other events caused by the mutation have fired. o Bubbles: Yes o Cancelable: No o Context Info: None DOMNodeInserted Fired when a node has been added as a child of another node. This event is dispatched after the insertion has taken place. The target of this event is the node being inserted. o Bubbles: Yes o Cancelable: No o Context Info: relatedNode holds the parent node DOMNodeRemoved Fired when a node is being removed from another node. This event is dispatched before the node is removed from the tree. The target of this event is the node being removed. o Bubbles: Yes o Cancelable: No o Context Info: relatedNode holds the parent node DOMNodeRemovedFromDocument Fired when a node is being removed from a document, either through direct removal of the Node or removal of a subtree in which it is contained. This event is dispatched before the removal takes place. The target of this event is the node being removed. If the Node is being directly removed the nodeRemoved event will fire before the nodeRemovedFromDocument event. o Bubbles: No o Cancelable: No o Context Info: None DOMNodeInsertedIntoDocument Fired when a node is being inserted into a document, either through direct insertion of the Node or insertion of a subtree in which it is contained. This event is dispatched after the insertion has taken place. The target of this event is the node being inserted. If the Node is being directly inserted the nodeInserted event will fire before the nodeInsertedIntoDocument event. o Bubbles: No o Cancelable: No o Context Info: None DOMAttrModified Fired after an Attr has been modified on a node. The target of this event is the node whose Attr changed. o Bubbles: Yes o Cancelable: No o Context Info: attrName, prevValue, newValue DOMCharacterDataModified Fired after CharacterData within a node has been modified but the node itself has not been inserted or deleted. The target of this event is the CharacterData node. o Bubbles: Yes o Cancelable: No o Context Info: prevValue, newValue 6.6.5. HTML event types The HTML event set is composed of events listed in HTML 4.0 and additional events which are supported in DOM Level 0 browsers. A DOM consumer can use the hasFeature of the DOMImplementation interface to determine whether the HTML event set has been implemented by a DOM implementation. The feature string for this event set is "HTMLEvents". The HTML events use the base DOM Event interface to pass contextual information. The different types of such events that can occur are: load The load event occurs when the DOM implementation finishes loading all content within a document, all frames within a FRAMESET, or an OBJECT element. o Bubbles: No o Cancelable: No o Context Info: None unload The unload event occurs when the DOM implementation removes a document from a window or frame. This event is valid for BODY and FRAMESET elements. o Bubbles: No o Cancelable: No o Context Info: None abort The abort event occurs when page loading is stopped before an image has been allowed to completely load. This event applies to OBJECT elements. o Bubbles: Yes o Cancelable: No o Context Info: None error The error event occurs when an image does not load properly or when an error occurs during script execution. This event is valid for OBJECT elements, BODY elements, and FRAMESET element. o Bubbles: Yes o Cancelable: No o Context Info: None select The select event occurs when a user selects some text in a text field. This event is valid for INPUT and TEXTAREA elements. o Bubbles: Yes o Cancelable: No o Context Info: None change The change event occurs when a control loses the input focus and its value has been modified since gaining focus. This event is valid for INPUT, SELECT, and TEXTAREA. element. o Bubbles: Yes o Cancelable: No o Context Info: None submit The submit event occurs when a form is submitted. This event only applies to the FORM element. o Bubbles: Yes o Cancelable: Yes o Context Info: None reset The reset event occurs when a form is reset. This event only applies to the FORM element. o Bubbles: Yes o Cancelable: No o Context Info: None focus The focus event occurs when an element receives focus either via a pointing device or by tabbing navigation. This event is valid for the following elements: LABEL, INPUT, SELECT, TEXTAREA, and BUTTON. o Bubbles: No o Cancelable: No o Context Info: None blur The blur event occurs when an element loses focus either by the pointing device or by tabbing navigation. This event is valid for the following elements: LABEL, INPUT, SELECT, TEXTAREA, and BUTTON. o Bubbles: No o Cancelable: No o Context Info: None 7. Document Object Model Traversal Editors Mike Champion, Software AG Joe Kesselman, IBM Jonathan Robie, Software AG 7.1. Overview The DOM Level 2 TreeWalker, NodeIterator, and, Filter interfaces provide simple and efficient traversal for document nodes. The TreeWalker, NodeIterator, and Filter interfaces are optional. A DOM application can use the hasFeature method of the DOMImplementation interface to determine whether they are supported or not. The feature string for all the interfaces listed in this section is "Traversal". Iterators and TreeWalkers are two different ways of representing the nodes of a document subtree and a position within that collection. An Iterator flattens a subtree into an ordered list of document nodes, presented in document order. Because this is a flat list, presented without respect to hierarchy, Iterators have methods to move forward and backward, but not to move up and down. A TreeWalker maintains the hierarchical relationships of the subtree, allowing navigation of this hierarchy. Iterators and TreeWalkers each present a view of a document subtree that may not contain all nodes found in the subtree. In this specification, we refer to this as the logical view to distinguish it from the physical view, which corresponds to the document subtree per se. When an Iterator or TreeWalker is created, it may be associated with a Filter, which examines a node and determines whether it should be appear in the logical view. In addition, flags may be used to specify which node types should occur in the logical view. Iterators and TreeWalkers are dynamic - the logical view changes to reflect changes made to the underlying document. 7.1.1. Iterators An Iterator allows a list of nodes to be returned sequentially. In the current DOM interfaces, this list will always consist of the nodes of a subtree, presented in document order. When an Iterator is first created, calling nextNode() returns the first node in the logical view of the subtree; in most cases, this is the root of the subtree. When no more nodes are present, nextNode() returns null. Iterators are created using the createNodeIterator method found in the DocumentTraversal interface. When an Iterator is created, flags can be used to determine which node types will be "visible" and which nodes will be "invisible" while traversing the tree; these flags can be combined using the OR operator. Nodes that are "invisible" are skipped over by the Iterator as though they did not exist. The following code creates an Iterator, then calls a function to print the name of each element: NodeIterator iter=document.createNodeIterator(root, SHOW_ELEMENT, null); while (Node n = iter.nextNode()) printMe(n); 7.1.1.1. Moving Forward and Backward Iterators present nodes as an ordered list, and move forward and backward within this list. The Iterator's position is always between two nodes, before the first node, or after the last node. When an Iterator is first created, the position is set before the first item. The following diagram shows the list view that an Iterator might provide for a particular subtree, with the position indicated by an asterisk '*' : * A B C D E F G H I Each call to nextNode() returns the next node and advances the position. For instance, if we start with the above position, the first call to nextNode() returns "A" and advances the Iterator: [A] * B C D E F G H I An iterator uses the node last returned to maintain its position. This node is known as the reference node. In these diagrams, we use square brackets to indicate the reference node. A call to previousNode() returns the previous node and moves the position backward. For instance, if we start with the Iterator between "A" and "B", it would return "A" and move to the position shown below: * [A] B C D E F G H I If nextNode() is called at the end of a list, or previousNode() is called at the beginning of a list, it returns null and does not change the position of the Iterator. When an Iterator is first created, the reference node is the first node: * [A] B C D E F G H I 7.1.1.2. Robustness An Iterator may be active while the data structure it navigates is being edited, so an Iterator must behave gracefully in the face of change. Additions and removals in the underlying data structure do not invalidate an Iterator; in fact, an Iterator is never invalidated. To make this possible, the Iterator uses the reference node to maintain its position. The state of an Iterator also depends on whether the Iterator is positioned before or after the reference node. If the reference node is removed, another node becomes the reference node. If changes to the iterated list do not remove the reference node, they do not affect the state of the Iterator. For instance, the Iterator's state is not affected by inserting new nodes in the vicinity of the iterator or removing nodes other than the reference node. Suppose we start from the following position: A B C [D] * E F G H I Now let's remove "E". The resulting state is: A B C [D] * F G H I If a new node is inserted, the iterator stays close to the reference node, so if a node is inserted between "D" and "F", it will occur between the Iterator and "F": A B C [D] * X F G H I Moving a node is equivalent to a removal followed by an insertion. If we move "I" to the position before "X" the result is: A B C [D] * I X F G H If the reference node is removed, a different node is selected as the reference node. If the reference node is before the Iterator, which is usually the case after nextNode() has been called, the nearest node before the Iterator is chosen as the new reference node. Suppose we remove the "D" node, starting from the following state: A B C [D] * F G H I The "C" node becomes the new reference node, since it is the nearest node to the Iterator that is before the Iterator: A B [C] * F G H I If the reference node is after the Iterator, which is usually the case after previousNode() has been called, the nearest node after the Iterator is chosen as the new reference node. Suppose we remove "E", starting from the following state: A B C D * [E] F G H I The "F" node becomes the new reference node, since it is the nearest node to the Iterator that is after the Iterator: A B C D * [F] G H I Moving a node is equivalent to a removal followed by an insertion. Suppose we wish to move the "D" node to the end of the list, starting from the following state: A B C [D] * F G H I C The resulting state is as follows: A B [C] * F G H I D One special case arises when the reference node is the last node in the list and the reference node is removed. Suppose we remove node "C", starting from the following state: A B * [C] According to the rules we have given, the new reference node should be the nearest node after the Iterator, but there are no further nodes after "C". If there is no node in the original direction of the reference node, the nearest node in the opposite direction is selected as the reference node: A [B] * If the Iterator is part of a block of nodes that is removed, the above rules clearly indicate what is to be done. For instance, suppose "C" is the parent node of "D", "E", and "F", and we remove "C", starting with the following state: A B C [D] * E F G H I D The resulting state is as follows: A [B] * G H I D 7.1.1.3. Visibility of Nodes The underlying data structure that is being iterated may contain nodes that are not part of the logical view, and therefore will not be returned by the Iterator. If invisible nodes are present, nextNode() returns the next visible node, skipping over nodes that are to be excluded because of the value of the whatToShow flag. If a filter is present, it is applied before returning a node; if the filter rejects a node, the process is repeated until a node is accepted by the filter. That node is returned. If no visible nodes are encountered, a null is returned and the Iterator is positioned at the end of the list. In this case, the reference node is the last node in the list, whether or not it is visible. The same approach is taken, in the opposite direction, for previousNode(). In the following examples, we will use lower case letters to represent nodes that are in the data structure, but which are not in the logical view. For instance, consider the following list: A [B] * c d E F G A call to nextNode() returns E and advances to the following position: A B c d [E] * F G Nodes that are not visible may nevertheless be used as reference nodes if a reference node is removed. Suppose node "E" is removed, started from the state given above. The resulting state is: A B c [d] * F G Suppose a new node "X", which is visible, is inserted before "d". The resulting state is: A B c X [d] * F G Note that a call to previousNode() now returns node X. It is important not to skip over invisible nodes when the reference node is removed, because there are cases, like the one just given above, where the wrong results will be returned. When "E" was removed, if the new reference node had been "B" rather than "d", calling previousNode() would not return "X". 7.1.2. Filters Filters allow the user to create objects that "filter out" nodes. Each filter contains a user-written function that looks at a node and determines whether or not it should be filtered out. To use a filter, you create an Iterator or a TreeWalker that uses the filter. The Iterator or TreeWalker applies the filter to each node, and if the filter rejects the node, the Iterator or TreeWalker skips over the node as though it were not present in the document. Filters need not know how to navigate the structure that contains the nodes on which they operate. 7.1.2.1. Using Filters A Filter contains one method named acceptNode(), which allows an Iterator or TreeWalker to pass a Node to a filter and ask whether it should be present in the logical view. The acceptNode() function returns one of three values to state how the Node should be treated. If acceptNode() returns FILTER_ACCEPT, the Node will be present in the logical view; if it returns FILTER_SKIP, the Node will not be present in the logical view, but the children of the Node may; if it returns FILTER_REJECT, neither the Node nor its descendants will be present in the logical view. Since Iterators present nodes as an ordered list, without hierarchy, FILTER_REJECT and FILTER_SKIP are synonyms for Iterators, skipping only the single current node. Consider a filter that accepts the named anchors in an HTML document. In HTML, an HREF can refer to any A element that has a NAME attribute. Here is a filter in Java that looks at a node and determines whether it is a named anchor: class NamedAnchorFilter implements NodeFilter { short acceptNode(Node n) { if (n instanceof Element) { Element e = (element)n; if (! e.getNodeName().equals("A")) return FILTER_SKIP; if (e.getAttributeNode("NAME") != null) { return FILTER_ACCEPT; } } return FILTER_SKIP; } } If the above Filter were to be used with only Iterators, it could have used FILTER_REJECT wherever FILTER_SKIP is used, and the behavior would not change. For TreeWalker, though, FILTER_REJECT would reject the children of any element that is not a named anchor, and since named anchors are always contained within other elements, this would have meant that no named anchors would be found. FILTER_SKIP rejects the given node, but continues to examine the children; therefore, the above filter will work with either an Iterator or a TreeWalker. To use this filter, the user would create an instance of the filter and create an Iterator using it: NamedAnchorFilter myFilter = new NamedAnchorFilter(); NodeIterator iter=(DocumentTraversal)document.creatNodeIterator(node, SHOW_ELEMENT, myFilter); 7.1.2.2. Filters and Exceptions When writing a Filter, users should avoid writing code that can throw an exception. However, because an implementation can not prevent users from doing so, it is important that the behavior of filters that throw an exception be well-defined. A TreeWalker or Iterator does not catch or alter an exception thrown by a filter, but lets it propagate up to the user's code. The following functions may invoke a Filter, and may therefore propagate an exception if one is thrown by a Filter: 1. NodeIterator.nextNode() 2. NodeIterator.previousNode() 3. TreeWalker.firstChild() 4. TreeWalker.lastChild() 5. TreeWalker.nextSibling() 6. TreeWalker.previousSibling() 7. TreeWalker.nextNode() 8. TreeWalker.previousNode() 9. TreeWalker.parentNode() 7.1.2.3. Filters and Document Mutation Well-designed Filters do not modify the underlying document structure, but a Filter implementation can not prevent a user from writing code that does modify the document structure. Filters do not provide any special processing to handle this case. For instance, if a Filter removes a node from a document, it can still accept the node, which means that the node may be returned by the Iterator or TreeWalker even though it is no longer in the document. In general, this may lead to inconsistent, confusing results, so we encourage users to write Filters that make no changes to document structures. 7.1.2.4. Filters and whatToShow flags Iterator and TreeWalker apply whatToShow flags before applying Filters. If a node is rejected by the active whatToShow flags, a Filter will not be called to evaluate that node. When a node is rejected by the active whatToShow flags, children of that node will still be considered, and Filters may be called to evaluate them. 7.1.3. TreeWalker The TreeWalker interface provides many of the same benefits as the Iterator interface. The main difference between these two interfaces is that the TreeWalker presents a tree-oriented view of the nodes in a subtree, and an Iterator presents a list-oriented view. In other words, an Iterator allows you to move forward or back, but a TreeWalker allows you to move to the parent of a node, to one of its children, or to a sibling. Using a TreeWalker is quite similar to navigation using the Node directly, and the navigation methods for the two interfaces are analogous. For instance, here is a function that walks over a tree of nodes in document order, taking separate actions when first entering a node and after processing any children: processMe(Node n) { nodeStartActions(n); for (Node child=n.firstChild(); child != null; child=child.nextSibling()) processMe(child); } nodeEndActions(n); } Doing the same thing using a TreeWalker is quite similar. There is one difference: since navigation on the TreeWalker changes the current position, the position at the end of the function has changed. A read/write attribute named currentNode allows the current node for a TreeWalker to be set. We will use this to ensure that the position of the TreeWalker is restored when this function is completed: processMe(TreeWalker tw) { Node n = tw.getCurrentNode(); nodeStartActions(tw); for (Node child=tw.firstChild(); child!=null; child=tw.nextSibling()) { processMe(tw); } tw.setCurrentNode(n); nodeEndActions(tw); } The advantage of using a TreeWalker instead of direct Node navigation is that the TreeWalker allows the user to choose an appropriate view of the tree. Flags may be used to show or hide comments or processing instructions, entities may be expanded or left as entity references. In addition, Filters may be used to present a custom view of the tree. Suppose a program needs a view of a document that shows which tables occur in each chapter, listed by chapter. In this view, only the chapter elements and the tables that they contain are seen. The first step is to write an appropriate filter: class TablesInChapters implements NodeFilter { short acceptNode(Node n) { if (n instanceof Element) { if (n.getNodeName().equals("CHAPTER")) return FILTER_ACCEPT; if (n.getNodeName().equals("TABLE")) return FILTER_ACCEPT; if (n.getNodeName().equals("SECT1") || n.getNodeName().equals("SECT2") || n.getNodeName().equals("SECT3") || n.getNodeName().equals("SECT4") || n.getNodeName().equals("SECT5") || n.getNodeName().equals("SECT6") || n.getNodeName().equals("SECT7")) return FILTER_SKIP; } return FILTER_REJECT; } } Now the program can create an instance of this Filter, create a TreeWalker that uses it, and pass this TreeWalker to our ProcessMe() function: TablesInChapters tablesInChapters = new TablesInChapters(); TreeWalker tw = someDocTraversal.createTreeWalker(root, SHOW_ELEMENT, tablesInChapters); processMe(tw); Without making any changes to the above ProcessMe() function, it now processes only the CHAPTER and TABLE elements. The programmer can write other filters or set other flags to choose different sets of nodes; if functions use TreeWalker to navigate, they will support any view of the document defined with a TreeWalker. 7.2. Formal Interface Definition Interface NodeIterator (introduced in DOM Level 2) NodeIterators are used to step through a set of nodes, e.g. the set of nodes in a NodeList, the document subtree governed by a particular node, the results of a query, or any other set of nodes. The set of nodes to be iterated is determined by the implementation of the NodeIterator. DOM Level 2 specifies a single NodeIterator implementation for document-order traversal of a document subtree. Instances of these iterators are created by calling DocumentTraversal.createNodeIterator(). Any Iterator that returns nodes may implement the NodeIterator interface. Users and vendor libraries may also choose to create Iterators that implement the NodeIterator interface.

Definition group Constants for whatToShow These are the available values for the whatToShow parameter. They are the same as the set of possible types for Node, and their values are derived by using a bit position corresponding to the value of NodeType for the equivalent node type. Defined Constants SHOW_ALL Show all nodes. SHOW_ELEMENT Show element nodes. Show attribute nodes. This is meaningful only when creating an Iterator with an attribute node as its root; in this case, it means that the attribute SHOW_ATTRIBUTE node will appear in the first position of the iteration. Since attributes are not part of the document tree, they do not appear when iterating over the document tree. SHOW_TEXT Show text nodes. SHOW_CDATA_SECTION Show CDATASection nodes. SHOW_ENTITY_REFERENCE Show Entity Reference nodes. Show Entity nodes. This is meaningful only when creating an Iterator with an Entity node as its root; in this case, it means that SHOW_ENTITY the Entity node will appear in the first position of the iteration.

SHOW_COMMENT Show Comment nodes. SHOW_DOCUMENT Show Document nodes. SHOW_DOCUMENT_TYPE Show DocumentType nodes. SHOW_DOCUMENT_FRAGMENT Show DocumentFragment nodes. Show Notation nodes. This is meaningful only when creating an Iterator with a Notation node as its root; in this case, it means that the Notation node will SHOW_NOTATION appear in the first position of the iteration. Since notations are not part of the document tree, they do not appear when iterating over the document tree. filter of type NodeFilter, readonly The filter used to screen nodes. expandEntityReferences of type boolean, readonly The value of this flag determines whether entity reference nodes are expanded. To produce a view of the document that has entity references expanded and does not expose the entity reference node itself, use the whatToShow flags to hide the entity reference node and set expandEntityReferences to true when creating the iterator. To produce a view of the document that has entity reference nodes but no entity expansion, use the whatToShow flags to show the entity reference node and set expandEntityReferences to true. Methods nextNode Returns the next node in the set and advances the position of the Iterator in the set. After a NodeIterator is created, the first call to nextNode() returns the first node in the set. Return Value Node The next Node in the set being iterated over, or null if there are no more members in that set. No Parameters No Exceptions previousNode Returns the previous node in the set and moves the position of the Iterator backwards in the set. Return Value Node The previous Node in the set being iterated over, or null if there are no more members in that set. No Parameters No Exceptions Interface NodeFilter (introduced in DOM Level 2) Filters are objects that know how to "filter out" nodes. If an Iterator or TreeWalker is given a filter, before it returns the next node, it applies the filter. If the filter says to accept the node, the Iterator returns it; otherwise, the Iterator looks for the next node and pretends that the node that was rejected was not there. The DOM does not provide any filters. Filter is just an interface that users can implement to provide their own filters. Filters do not need to know how to iterate, nor do they need to know anything about the data structure that is being iterated. This makes it very easy to write filters, since the only thing they have to know how to do is evaluate a single node. One filter may be used with a number of different kinds of Iterators, encouraging code reuse. IDL Definition // Introduced in DOM Level 2: interface NodeFilter { // Constants returned by acceptNode const short FILTER_ACCEPT = 1; const short FILTER_REJECT = 2; const short FILTER_SKIP = 3; short acceptNode(in Node n); }; Definition group Constants returned by acceptNode The following constants are returned by the acceptNode() method: Defined Constants Accept the node. Navigation methods defined FILTER_ACCEPT for Iterator or TreeWalker will return this node. Reject the node. Navigation methods defined for Iterator or TreeWalker will not return FILTER_REJECT this node. For TreeWalker, the children of this node will also be rejected. Iterators treat this as a synonym for FILTER_SKIP. Reject the node. Navigation methods defined for Iterator or TreeWalker will not return FILTER_SKIP this node. For both Iterator and Treewalker, the children of this node will still be considered. Methods acceptNode Test whether a specified node is visible in the logical view of a TreeWalker or NodeIterator. This function will be called by the implementation of TreeWalker and NodeIterator; it is not intended to be called directly from user code. Parameters Node n The node to check to see if it passes the filter or not. Return Value short a constant to determine whether the node is accepted, rejected, or skipped, as defined above. No Exceptions Interface TreeWalker (introduced in DOM Level 2) TreeWalker objects are used to navigate a document tree or subtree using the view of the document defined by its whatToShow flags and any filters that are defined for the TreeWalker. Any function which performs navigation using a TreeWalker will automatically support any view defined by a TreeWalker. Omitting nodes from the logical view of a subtree can result in a structure that is substantially different from the same subtree in the complete, unfiltered document. Nodes that are siblings in the TreeWalker view may be children of different, widely separated nodes in the original view. For instance, consider a Filter that skips all nodes except for Text nodes and the root node of a document. In the logical view that results, all text nodes will be siblings and appear as direct children of the root node, no matter how deeply nested the structure of the original document.

Document Object Model Range Editors Vidur Apparao, Netscape Communications Peter Sharpe, SoftQuad Software Inc. 8.1. Introduction A Range identifies a range of content in a Document, DocumentFragment or Attr. It is contiguous in the sense that it can be characterized as selecting all of the content between a pair of end-points. Note: In a text editor or a word processor, a user can make a selection by pressing down the mouse at one point in a document, moving the mouse to another point, and releasing the mouse. The resulting selection is contiguous and consists of the content between the two points. The term 'selecting' does not mean that every Range corresponds to a selection made by a GUI user; however, such a selection can be returned to a DOM user as a Range. The Range interface provides methods for accessing and manipulating the document tree at a higher level than similar methods in the Node interface. The expectation is that each of the methods provided by the Range interface for the insertion, deletion and copying of content can be directly mapped to a series of Node editing operations enabled by DOM Core. In this sense, the Range operations can be viewed as convenience methods that also enable the implementation to optimize common editing patterns. This chapter describes the Range interface, including methods for creating and moving a Range and methods for manipulating content with Ranges. 8.2. Definitions and Notation 8.2.1. Position This chapter refers to two different representations of a document: the text or source form that includes the document markup and the tree representation similar to the one described in the Introduction. A Range consists of two end-points corresponding to the start and the end of the Range. An end-point's position in a document or document fragment tree can be characterized by a node and an offset. The node is called the container of the end-point and of its position. The container and its ancestors are the ancestor containers of the end-point and of its position. The offset within the node is called the offset of the end-point and its position. If the container is an Attribute, Document, Document Fragment, Element or EntityReference node, the offset is within its child nodes list. If the container is a CharacterData, Comment or ProcessingInstruction node, the offset is within the 16-bit units contained by it. The end-points of a Range must have a common ancestor container which is either a Document, DocumentFragment or Attr node. That is, the content of a Range must be entirely within the subtree rooted by a single Document, DocumentFragment or Attr Node. This common ancestor container is known as the root container of the Range. The tree rooted by the root container is known as the Range's context tree. The container of an end-point of a Range must be an Element, Comment, ProcessingInstruction, EntityReference, CDATASection, Document, DocumentFragment, Attr, or Text node. None of the ancestor containers of the end-point of a Range can be a DocumentType, Entity or Notation node. In terms of the text representation of a document, the end-points of a Range can only be on token boundaries. That is, the end-point of the text range cannot be in the middle of a start- or end-tag of an element or within the name of an entity or character reference. A Range locates a contiguous portion of the content of the structure model. The relationship between locations in a text representation of the document and in the Node tree interface of the DOM is illustrated in the following diagram: --------------------------------------------------------------------- [Range Example] --------------------------------------------------------------------- Range Example --------------------------------------------------------------------- In this diagram, four different Ranges are illustrated. The end-points of each range are labelled with s# (the start of the range) and e# (the end of the range), where # is the number of the Range. For Range 2, the start is in the BODY element and is immediately after the H1 element and immediately before the P element, so its position is between the H1 and P children of BODY. The offset of an end-point whose container is not a Text node is 0 if it is before the first child, 1 if between the first and second child, and so on. So, for the start of the Range 2, the container is BODY and the offset is 1. The offset of an end-point whose container is a Text node is obtained similarly but using 16-bit unit positions instead. For example, the end-point labelled s1 of the Range 1 has a Text node (the one containing "Title") as its container and an offset of 2 since it is between the second and third 16-bit unit. Notice that the end-points of Ranges 3 and 4 correspond to the same location in the text representation. An important feature of the Range is that an end-point of a Range can unambiguously represent every position within the document tree. The containers and offsets of the end-points can be obtained through the following read-only Range attributes: readonly attribute Node startContainer; readonly attribute long startOffset; readonly attribute Node endContainer; readonly attribute long endOffset; If the end-points of a Range have the same containers and offsets, the Range is said to be a collapsed Range. (This is often referred to as an insertion point in a user agent.) 8.2.2. Selection and Partial Selection A node or 16-bit unit is said to be selected by a Range if it is between the two end-points of the Range, that is, if the position immediately before the node or 16-bit unit is before the end of the Range and the position immediately after the node or 16-bit unit is after the start of the range. For example, in terms of a text representation of the document, an element would be selected by a Range if its corresponding start-tag was located after the start of the Range and its end-tag was located before the end of the Range. In the examples in the above diagram, the Range 2 selects the P node and the Range 3 selects the text node containing the text "Blah xyz." A node is said to be partially selected by a Range if it is an ancestor container of exactly one end-point of the Range. For example, consider Range 1 in the above diagram. The element H1 is partially selected by that Range since the start of the Range is within one of its children. 8.2.3. Notation Many of the examples in this chapter are illustrated using a text representation of a document. The end-points of a range are indicated by displaying the characters (be they markup or data characters) between the two end-points in bold, as in ABCDEF When both end-points are at the same position, they are indicated with a bold caret ('^'), as in A^BCDEF And when referring to a single end-point, it will be shown as a bold asterisk ('*') as in A*BCDEF 8.3. Creating a Range A range is created by calling the createRange() method on the DocumentRange interface. This interface can be obtained from the object implementing the Document interface using binding-specific casting methods. interface DocumentRange { Range createRange(); } The initial state of the range returned from this method is such that both of its end-points are positioned at the beginning of the corresponding Document, before any content. In other words, the container of each end-point is the Document node and the offset within that node is 0. Like some objects created using methods in the Document interface (such as Nodes and DocumentFragments), Ranges created via a particular document instance can select only content associated with that Document, or with DocumentFragments and Attrs for which that Document is the ownerDocument. Such Ranges, then, can not be used with other Document instances. 8.4. Changing a Range's Position A Range's position can be specified by setting the container and offset of each end-point with the setStart and setEnd methods. void setStart(in Node parent, in long offset) raises(RangeException); void setEnd(in Node parent, in long offset) raises(RangeException); If one end-point of a Range is set to have a root container other than the current one for the range, the range is collapsed to the new position. This enforces the restriction that both end-points of a Range must have the same root container. The start position of a Range is guaranteed to never be after the end position. To enforce this restriction, if the start is set to be at a position after the end, the range is collapsed to that position. Similarly, if the end is set to be at a position before the start, the range is collapsed to that position. It is also possible to set a Range's position relative to nodes in the tree: void setStartBefore(in Node node); raises(RangeException); void setStartAfter(in Node node); raises(RangeException); void setEndBefore(in Node node); raises(RangeException); void setEndAfter(in Node node); raises(RangeException); The parent of the node becomes the container of the end-point and the Range is subject to the same restrictions as given above in the description of setStart() and setEnd(). A Range can be collapsed to either end-point: void collapse(in boolean toStart); Passing TRUE as the parameter toStart will collapse the Range to its start , FALSE to its end. Testing whether a Range is collapsed can be done by examining the isCollapsed attribute: readonly attribute boolean isCollapsed; The following methods can be used to make a range select the contents of a node or the node itself. void selectNode(in Node n); void selectNodeContents(in Node n); The following examples demonstrate the operation of the methods selectNode and selectNodeContents: Before: ^ABC After range.selectNodeContents(FOO): ABC After range.selectNode(FOO): ABC 8.5. Comparing Range End-Points It is possible to compare two Ranges by comparing their end-points: int compareEndPoints(in CompareHow how, in Range sourceRange) raises(RangeException); where CompareHow is one of four values: StartToStart, StartToEnd, EndToEnd and EndToStart. The return value is -1, 0 or 1 depending on whether the corresponding end-point of the Range is before, equal to, or after the corresponding end-point of sourceRange. An exception is thrown if the two Ranges have different root containers. The result of comparing two end-points (or positions) is specified below. An informal but not always correct specification is that an end-point is before, equal to, or after another if it corresponds to a location in a text representation before, equal to, or after the other's corresponding location. Let A and B be two end-points or positions. Then one of the following holds: A is before B, A is equal to B, or A is after B. Which one holds is specified in the following by examining four cases: In the first case the end-points have the same container. A is before B if its offset is less than the offset of B, A is equal to B if its offset is equal to the offset of B, and A if after B if its offset is greater than the offset of B. In the second case a child C of the container of A is an ancestor container of B. In this case, A is before B if the offset of A is less than or equal to the index of the child C and A is after B otherwise. In the third case a child C of the container of B is an ancestor container of A. In this case, A is before B if the index of the child C is less than the offset of B and A is after B otherwise. In the fourth case, none of three other cases hold: the containers of A and B are siblings or descendants of sibling nodes. In this case, A is before B if the container of A is before the container of B in a pre-order traversal of the Ranges' context tree and A is after B otherwise. Note that because the same location in a text representation of the document can correspond to two different positions in the DOM tree, it is possible for two end-points to not compare equal even though they would be equal in the text representation. For this reason, the informal definition above can sometimes be incorrect. 8.6. Deleting Content with a Range One can delete the contents selected by a Range with: void deleteContents(); deleteContents() deletes all nodes and characters selected by the Range. All other nodes and characters remain in the context tree of the Range. Some examples of this deletion operation are: (1) ABCDCD --> A^CD (2) ABCDE --> AB^E (3) XYZWQ --> X^WQ (4) ABCD --> A^D After deleteContents() is invoked on a Range, the Range is collapsed. If no node was partially selected by the Range, then it is collapsed to its original start point, as in example (1). If a node was partially selected by the Range and was an ancestor container of the start of the Range and no ancestor of the node satisfies these two conditions, then the Range is collapsed to the position immediately after the node, as in examples (2) and (4). If a node waspartially selected by the Range and was an ancestor container of the end of the Range and no ancestor of the node satisfies these two conditions, then the Range is collapsed to the position immediately before the node, as in examples (3) and (4). 8.7. Extracting Content If the contents of a range need to be extracted rather than deleted, the following method may be used: DocumentFragment extractContents(); The extractContents() method removes nodes from the Range's context tree similarly to the deleteContents() method. In addition, it places the deleted contents in a new DocumentFragment. The following examples illustrate the contents of the returned document fragment: (1) ABCDCD --> BCD (2) ABCDE --> CD (3) XYZWQ --> YZ (4) ABCD --> BC It is important to note that nodes that are partially selected by the range are cloned. Since part of such a node's contents must remain in the Range's context tree and part of the contents must be moved to the new fragment, a clone of the partially selected node is included in the new fragment. Note that cloning does not take place for selected elements; these nodes are moved to the new fragment. 8.8. Cloning Content The contents of a range may be duplicated using the following method: DocumentFragment cloneContents(); This method returns a DocumentFragment that is similar to the one returned by the method extractContents(). However, in this case, the original nodes and character data in the Range are not removed from the Range's context tree. Instead, all of the nodes and text content within the returned DocumentFragment are cloned. 8.9. Inserting Content A node may be inserted into a range using the following method: void insertNode(in Node n) raises(RangeException); The insertNode() method inserts the specified node into the Range's context tree. For this method, the end of the range is ignored and the node is inserted at the start of the range. The Node passed into this method can be a DocumentFragment. In that case, the contents of the fragment are inserted at the start position of the range, but the fragment itself is not. Note that if the Node represents the root of a sub-tree, the entire sub-tree is inserted. The same rules that apply to the insertBefore() method on the Node interface apply here. Specifically, the Node passed in, if it is already has a parent, will be removed from its existing position. 8.10. Surrounding Content The insertion of a single node to subsume the content selected by a Range can be performed with: void surroundContents(in Node n); The surroundContents() method causes all of the content selected by the range to be rooted by the specified node. Calling surroundContents() with the node FOO in the following examples yields: Before: ABCDE After surroundContents(FOO): ABCDE Another way of of describing the effect of this method on the Range's context tree is to decompose it in terms of other operations: 1. Remove the contents selected by the range with a call to extractContents(). 2. Insert node where the range is now collapsed (after the extraction) with insertNode() 3. Insert the entire contents of the extracted fragment into node. Specifically, invoke the appendChild() on node passing in the DocumentFragment returned as a result of the call to extractContents() 4. Select node and all of its contents with selectNode(). The surroundContents() method raises an exception if the range partially selects a non-Text node. An example of a range for which surroundContents() raises an exception is: ABCDE If node has any children, those children are removed before its insertion. Also, if node already has a parent, it is removed from the original parent's childNodes list. 8.11. Miscellaneous Members One can clone a Range: Range cloneRange(); This creates a new Range which selects exactly the same content as that selected by the Range on which the method cloneRange was invoked. No content is affected by this operation. Because the end-points of a range do not necessarily have the same containers, use: readonly attribute Node commonAncestorContainer; to get the ancestor container of both end-points that is furthest down from the Range's root container One can get a copy of all the character data selected or partially selected by a range with: DOMString toString(); This does nothing more than simply concatenate all the character data selected by the range. This includes character data in both Text and CDATASection nodes. 8.12. Range modification under document mutation As a document is modified, the Ranges within the document need to be updated. For example, if one end-point of a Range is within a node and that node is removed from the document, then the Range would be invalid unless it is fixed up in some way. This section describes how Ranges are modified under document mutations so that they remain valid. There are two general principles which apply to Ranges under document mutation: The first is that all Ranges in a document will remain valid after any mutation operation and the second is that, as much as possible, all Ranges will select the same portion of the document after any mutation operation. Any mutation of the document tree which affect Ranges can be considered to be a combination of basic delete and insertion operations. In fact, it can be convenient to think of those operations as being accomplished using the deleteContents() and insertNode() Range methods. 8.12.1. Insertions An insertion occurs at a single point, the insertion point, in the document. For any Range in the document tree, consider each end-point. The only case in which the end-point will be changed after the insertion is when the end-point and the insertion point have the same container and the offset of the insertion point is strictly less than the offset of the Range's end-point. In that case the offset of the Range's end-point will be increased so that it is between the same nodes or characters as it was before the insertion. Note that when content is inserted at an end-point, it is ambiguous as to where the end-point should be repositioned if its relative position is to be maintained. This is not the same as the principle, given above, of having the Range select the same content, although often the Range ends up selecting the same content.There are two possibilities: at the start or at the end of the newly inserted content. We have chosen that in this case neither the container nor offset of the end-point is changed. As a result, it will be positioned at the start of the newly inserted content. Examples: Suppose the Range selects the following:

Abcd efgh XY blah ijkl

Consider the insertion of the text "inserted text" at the following positions: 1. Before the 'X':

Abcd efgh inserted textXY blah ijkl

2. After the 'X':

Abcd efgh Xinserted textY blah ijkl

3. After the 'Y':

Abcd efgh XYinserted text blah ijkl

4. After the 'h' in "Y blah":

Abcd efgh XY blahinserted text ijkl

8.12.2. Deletions Any deletion from the document tree can be considered as a sequence of deleteContents() operations applied to a minimal set of disjoint Ranges. To specify how a Range is modified under deletions we need only to consider what happens to a Range only under a single deleteContents() operation of another Range. And, in fact, we need only to consider what happens to a single end-point of the Range since both end-points are modified using the same algorithm. If an end-point is within the content being deleted, then after the deletion it will be at the same position as the one common to the end-points of the Range used to delete the contents. If an end-point is after the content being deleted then it is not affected by the deletion unless its container is also the container of one of the end-points of the range being deleted. If there is such a common container, then the index of the end-point is modified so that the end-point maintains its position relative to the content of the container. If an end-point is before the content being deleted then it is not affected by the deletion at all. Examples: In these examples, the Range on which deleteContents() is invoked is indicated by the underline. Example 1. Before:

Abcd efgh The Range ijkl

After:

Abcd Range ijkl

Example 2. Before:

Abcd efgh The Range ijkl

Sutor, IBM Research (for DOM Level 1) Several of the following term definitions have been borrowed or modified from similar definitions in other W3C or standards documents. See the links within the definitions for more information. 16-bit unit The base unit of a DOMString. Since a DOMString is a UTF-16 encoded string, a single character reference may correspond to one or two 16-bit units. ancestor An ancestor node of any node A is any node above A in a tree model of a document, where "above" means "toward the root." API An API is an application programming interface, a set of functions or methods used to access some functionality. child A child is an immediate descendant node of a node. client application A [client] application is any software that uses the Document Object Model programming interfaces provided by the hosting implementation to accomplish useful work. Some examples of client applications are scripts within an HTML or XML document. COM COM is Microsoft's Component Object Model [COM], a technology for building applications from binary software components. content model The content model is a simple grammar governing the allowed types of the child elements and the order in which they appear. See Element Content in XML [XML]. context A contextspecifies an access pattern (or path): a set of interfaces which give you a way to interact with a model. For example, imagine a model with different colored arcs connecting data nodes. A context might be a sheet of colored acetate that is placed over the model allowing you a partial view of the total information in the model. convenience A convenience method is an operation on an object that could be accomplished by a program consisting of more basic operations on the object. Convenience methods are usually provided to make the API easier and simpler to use or to allow specific programs to create more optimized implementations for common operations. A similar definition holds for a convenience property. cooked model A model for a document that represents the document after it has been manipulated in some way. For example, any combination of any of the following transformations would create a cooked model: 1. Expansion of internal text entities. 2. Expansion of external entities. 3. Model augmentation with style-specified generated text. 4. Execution of style-specified reordering. 5. Execution of scripts. A browser might only be able to provide access to a cooked model, while an editor might provide access to a cooked or the initial structure model (also known as the uncooked model) for a document. CORBA CORBA is the Common Object Request Broker Architecture from the OMG [CORBA]. This architecture is a collection of objects and libraries that allow the creation of applications containing objects that make and receive requests and responses in a distributed environment. cursor A cursoris an object representation of a node. It may possess information about context and the path traversed to reach the node. data model A data model is a collection of descriptions of data structures and their contained fields, together with the operations or functions that manipulate them. deprecation When new releases of specifications are released, some older features may be marked as being deprecated. This means that new work should not use the features and that although they are supported in the current release, they may not be supported or available in future releases. descendant A descendant node of any node A is any node below A in a tree model of a document, where "above" means "toward the root." DOM Level 0 The term "DOM Level 0" refers to a mix (not formally specified) of HTML document functionalities offered by Netscape Navigator version 3.0 and Microsoft Internet Explorer version 3.0. In some cases, attributes or methods have been included for reasons of backward compatibility with "DOM Level 0". ECMAScript The programming language defined by the ECMA-262 standard [ECMAScript]. As stated in the standard, the originating technology for ECMAScript was JavaScript [JavaScript]. Note that in the ECMAScript binding, the word "property" is used in the same sense as the IDL term "attribute." element Each document contains one or more elements, the boundaries of which are either delimited by start-tags and end-tags, or, for empty elements by an empty-element tag. Each element has a type, identified by name, and may have a set of attributes. Each attribute has a name and a value. See Logical Structures in XML [XML]. event propagation, also known as event bubbling This is the idea that an event can affect one object and a set of related objects. Any of the potentially affected objects can block the event or substitute a different one (upward event propagation). The event is broadcast from the node at which it originates to every parent node. equivalence Two nodes are equivalent if they have the same node type and same node name. Also, if the nodes contain data, that must be the same. Finally, if the nodes have attributes then collection of attribute names must be the same and the attributes corresponding by name must be equivalent as nodes. Two nodes are deeply equivalent if they are equivalent, the child node lists are equivalent are equivalent as NodeList objects, and the pairs of equivalent attributes must in fact be deeply equivalent. Two NodeList objects are equivalent if they have the same length, and the nodes corresponding by index are deeply equivalent. Two NamedNodeMap objects are equivalent if they are have the same length, they have same collection of names, and the nodes corresponding by name in the maps are deeply equivalent. Two DocumentType nodes are equivalent if they are equivalent as nodes, have the same names, and have equivalent entities and attributes NamedNodeMap objects. hosting implementation A [hosting] implementation is a software module that provides an implementation of the DOM interfaces so that a client application can use them. Some examples of hosting implementations are browsers, editors and document repositories. HTML The HyperText Markup Language (HTML) is a simple markup language used to create hypertext documents that are portable from one platform to another. HTML documents are SGML documents with generic semantics that are appropriate for representing information from a wide range of applications. [HTML4.0] IDL An Interface Definition Language (IDL) is used to define the interfaces for accessing and operating upon objects. Examples of IDLs are the Object Management Group's IDL [CORBA], Microsoft's IDL [MIDL], and Sun's Java IDL [JavaIDL]. implementor Companies, organizations, and individuals that claim to support the Document Object Model as an API for their products. inheritance In object-oriented programming, the ability to create new classes (or interfaces) that contain all the methods and properties of another class (or interface), plus additional methods and properties. If class (or interface) D inherits from class (or interface) B, then D is said to be derived from B. B is said to be a base class (or interface) for D. Some programming languages allow for multiple inheritance, that is, inheritance from more than one class or interface. initial structure model Also known as the raw structure model or the uncooked model, this represents the document before it has been modified by entity expansions, generated text, style-specified reordering, or the execution of scripts. In some implementations, this might correspond to the "initial parse tree" for the document, if it ever exists. Note that a given implementation might not be able to provide access to the initial structure model for a document, though an editor probably would. interface An interface is a declaration of a set of methods with no information given about their implementation. In object systems that support interfaces and inheritance, interfaces can usually inherit from one another. language binding A programming language binding for an IDL specification is an implementation of the interfaces in the specification for the given language. For example, a Java language binding for the Document Object Model IDL specification would implement the concrete Java classes that provide the functionality exposed by the interfaces. local name A local name is the local part of a qualified name. This is called the local part in Namespaces in XML [Namespaces]. method A method is an operation or function that is associated with an object and is allowed to manipulate the object's data. model A model is the actual data representation for the information at hand. Examples are the structural model and the style model representing the parse structure and the style information associated with a document. The model might be a tree, or a directed graph, or something else. namespace prefix A namespace prefix is a string that associates an element or attribute name with a namespace URI in XML. See namespace prefix in Namespaces in XML [Namespaces]. namespace URI A namespace URI is a URI that identifies an XML namespace. This is called the namespace name in Namespaces in XML [Namespaces]. object model An object model is a collection of descriptions of classes or interfaces, together with their member data, member functions, and class-static operations. parent A parent is an immediate ancestor node of a node. qualified name A qualified name is the name of an element or attribute defined as the concatenation of a local name (as defined in this specification), optionally preceded by a namespace prefix and colon character. See Qualified Names in Namespaces in XML [Namespaces]. root node The root node is the unique node that is not a child of any other node. All other nodes are children or other descendents of the root node. See Well-Formed XML Documents in XML [XML]. sibling Two nodes are siblings if they have the same parent node. string comparison When string matching is required, it is to occur as though the comparison was between 2 sequences of code points from the Unicode 2.0 standard. tag valid document A document is tag valid if all begin and end tags are properly balanced and nested. type valid document A document is type valid if it conforms to an explicit DTD. uncooked model See initial structure model. well-formed document A document is well-formed if it is tag valid and entities are limited to single elements (i.e., single sub-trees). XML Extensible Markup Language (XML) is an extremely simple dialect of SGML which is completely described in this document. The goal is to enable generic SGML to be served, received, and processed on the Web in the way that is now possible with HTML. XML has been designed for ease of implementation and for interoperability with both SGML and HTML. [XML] XML namespace An XML namespace is a collection of names, identified by a URI reference [RFC2396], which are used in XML documents as element types and attribute names.
