The Document Object Model provides a standard set of objects for representing HTML and XML documents, a standard model of how these objects can be combined, and a standard interface for accessing and manipulating them. Vendors can support the DOM as an interface to their proprietary data structures and APIs, and content authors can write to the standard DOM interfaces rather than product-specific APIs, thus increasing interoperability on the Web. The goal of the DOM specification is to define a programmatic interface for XML and HTML. The DOM Level 1 specification is separated into two parts: Core and HTML. The Core DOM Level 1 section provides a low-level set of fundamental interfaces that can represent any structured document, as well as defining extended interfaces for representing an XML document. These extended XML interfaces need not be implemented by a DOM implementation that only provides access to HTML documents; all of the fundamental interfaces in the Core section must be implemented. A compliant DOM implementation that implements the extended XML interfaces is required to also implement the fundamental Core interfaces, but not the HTML interfaces. The HTML Level 1 section provides additional, higher-level interfaces that are used with the fundamental interfaces defined in the Core Level 1 section to provide a more convenient view of an HTML document. A compliant implementation of the HTML DOM implements all of the fundamental Core interfaces as well as the HTML interfaces. Status of this document This document is a version of the DOM Level 1 Recommendation incorporating the errata changes as of September 29, 2000. It is released by the DOM Working Group as a W3C Working Draft to gather public feedback before its final release as the DOM Level 1 second edition W3C Recommendation (as these changes are editorials, there will be no Candidate Recommendation or Proposed Recommendation stages). The review period for this Working Draft is 4 weeks ending October 27 2000. This second edition is not a new version of the DOM Level 1; it merely incorporates the changes dictated by the first-edition errata list. This document should not be used as reference material or cited as a normative reference from another document. 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.

Editors Jonathan Robie, Texcel Research Introduction The Document Object Model (DOM) is an application programming interface (API) for valid HTML and well-formed 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 Object Management Group (OMG) IDL [OMGIDL], as defined in the CORBA 2.2 specification [CORBA]. In addition to the OMG IDL specification, we provide language bindings for Java [Java] and ECMAScript [ECMAScript] (an industry-standard scripting language based on JavaScript and JScript). 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, which 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 also use the term "tree" when referring to the arrangement of those information items which can be reached by using "tree-walking" methods; (this does not include attributes). 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]. Note: There may be some variations depending on the parser being used to build the DOM. For instance, the DOM may not contain whitespaces in element content if the parser discards them. 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. * Although the Document Object Model was strongly influenced by "Dynamic HTML", in Level 1, it does not implement all of "Dynamic HTML". In particular, events have not yet been defined. Level 1 is designed to lay a firm foundation for this kind of functionality by providing a robust, flexible model of the document itself. * The Document Object Model is not a binary specification. DOM programs written in the same language binding 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 in 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 1 currently consists of two parts, DOM Core and DOM HTML. 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. A DOM application can use the hasFeature method of the DOMImplementation interface to determine whether the module is supported or not. The feature strings for all modules in DOM Level 1 are listed in the following table; (strings are case-insensitive): ModuleFeature String XML XML HTML HTML 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 cannot know what constructors to call for an implementation. In general, DOM users call the createX() 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 createX() functions. Limitations of Level 1 The DOM Level 1 specification is intentionally limited to those methods needed to represent and manipulate document structure and content. The plan is for future Levels of the DOM specification to provide: 1. A structure model for the internal subset and the external subset. 2. Validation against a schema. 3. Control for rendering documents via style sheets. 4. Access control. 5. Thread-safety. 6. Events. 29 September, 2000 1.

Overview of the DOM Core Interfaces This section defines a 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. For XML and HTML, the node types, and which node types they may have as children, are as follows: * Document -- Element (maximum of one), ProcessingInstruction, Comment, DocumentType (maximum of one) * 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 implementation need only expose methods with the defined names and specified operation, not 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. In the DOM Level 1, 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 1 API does not define a standard way to create DOMImplementation or Document objects; 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 bindings 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 Working Group. 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 make it difficult to avoid naming conflicts with short, familiar names. So, some 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 [Unicode] and Amendment 1 of [ISO/IEC 10646]). The UTF-16 encoding was chosen because of its widespread industry practice. 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 negotiation to decide the width and encoding of a character. 1.1.6. String comparisons 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. In addition, the DOM assumes that any case normalizations take place in the processor, before the DOM structures are built. Note: Besides case folding, there are additional normalizations that can be applied to text. The W3C I18N Working Group is in the process of defining exactly which normalizations are necessary, and where they should be applied. The W3C I18N Working Group expects to require early normalization, which means that data read into the DOM is assumed to already be normalized. The DOM and applications built on top of it in this case only have to assure that text remains normalized when being changed. For further details, please see [Charmod]. 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 situations, 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.

The DOM Level 1 does not specify a way of creating a document instance, and hence document creation is an operation specific to an implementation. Future Levels of the DOM specification are expected to provide methods for creating documents directly. IDL Definition interface DOMImplementation { boolean hasFeature(in DOMString feature, in DOMString version); }; Methods hasFeature Test if the DOM implementation implements a specific feature. Parameters feature of type DOMString The name of the feature to test (case-insensitive). The values used by DOM features are defined throughout this specification and listed in the Compliance section. The name must be an XML name. To avoid possible conflicts, as a convention, names referring to features defined outside the DOM specification should be made unique by reversing the name of the Internet domain name of the person (or the organization that the person belongs to) who defines the feature, component by component, and using this as a prefix. For instance, the W3C SYMM Working Group defines the feature "org.w3c.dom.smil". version of type DOMString This is the version number of the feature to test. In Level 1, this is the string "1.0". If the version is not specified, supporting any version of the feature causes the method to return true. Return Value boolean true if the feature is implemented in the specified version, false otherwise. No Exceptions 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); }; 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 1 does not support editing the Document Type Declaration. docType cannot be altered in any way, including through the use of methods inherited from the Node interface, such as insertNode or removeNode. 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". implementation of type DOMImplementation, readonly The DOMImplementation object that handles this document. A DOM application may use objects from multiple implementations. Methods createAttribute Creates an Attr of the given name. Note that the Attr instance can then be set on an Element using the setAttributeNode method. Parameters name of type DOMString The name of the attribute. Return Value Attr A new Attr object with the NodeName attribute set to name. The value of the attribute is the empty string. Exceptions DOMException INVALID_CHARACTER_ERR: Raised if the specified name contains an illegal character. createCDATASection Creates a CDATASection node whose value is the specified string. Parameters data of type DOMString 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. createComment Creates a Comment node given the specified string. Parameters data of type DOMString The data for the node. Return Value Comment The new Comment object. No Exceptions createDocumentFragment Creates an empty DocumentFragment object. Return Value DocumentFragment A new DocumentFragment. No Parameters No Exceptions 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. Parameters tagName of type DOMString 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 with the nodeName attribute set to tagName. Exceptions DOMException INVALID_CHARACTER_ERR: Raised if the specified name contains an illegal character. createEntityReference Creates an EntityReference object. In addition, if the referenced entity is known, the child list of the EntityReference node is made the same as that of the corresponding Entity node. Parameters name of type DOMString 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 illegal character. NOT_SUPPORTED_ERR: Raised if this document is an HTML document. createProcessingInstruction Creates a ProcessingInstruction node given the specified name and data strings. Parameters target of type DOMString The target part of the processing instruction. data of type DOMString The data for the node. Return Value ProcessingInstruction The new ProcessingInstruction object. Exceptions DOMException INVALID_CHARACTER_ERR: Raised if the specified target contains an illegal character. NOT_SUPPORTED_ERR: Raised if this document is an HTML document. createTextNode Creates a Text node given the specified string. Parameters data of type DOMString The data for the node. Return Value Text The new Text object. No Exceptions getElementsByTagName Returns a NodeList of all the Elements with a given tag name in the order in which they are encountered in a preorder traversal of the Document tree. Parameters tagname of type DOMString 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 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.

Note: Numeric codes up to 200 are reserved to W3C for possible future use. Defined Constants ATTRIBUTE_NODE The node is an Attr. CDATA_SECTION_NODE The node is a CDATASection. COMMENT_NODE The node is a Comment. DOCUMENT_FRAGMENT_NODE The node is a DocumentFragment. DOCUMENT_NODE The node is a Document. DOCUMENT_TYPE_NODE The node is a DocumentType. ELEMENT_NODE The node is an Element. ENTITY_NODE The node is an Entity. ENTITY_REFERENCE_NODE The node is an EntityReference. NOTATION_NODE The node is a Notation. PROCESSING_INSTRUCTION_NODE The node is a ProcessingInstruction. TEXT_NODE The node is a Text node. The values of nodeName, nodeValue, and attributes vary according to the node type as follows: nodeName nodeValue attributes Attr name of attribute value of null attribute CDATASection #cdata-section content of null the CDATA Section Comment #comment content of null the comment Document #document null null DocumentFragment #document-fragment null null DocumentType document type name null null Element tag name null NamedNodeMap Entity entity name null null EntityReference name of entity null null referenced Notation notation name null null ProcessingInstructiontarget entire null content excluding the target Text #text content of null the text node Attributes attributes of type NamedNodeMap, readonly A NamedNodeMap containing the attributes of this node (if it is an Element) or null otherwise. 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. 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. nextSibling of type Node, readonly The node immediately following this node. If there is no such node, this returns null. nodeName of type DOMString, readonly The name of this node, depending on its type; see the table above. nodeType of type unsigned short, readonly A code representing the type of the underlying object, as defined 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. ownerDocument of type Document, readonly The Document object associated with this node. This is also the Document object used to create new nodes. When this node is a Document, this is null. 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. previousSibling of type Node, readonly The node immediately preceding this node. If there is no such node, this returns null. Methods 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 newChild of type Node 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. cloneNode Returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes. The duplicate node has no parent; (parentNode is 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 an Attribute directly, as opposed to be cloned as part of an Element cloning operation, returns a specified attribute (specified is true). Cloning any other type of node simply returns a copy of this node. Note that cloning an immutable subtree results in a mutable copy, but the children of an EntityReference clone are readonly. In addition, clones of unspecified Attr nodes are specified. And, cloning Document, DocumentType, Entity, and Notation nodes is implementation dependent. Parameters deep of type boolean 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. Exceptions DOMException NOT_SUPPORTED_ERR: Raised if this node is a of type DOCUMENT_NODE, DOCUMENT_TYPE_NODE, ENTITY_NODE, or NOTATION_NODE and the implementation does not support cloning this type of node. 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 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 newChild of type Node The node to insert. refChild of type Node 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 or if the parent of the node being inserted is readonly. NOT_FOUND_ERR: Raised if refChild is not a child of this node. removeChild Removes the child node indicated by oldChild from the list of children, and returns it. Parameters oldChild of type Node 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. replaceChild Replaces the child node oldChild with newChild in the list of children, and returns the oldChild node. If newChild is a DocumentFragment object, oldChild is replaced by all of the DocumentFragment children, which are inserted in the same order. If the newChild is already in the tree, it is first removed. Parameters newChild of type Node The new node to put in the child list. oldChild of type Node 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 or the parent of the new node is readonly. NOT_FOUND_ERR: Raised if oldChild is not a child of this node. Interface NodeList The NodeList interface provides the abstraction of an ordered collection of nodes, without defining or constraining how this collection is implemented. NodeList objects in the DOM are live. 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 index of type unsigned long 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; }; NamedNodeMap objects in the DOM are live. Attributes length of type unsigned long, readonly The number of nodes in this map. The range of valid child node indices is 0 to length-1 inclusive. Methods getNamedItem Retrieves a node specified by name. Parameters name of type DOMString The nodeName of a node to retrieve. Return Value Node A Node (of any type) with the specified nodeName, or null if it does not identify any node in this map. No Exceptions item Returns the indexth item in the map. If index is greater than or equal to the number of nodes in this map, this returns null. Parameters index of type unsigned long Index into this map. Return Value Node The node at the indexth position in the map, or null if that is not a valid index. No Exceptions removeNamedItem Removes a node specified by name. When this map contains the attributes attached to an element, if the removed attribute is known to have a default value, an attribute immediately appears containing the default value. Parameters name of type DOMString The nodeName of the node to remove. Return Value Node The node removed from this map if a node with such a name exists. Exceptions DOMException NOT_FOUND_ERR: Raised if there is no node named name in this map. NO_MODIFICATION_ALLOWED_ERR: Raised if this map is readonly. setNamedItem Adds a node using its nodeName attribute. If a node with that name is already present in this map, it is replaced by the new one. 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 arg of type Node A node to store in this map. The node will later be accessible using the value of its nodeName attribute. Return Value Node If the new Node replaces an existing node the replaced 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 this map. NO_MODIFICATION_ALLOWED_ERR: Raised if this map 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. 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. As explained in the DOMString interface, text strings in the DOM are represented in UTF-16, i.e. as a sequence of 16-bit units. In the following, the term 16-bit units is used whenever necessary to indicate that indexing on CharacterData is done in 16-bit units. 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 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 arg of type DOMString The DOMString to append. Exceptions DOMException 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 offset of type unsigned long The offset from which to start removing. count of type unsigned long 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 insertData Insert a string at the specified 16-bit unit offset. Parameters offset of type unsigned long The character offset at which to insert. arg of type DOMString 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 replaceData Replace the characters starting at the specified 16-bit unit offset with the specified string. Parameters offset of type unsigned long The offset from which to start replacing. count of type unsigned long 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). arg of type DOMString 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 substringData Extracts a range of data from the node. Parameters offset of type unsigned long Start offset of substring to extract. count of type unsigned long 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. 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; // Modified in DOM Level 1: attribute DOMString value; // raises(DOMException) on setting }; 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. + If the attribute is not associated to any element (i.e. because it was just created or was obtained from some removal or cloning operation) specified is true. value of type DOMString, modified in DOM Level 1 On retrieval, the value of the attribute is returned as a string. Character and general entity references are replaced with their values. See also the method getAttribute on the Element interface. On setting, this creates a Text node with the unparsed contents of the string. I.e. any characters that an XML processor would recognize as markup are instead treated as literal text. See also the method setAttribute on the Element interface. Exceptions on setting DOMException NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly. Interface Element The Element interface represents an element in an HTML or XML document. 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(); }; 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 name of type DOMString 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 getAttributeNode Retrieves an Attr node by name. Parameters name of type DOMString 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 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 name of type DOMString 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, including attribute nodes, 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 [XPointer] lookups) that depend on a particular document tree structure are to be used. Note: In cases where the document contains CDATASections, the normalize operation alone may not be sufficient, since XPointers do not differentiate between Text nodes and CDATASection nodes. No Parameters No Return Value No Exceptions 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 name of type DOMString The name of the attribute to remove. Exceptions DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly. No Return Value removeAttributeNode Removes the specified attribute. If the removed Attr has a default value it is immediately replaced. Parameters oldAttr of type Attr The Attr node to remove from the attribute list. 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. 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 name of type DOMString The name of the attribute to create or alter. value of type DOMString Value to set in string form. Exceptions DOMException INVALID_CHARACTER_ERR: Raised if the specified name contains an illegal character. NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly. No Return Value setAttributeNode Adds a new attribute node. If an attribute with that name is already present in the element, it is replaced by the new one. Parameters newAttr of type Attr The Attr node to add to the attribute list. Return Value Attr If the newAttr attribute replaces an existing attribute, the replaced 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. 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 the information items (elements, comments, etc.) 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. IDL Definition interface Text : CharacterData { Text splitText(in unsigned long offset) raises(DOMException); }; Methods splitText Breaks this node into two 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. A new node of the same type, which is inserted as the next sibling of this node, contains all the content at and after the offset point. When the offset is equal to the length of this node, the new node has no data. Parameters offset of type unsigned long The 16-bit unit offset at which to split, starting from 0. Return Value Text The new node, of the same type as this 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 Level 1 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" and the version is "1.0". 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 cannot be nested. Their 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 CDATASection nodes are not merged by use of the normalize method on the Element interface. Note: Because no markup is recognized within a CDATASection, character numeric references cannot be used as an escape mechanism when serializing. Therefore, action needs to be taken when serializing a CDATASection with a character encoding where some of the contained characters cannot be represented. Failure to do so would not produce well-formed XML. One potential solution in the serialization process is to end the CDATA section before the character, output the character using a character reference or entity reference, and open a new CDATA section for any further characters in the text node. Note, however, that some code conversion libraries at the time of writing do not return an error or exception when a character is missing from the encoding, making the task of ensuring that data is not corrupted on serialization more difficult. 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 Level 1 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 1 doesn't support editing DocumentType nodes. IDL Definition interface DocumentType : Node { readonly attribute DOMString name; readonly attribute NamedNodeMap entities; readonly attribute NamedNodeMap notations; }; Attributes entities of type NamedNodeMap, readonly A NamedNodeMap containing the general entities, both external and internal, declared in the DTD. Parameter entities are not contained. Duplicates are discarded. For example in: ]> the interface provides access to foo and the first declaration of bar but not the second declaration of bar or baz. Every node in this map also implements the Entity interface. The DOM Level 1 does not support editing entities, therefore entities cannot be altered in any way. name of type DOMString, readonly The name of DTD; i.e., the name immediately following the DOCTYPE keyword. 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 1 does not support editing notations, therefore notations cannot be altered in any way. 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 [XML]), or is used for formal declaration of processing instruction targets (see section 2.6 of the XML 1.0 specification [XML]). 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 1 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. Entity nodes and all their descendants 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 notationName of type DOMString, readonly For unparsed entities, the name of the notation for the entity. For parsed entities, this is null. 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. 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. If such an Entity exists, then the child list of the EntityReference node is the same as that of the Entity node. As for Entity nodes, EntityReference nodes and all their descendants 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 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. 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. 29 September, 2000 2.

Introduction This section extends the Level 1 Core API to describe objects and methods specific to HTML documents [HTML4.0]. 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 the HTML 4.0 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 1 does not include mechanisms to access and modify style specified through CSS 1. Furthermore, it does not define an event model for HTML documents. This functionality is planned to be specified in a future Level of this specification. 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" and the version is "1.0". The interfaces in this specification are designed for HTML 4.0 documents, and not for XHTML documents. Use of the HTML DOM with XHTML documents may result in incorrect processing; see Appendix C11 in the [XHTML10] for more information. 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 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 index of type unsigned long 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 name of type DOMString 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. Besides 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 URL of type DOMString, readonly The complete URI of the 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. applets of type HTMLCollection, readonly A collection of all the OBJECT elements that include applets and APPLET (deprecated) elements in a document. body of type HTMLElement The element that contains the content for the document. In documents with BODY contents, returns the BODY element. In frameset documents, this returns the outermost FRAMESET element. 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. 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. forms of type HTMLCollection, readonly A collection of all the forms of a document. 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. 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. 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). title of type DOMString The title of a document as specified by the TITLE element in the head of the document. Methods close Closes a document stream opened by open() and forces rendering. No Parameters 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 elementId of type DOMString 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 elementName of type DOMString The name attribute value for an element. Return Value NodeList The matching elements. No Exceptions 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 write Write a string of text to a document stream opened by open(). The text is parsed into the document's structure model. Parameters text of type DOMString 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 text of type DOMString The string to be parsed into some structure in the document structure model. No Return Value No Exceptions 2.5. HTML Elements 2.5.1. Property Attributes HTML attributes are exposed as properties on the element object. The DOM naming conventions always determine the name of the exposed property, 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., (disabled)) 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 namespace 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 reserved for future usage. IDL Definition interface HTMLElement : Element { attribute DOMString id; attribute DOMString title; attribute DOMString lang; attribute DOMString dir; attribute DOMString className; }; Attributes className of type DOMString The class attribute of the element.

See the width attribute definition in HTML 4.0. 29 September, 2000 Appendix A: Changes Editors Philippe Le Hégaret, W3C This appendix contains the changes from the 1 October 1998 specification. A.1: Changes in the "What is the Document Object Model?" Introduction The link to the CORBA 2.2 specification was broken. Also, the first item of the list about "DOM Interfaces and DOM Implementations" had text about "read-only functions" which was changed to "read-only attributes". What the Document Object Model is The following sentence was missing: 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. The following statement has been modified: 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, with precisely the same objects and relationships. It now reads: 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]. with the following note: Note: There may be some variations depending on the parser being used to build the DOM. For instance, the DOM may not contain whitespaces in element content if the parser discards them. The compliance paragraph has been moved into a specific section (see Compliance). What the Document Object Model is not The following statement has been modified: The Document Object Model does not define "the true inner semantics" of XML or HTML. The semantics of those languages are defined by W3C Recommendations for these languages. The DOM is a programming model designed to respect these semantics. The DOM does not have any ramifications for the way you write XML and HTML documents; any document that can be written in these languages can be represented in the DOM. It now reads: 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. A.2: Changes in the Document Object Model Core Section 1.1.5. The DOMString type The DOMString type was defined as "a sequence of 16-bit quantities". Instead, it is now defined as "sequence of 16-bit units". Then, the description contained the following sentences: Please note that for both HTML and XML, the document character set (and therefore the notation of numeric character references) is based on UCS-4. A single numeric character reference in a source document may therefore in some cases correspond to two array positions in a DOMString (a high surrogate and a low surrogate). This now reads: 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). Section 1.1.6. String comparisons in the DOM The title of this section, which was Case sensitivity in the DOM, was changed to be more accurate. The first paragraph ended with the following: For the purposes of the DOM, string matching takes place on a character code by character code basis, on the 16 bit value of a DOMString. As such, the DOM assumes that any normalizations will take place in the processor, before the DOM structures are built. This sentence now reads: For the purposes of the DOM, string matching is performed purely by binary comparison of the 16-bit units of the DOMString. In addition, the DOM assumes that any normalizations take place in the processor, before the DOM structures are built. With the following note: Note: Besides case folding, there are additional normalizations that can be applied to text. The W3C I18N Working Group is in the process of defining exactly which normalizations are necessary, and where they should be applied. The W3C I18N Working Group expects to require early normalization, which means that data read into the DOM is assumed to already be normalized. The DOM and applications built on top of it in this case only have to assure that text remains normalized when being changed. For further details, please see [Charmod]. Section 1.2 Interface Attr The fact that setting the value attribute raises a NO_MODIFICATION_ALLOWED_ERR DOMException when the node is readonly was added. A sentence has been added at the end of the first paragraph of the description of the value attribute: See also the method getAttribute on the Element interface. also at the end of the second paragraph: I.e. any characters that an XML processor would recognize as markup are instead treated as literal text. See also the method setAttribute on the Element interface. And on the specified attribute: If the attribute is not associated to any element (i.e. because it was just created or was obtained from some removal or cloning operation) specified is true. Section 1.2 Interface CharacterData The following paragraph has been added: As explained in the DOMString interface, text strings in the DOM are represented in UTF-16, i.e. as a sequence of 16-bit units. In the following, the term 16-bit units is used whenever necessary to indicate that indexing on CharacterData is done in 16-bit units. The description of the length attribute read: The number of characters that are available through data and the substringData method below. It now reads: The number of 16-bit units that are available through data and the substringData method below. The description of the count parameter of the substringData method read: The number of characters to extract. It now reads: The number of 16-bit units to extract. Then the description of the return value read: The specified substring. If the sum of offset and count exceeds the length, then all characters to the end of the data are returned. It now reads: 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. The exception INDEX_SIZE_ERR was said to be: Raised if the specified offset is negative or greater than the number of characters in data, or if the specified count is negative. Instead this now reads: 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. The description of the insertData method read: Insert a string at the specified character offset. Instead it now reads: Insert a string at the specified 16-bit unit offset. Then the description of the offset parameter read: The character offset at which to insert. when it now reads: The 16-bit unit offset at which to insert. The exception INDEX_SIZE_ERR was said to be: Raised if the specified offset is negative or greater than the number of characters in data, or if the specified count is negative. Instead this now reads: 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. The description of the deleteData method read: Remove a range of characters from the node. Instead it now reads: Remove a range of 16-bit units from the node. Then the description of the count parameter read: The number of characters to delete. If the sum of offset and count exceeds length then all characters from offset to the end of the data are deleted. when it now reads: 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. The description of the replaceData method read: Replace the characters starting at the specified character offset with the specified string. instead it now reads: Replace the characters starting at the specified 16-bit unit offset with the specified string. Then the description of the count parameter read: The number of characters to replace. If the sum of offset and count exceeds length, then all characters to the end of the data are replaced when it now reads: 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 The exception INDEX_SIZE_ERR was said to be: Raised if the specified offset is negative or greater than the number of characters in data, or if the specified count is negative. Instead this now reads: 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. Section 1.2 Interface DOMImplementation The definition of the feature parameter read: The package name of the feature to test. In Level 1, the legal values are "HTML" and "XML" (case-insensitive). This now reads: The name of the feature to test (case-insensitive). The values used by DOM features are defined throughout this specification and listed i n the Compliance section. The name must be an XML name. To avoid possible conflicts, as a convention, names referring to features defined outside the DOM specification should be made unique by reversing the name of the Internet domain name of the person (or the organization that the person belongs to) who defines the feature, component by component, and using this as a prefix. For instance, the W3C SYMM Working Group defines the feature "org.w3c.dom.smil". The definition of the version parameter read: This is the version number of the package name to test. In Level 1, this is the string "1.0". This now reads: This is the version number of the feature to test. In Level 1, this is the string "1.0". Section 1.2 Interface Document The description of the createElement method was missing the following piece: In addition, if there are known attributes with default values, Attr nodes representing them are automatically created and attached to the element. The description of the createEntityReference method was missing the following piece: In addition, if the referenced entity is known, the child list of the EntityReference node is made the same as that of the corresponding Entity node. The description of the doctype attribute was missing the following piece: The DOM Level 1 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, which are inherited from the Node interface. The description of the createAttribute method was said to be: Creates an Attr of the given name. Note that the Attr instance can then be set on an Element using the setAttribute method. it is now: Creates an Attr of the given name. Note that the Attr instance can then be set on an Element using the setAttributeNode method. The description of the return value was missing: The value of the attribute is the emtpy string. The exception INVALID_CHARACTER_ERR for createElement, createAttribute, createEntityReference and createProcessingInstruction methods was said to be: Raised if the specified name contains an invalid character. Instead this now reads: Raised if the specified name contains an illegal character. Section 1.2 Interface DocumentType The description of the entities attribute has been modified: A NamedNodeMap containing the general entities, both external and internal, declared in the DTD. Duplicates are discarded. It now reads: A NamedNodeMap containing the general entities, both external and internal, declared in the DTD. Parameter entities are not contained. Duplicates are discarded. The example has been modified as follows: ]> the interface provides access to foo and bar but not baz. [ ...] It is now: ]> the interface provides access to foo and the first declaration of bar but not the second declaration of bar or baz. [...] Section 1.2 Interface Element The following example has been removed: 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. The following sentence has been added: The Element interface represents an element in an HTML or XML document. The description read: the generic Node interface method getAttributes may be used to retrieve the set of all attributes for an element. However, there is no getAttributes method per se, although it may exist in some language binding such as the java one. So this section now reads: the generic Node interface attribute attributes may be used to retrieve the set of all attributes for an element. The removeAttribute method description read: If the removed attribute has a default value it is immediately replaced. This now reads: If the removed attribute is known to have a default value, an attribute immediately appears containing the default value. The removeAttributeNode method description read: Removes the specified attribute. This now reads: Removes the specified attribute. If the removed Attr has a default value it is immediately replaced. The description of the oldAttr has been chagned according to the previous change: The Attr node to remove from the attribute list. If the removed Attr has a default value it is immediately replaced. This now reads: The Attr node to remove from the attribute list. In addition, the following note was added to the description of the normalize method: Note: In cases where the document contains CDATASections, the normalize operation alone may not be sufficient, since XPointers do not differentiate between Text nodes and CDATASection nodes. And the following change was made to the description of the same method: 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 now reads: Puts all Text nodes in the full depth of the sub-tree underneath this Element, including attribute nodes, 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. The exception INVALID_CHARACTER_ERR for the setAttribute method was said to be: Raised if the specified name contains an invalid character. Instead this now reads: Raised if the specified name contains an illegal character. The description for setAttributeNode was said to be: Adds a new attribute. Instead this now reads: Adds a new attribute node. The description for setAttributeNode return value was said to be: If the newAttr attribute replaces an existing attribute with the same name, the previously existing Attr node is returned, otherwise null is returned. Instead this now reads: If the newAttr attribute replaces an existing attribute, the replaced Attr node is returned, otherwise null is returned. Section 1.2 Interface DOMException The following note has been added for the ExceptionCode group: Note: Other numeric codes are reserved for W3C for possible future use. The description of the INVALID_CHARACTER_ERR read: If an invalid character is specified, such as in a name. Instead it now reads: If an invalid or illegal character is specified, such as in a name. See production 2 in the XML specification for the definition of a legal character, and production 5 for the definition of a legal name character. Section 1.2 Interface NamedNodeMap The description of the setNamedItem was missing (moved from the description of the arg parameter): If a node with that name is already present in this map, it is replaced by the new one. The description of the return value of the removeNamedItem method read: The node removed from the map or null if no node with such a name exists. But this error case is already handled by having the method to throw a NOT_FOUND_ERR DOMException. So this section now simply reads: The node removed from the map if a node with such a name exists. The description of the removeNamedItem method now includes the following note that was missing: When this map contains the attributes attached to an element, if the removed attribute is known to have a default value, an attribute immediately appears containing the default value. In addition, it was added that the removeNamedItem method raises a NO_MODIFICATION_ALLOWED_ERR DOMException when the NamedNodeMap is readonly. Section 1.2 Interface Node It was added to the description of the nodeValue attribute that setting it, when it is defined to be null, has no effect. It was also added to the description of the parentNode attribute that Entity and Notation nodes do not have a parent. It was also added to the description of the NodeType group: Numeric codes up to 200 are reserved to W3C for possible future use. The following description has been removed: 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. The description of the NO_MODIFICATION_ALLOWED_ERR exception of the insertBefore method read: Raised if this node is readonly. It now reads: Raised if this node is readonly or if the parent of the node being inserted is readonly. The description of the replaceChild method was missing: If newChild is a DocumentFragment object, oldChild is replaced by all of the DocumentFragment children, which are inserted in the same order. If the newChild is already in the tree, it is first removed. The description of the NO_MODIFICATION_ALLOWED_ERR exception of the replaceChild method read: Raised if this node is readonly. It now reads: Raised if this node or the parent of the new node is readonly. The description of the cloneNode method was missing: Note that cloning an immutable subtree results in a mutable copy, but the children of an EntityReference clone are readonly. In addition, clones of unspecified Attr nodes are specified. And, cloning Document, DocumentType, Entity, and Notation nodes is implementation dependent. and also missing the following exceptions: NOT_SUPPORTED_ERR: Raised if this node is a of type DOCUMENT_NODE, DOCUMENT_TYPE_NODE, ENTITY_NODE, or NOTATION_NODE and the implementation does not support cloning this type of node. Section 1.2 Interface NodeList The description was missing: NodeList objects in the DOM are live. Section 1.2 Interface Comment The first paragraph read: This represents the content of a comment, i.e., all the characters between the starting ''. It now reads "This interface inherits from CharacterData and represents ...". Section 1.2 Interface Text The first paragraph read: The Text interface represents the textual content (termed character data in XML) of an Element or Attr. It now reads "The Text interface inherits from CharacterData and represents ...". The first paragraph read: If there is markup, it is parsed into a list of elements and Text nodes that form the list of children of the element. It has been clarified, now reads "into the information items (elements, children comments, etc.) and ...". The last sentence of the second paragraph of the interface description read: 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. However, since in cases where the document contains CDATASections, the normalize operation alone may not be sufficient, since XPointers do not differentiate between Text nodes and CDATASection nodes, the last part of the sentence (after the semi-colon) was dropped. The following sentence was added, for clarification purpose, to the description of the splitText method: When the offset is equal to the length of this node, the new Text node has no data. The description of the slitText method has been clarified: Breaks this Text node into two Text at the specified offset, ... It now reads "Breaks this node into two nodes ...". The description offset parameter of the splitText method read: The offset at which to split, starting from 0. It now reads: The 16-bit unit offset at which to split, starting from 0. The description return value read: The new Text node. It now reads: The new node, of the same type as this node. The exception INDEX_SIZE_ERR was said to be: Raised if the specified offset is negative or greater than the number of characters in data. Instead this now reads: Raised if the specified offset is negative or greater than the number of 16-bit units in data. Section 1.3 Extended Interfaces The following paragraph was missing: 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". Section 1.3 Interface CDATASection The following note was added to the description: Note: Because no markup is recognized within a CDATASection, character numeric references cannot be used as an escape mechanism when serializing. Therefore, action needs to be taken when serializing a CDATASection with a character encoding where some of the contained characters cannot be represented. Failure to do so would not produce well-formed XML. One potential solution in the serialization process is to end the CDATA section before the character, output the character using a character reference or entity reference, and open a new CDATA section for any further characters in the text node. Note, however, that some code conversion libraries at the time of writing do not return an error or exception when a character is missing from the encoding, making the task of ensuring that data is not corrupted on serialization more difficult. Section 1.3. Interface Notation The first paragraph read: they are therefore readonly. A link to the glossary has been added for readonly. Section 1.3 Interface Entity The last sentence of the last paragraph was said to be: All the descendants of an Entity node are readonly. Instead, it now reads: Entity nodes and all their descendants are readonly. Section 1.3 Interface EntityReference The following note was added to the description: As for Entity nodes, EntityReference nodes and all their descendants are readonly. A.3: Changes in the Document Object Model HTML Section 2.1 Introduction The last sentence of the third paragraph was: Interoperability between implementations is only guaranteed for elements and attributes that are specified in these DTDs. This seemed to imply interoperability is not guaranteed for the HTML 4.0 strict DTD, so it was changed to: Interoperability between implementations is only guaranteed for elements and attributes that are specified in the HTML 4.0 DTDs. Section 2.5.1 Property Attributes "border" was given as an example of an open-value value list in the table. It was changed to "disabled". Section 2.5.5 Interface HTMLBlockquoteElement This interface was an error and was removed. The Interface HTMLQuoteElement is used for both the Q and BLOCKQUOTE HTML elements. Section 2.5.5 Interface HTMLInputElement The description of the defaultValue attribute now reads: value "Text", "File" or "Password", this represents the HTML value attribute of the element. The value of this attribute does not change if the contents of the corresponding form control in an interactive user agent changes. Changing this attribute, however, resets the contents of the form control. See the value attribute definition in HTML 4.0. The description of the value attribute now reads: When the type attribute of the element has the value "Text", "File" or "Password", this represents the current contents of the corresponding form control in an interactive user agent. Changing this attribute changes the contents of the form control, but does not change the value of the HTML value attribute of the element. When the type attribute of the element has the value "Button", "Hidden", "Submit", "Reset", "Image", "Checkbox" or "Radio", this represents the HTML value attribute of the element. See the value attribute definition in HTML 4.0. The description of the defaultChecked attribute now reads: When the type attribute of the element has the value "Checkbox" or "Radio", this represents the HTML checked attribute of the element. The value of this attribute does not change if the state of the corresponding form control in an interactive user agent changes. Changes to this attribute, however, resets the state of the form control. See the checked attribute definition in HTML 4.0. The description of the checked attribute now reads: When the type attribute of the element has the value "Checkbox" or "Radio", this represents the current state of the corresponding form control in am interactive user agent. Changes to this attribute changes the state of the form control, but does not change the value of the HTML value attribute of the element. Section 2.5.5 Interface HTMLOptionElement The index attribute was changed to readonly and the selected attribute to readwrite. It was also added that the index attribute starts from 0. The description of the defaultSelected attribute was unclear, it now reads: Represents the value of the HTML selected attribute. The value of this attribute does not change if the state of the corresponding form control in an interactive user agent changes. Changing defaultSelected, however, resets the state of the form control. See the selected attribute definition in HTML 4.0. In addition, its description was unclear, it now reads: Represents the current state of the corresponding form control in an interactive user agent. Changing this attribute changes the state of the form control, but does not change the value of the HTML selected attribute of the element. Section 2.5.5 Interface HTMLSelectElement It was added that the value of the type attribute is the string "select-multiple" when the multiple attribute is true and the string "select-one" when false. It was also added that the index attribute starts from 0. The description of the before parameter of the add method read: The element to insert before, or null for the head of the list. It was changed to: The element to insert before, or null for the tail of the list. Finally, it was added that an NOT_FOUND_ERR DOMException is raised when the before given to the add method is not a descendant of the SELECT element. Section 2.5.5 Interface HTMLTableCellElement The cellIndex attribute was changed to readonly and it was added that it starts from 0. Section 2.5.5 Interface HTMLTableElement The description of the index parameter of the insertRow and deleteRow methods was augmented with the following: This index starts from 0 and is relative to all the rows contained inside the table, regardless of section parentage. In addition, the following was added to the description of the insertRow method: The new row is inserted immediately before and in the same section as the current indexth row in the table. If there is no such row, the row is inserted following the one before in the table. Finally, when the table is empty the row is inserted into a TBODY which is created and inserted into the table. Finally, it was added that an INDEX_SIZE_ERR DOMException is raised when the index given to the insertRow method is greater than the number of rows, and when the index given to the deleteRow method is greater than or equal to the number of rows. In both case, the exception is also raised if the index is negative. Section 2.5.5 Interface HTMLTableRowElement The rowIndex, selectionRowIndex, and cells attributes were changed to readonly. And it was added that these indexes start from 0. It was added that the index parameter of the insertCell and deleteCell methods starts from 0. The following sentence was added to the description of the insertCell: If index is equal to the number of cells, the new cell is appended. In addition, it was added that an INDEX_SIZE_ERR DOMException is raised when the index given to the insertCell method is greater than the number of cells and when the index given to the deleteCell method is greater than or equal to the number of cells. In both case, the exception is also raised if the index is negative. Section 2.5.5 Interface HTMLTableSectionElement The description of the index parameter of the insertRow and deleteRow methods was augmented with the following: This index starts from 0 and is relative only to the rows contained inside this section, not all the rows in the table. In addition, it was added that an INDEX_SIZE_ERR DOMException is raised when the index given to the insertRow method is greater than the number of rows, and when the index given to the deleteRow method is greater than or equal to the number of rows. In both case, the exception is also raised if the index is negative. Section 2.5.5 Interface HTMLTextArea The value of the type attribute is now defined to be the string "textarea". The description of the defaultValue attribute was unclear, it now reads: Represents the contents of the element. The value of this attribute does not change if the contents of the corresponding form control in an interactive user agent changes. Changing this attribute, however, resets the contents of the form control. The description of the value attribute was unclear, it now reads: Represents the current contents of the corresponding form control in an interactive user agent. Changing this attribute changes the contents of the form control, but does not change the contents of the element. A.4: Changes in the Appendices Appendix D (formerly C): IDL Definition The list of exception codes appeared twice and several pieces of information, such as the names and prefixes of the modules were missing. We also added the following paragraph: "Unfortunately the OMG IDL for the Document Object Model HTML is not compliant because of problems in the validator that was used to validate Level 1. The readOnly attribute on the HTMLInputElement and HTMLTextAreaElement interfaces, as well as the object attribute on the HTMLAppletElement interface, are not compliant with OMG IDL 2.2. The valueType attribute on the HTMLParamElement interface is not compliant with OMG IDL 2.3, which hadn't been released when DOM Level 1 was published." Appendix E (formerly D): Java Language Binding The java source files did not contain the copyright notice appropriate for people to use them in their products. A few errors in the javadoc part of them were also fixed. References The references were sorted by alphabetical order, severals references were added and updated. 29 September, 2000 Appendix E: Acknowledgements The authors of this specification, members of the DOM Working Group, deserve much credit for their hard work: Lauren Wood (SoftQuad, Inc., chair), Arnaud Le Hors (W3C, W3C staff contact), Andrew Watson (Object Management Group), Bill Smith (Sun), Chris Lovett (Microsoft), Chris Wilson (Microsoft), David Brownell (Sun), David Singer (IBM), Don Park (invited), Eric Vasilik (Microsoft), Gavin Nicol (INSO), Ian Jacobs (W3C), James Clark (invited), Jared Sorensen (Novell), Jonathan Robie (Texcel Research and Software AG), Mike Champion (ArborText and Software AG), Paul Grosso (ArborText), Peter Sharpe (SoftQuad, Inc.), Phil Karlton (Netscape), Ray Whitmer (iMall), Rich Rollman (Microsoft), Rick Gessner (Netscape), Robert Sutor (IBM), Scott Isaacs (Microsoft), Sharon Adler (INSO), Steve Byrne (JavaSoft), Tim Bray (invited), Tom Pixley (Netscape), Vidur Apparao (Netscape).

Thanks to Jan Kärrman, author of html2ps for helping so much in creating the Postscript version of the specification. 29 September, 2000 Glossary Editors Robert S. Sutor, IBM Research 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. This indicates that indexing on a DOMString occurs in units of 16 bits. This must not be misunderstood to mean that a DOMString can store arbitrary 16-bit units. A DOMString is a character string encoded in UTF-16; this means that the restrictions of UTF-16 as well as the other relevant restrictions on character strings must be maintained. A single character, for example in the form of a numeric character reference, may correspond to one or two 16-bit units. For more information, see [Unicode] and [ISO/IEC 10646]. 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 context specifies 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 cursor is 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 the 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, their child node lists are equivalent are equivalent as NodeList objects, and their attributes are 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 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. information item An information item is an abstract representation of some component of an XML document. See the [Infoset] for details. 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. [HTML3.2] [HTML4.0] IDL An Interface Definition Language (IDL) is used to define the interfaces for accessing and operating 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. 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. 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. readonly node A readonly node is a node that is immutable. This means its list of children, its content, and its attributes, when it is an element, cannot be changed in any way. However, a readonly node can possibly be moved, when it is not itself contained in a readonly node. 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. 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 3.0 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. 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 name See XML name in the XML specification [XML]. 29 September, 2000 Appendix B: IDL Definitions This appendix contains the complete OMG IDL for the Level 1 Document Object Model definitions. The definitions are divided into Core, HTML. The IDL files are also available as: http://www.w3.org/TR/2000/WD-DOM-Level-1-20000929/idl.zip Unfortunately the OMG IDL for the Document Object Model HTML is not compliant because of problems in the validator that was used to validate Level 1. The readOnly attribute on the HTMLInputElement and HTMLTextAreaElement interfaces, as well as the object attribute on the HTMLAppletElement interface, are not compliant with OMG IDL 2.2. B.1: Document Object Model Level 1 Core This section contains the OMG IDL definitions for the interfaces in the Core Document Object Model specification, including the extended (XML) interfaces. dom.idl: // File: dom.idl #ifndef _DOM_IDL_ #define _DOM_IDL_ #pragma prefix "w3c.org" module dom { typedef sequence DOMString;

good example of the power of using XML: all of the HTML documents, Java bindings, OMG IDL bindings, and ECMA Script bindings are generated from a single set of XML source files. This section outlines how this specification is written in XML, and how the various derived works are created. A. The Document Type Definition This specification was written entirely in XML, using a DTD based heavily on the DTD used by the XML Working Group for the XML specification. The major difference between the DTD used by the XML Working Group, and the DTD used for this specification is the addition of a DTD module for interface specifications. The DTD module for interfaces specifications is a very loose translation of the Extended Backus-Naur Form (EBNF) specification of the OMG IDL syntax into XML DTD syntax. In addition to the translation, the ability to describe the interfaces was added, thereby creating a limited form of literate programming for interface definitions. While the DTD module is sufficient for the purposes of the DOM WG, it is very loosely typed, meaning that there are very few constraints placed on the type specifications (the type information is effectively treated as an opaque string). In a DTD for object to object communication, some stricter enforcement of data types would probably be beneficial. B. The production process The DOM specification is written using XML. All documents are valid XML. In order to produce the HTML versions of the specification, the object indexes, the Java source code, and the OMG IDL and ECMA Script definitions, the XML specification is converted. The tool currently used for conversion is COST by Joe English. COST takes the ESIS output of nsgmls, creates an internal representation, and then allows scripts, and event handlers to be run over the internal data structure. Event handlers allow document patterns and associated processing to be specified: when the pattern is matched during a pre-order traversal of a document subtree, the associated action is executed. This is the heart of the conversion process. Scripts are used to tie the various components together. For example, each of the major derived data sources (Java code etc.) is created by the execution of a script, which in turn executes one or more event handlers. The scripts and event handlers are specified using TCL. The current version of COST has been somewhat modified from the publicly available version. In particular, it now runs correctly under 32-bit Windows, uses TCL 8.0, and correctly handles the case sensitivity of XML (though it probably could not correctly handle native language markup). We could also have used Jade, by James Clark. Like COST, Jade allows patterns and actions to be specified, but Jade is based on DSSSL, an international standard, whereas COST is not. Jade is more powerful than COST in many ways, but prior experience of the editor with Cost made it easier to use this rather than Jade. A future version or Level of the DOM specification may be produced using Jade or an XSL processor. The complete XML source files are available at: http://www.w3.org/TR/2000/WD-DOM-Level-1-20000929/xml-source.zip Note: The DOM Level 1 Specification Second Edition has been produced using a DOM Level 2 implementation and an XPath implementation in Java. C. Object Definitions As stated earlier, all object definitions are specified in XML. The Java bindings, OMG IDL bindings, and ECMA Script bindings are all generated automatically from the XML source code. This is possible because the information specified in XML is a superset of what these other syntax need. This is a general observation, and the same kind of technique can be applied to many other areas: given rich structure, rich processing and conversion are possible. For Java and OMG IDL, it is basically just a matter of renaming syntactic keywords; for ECMA Script, the process is somewhat more involved. A typical object definition in XML looks something like this:

Description goes here...

Description goes here...

Description goes here...

Description goes here...

 As can easily be seen, this is quite verbose, but not unlike OMG IDL. In fact, when the specification was originally converted to use XML, the OMG IDL definitions were automatically converted into the corresponding XML source using common Unix text manipulation tools.
