Document Object Model for MathML

The following sections describe the interfaces that have been defined in the Document Object Model for MathML. Please refer to for more information.

Bindings for IDL, Java and ECMAScript are located in .

IDL Interfaces Miscellaneous Object Definitions

This interface extends the DOMImplementation interface by adding a method to create a MathMLDocument.

Creates a MathMLDocument with a minimal tree containing only a MathMLMathElement corresponding to a MathML math element. The MathMLMathElement is empty, having no child elements or non-default attributes; it is the root element of the document, and is the element accessed via the documentElement attribute of the MathMLDocument. Note that a MathMLDocument object should only be created for a stand-alone MathML document.

The MathMLDocument created.

This interface extends the Document interface to add access to document properties relating to navigation. The documentElement attribute for a MathMLDocument should be the MathMLMathElement representing the top-level math element which is the root of the document.

The URI of the page that linked to this document, if available. This is null if the user navigated directly to the page. If this is not a stand-alone MathML document (e.g. is embedded in an XHTML document), this may be retrieved from the parent Document if available.

The domain name of the server that served the document, or null if the server cannot be identified by a domain name, or if it is not available. If this is not a stand-alone MathML document (e.g. is embedded in an XHTML document), this may be retrieved from the parent Document if available.

The complete URI of this document. This is null if this is not a stand-alone MathML document.

This interface is provided as a specialization of the NodeList interface. The child Nodes of this NodeList must be MathMLElements or Text nodes.

Note that MathMLNodeLists are frequently used in the DOM as values of readonly attributes, encapsulating, for instance, various collections of child elements. When used in this way, these objects are always understood to be live, in the sense that changes to the document are immediately reflected in them.

Generic MathML Elements

All MathML element interfaces derive from this object, which derives from the basic DOM interface Element.

The class attribute of the element. See the discussion elsewhere in this document of the class attribute; see also the HTML definition of this attribute.

A string identifying the element's style attribute.

The element's identifier. See the discussion elsewhere in this document of the id attribute; see also the HTML definition.

The xref attribute of the element. See the discussion elsewhere in this document of the xref attribute.

The xlink:href attribute of the element. See the discussion elsewhere in this document of the xlink:href attribute; see also the definition of this attribute in the XLink specification.

The MathMLMathElement corresponding to the nearest math element ancestor of this element. Should be null if this element is a top-level math element.

This is an abstract interface containing functionality required by MathML elements that may contain arbitrarily many child elements. No elements are directly supported by this interface; all instances are instances of either MathMLPresentationContainer, MathMLContentContainer, or MathMLMathElement.

The number of child elements of this element which represent arguments of the element, as opposed to qualifiers or declare elements. Thus for a MathMLContentContainer it does not contain elements representing bound variables, conditions, separators, degrees, or upper or lower limits (bvar, condition, sep, degree, lowlimit, or uplimit).

This attribute accesses the child MathMLElements of this element which are arguments of it, as a MathMLNodeList. Note that this list does not contain any MathMLElements representing qualifier elements or declare elements.

Provides access to the declare elements which are children of this element, in a MathMLNodeList. All Nodes in this list must be MathMLDeclareElements.

This method returns the indexth child argument element of this element. This frequently differs from the value of Node::childNodes().item(index), as qualifier elements and declare elements are not counted.

The one-based index of the argument to be retrieved.

A MathMLElement representing the index-th argument of this element.

INDEX_SIZE_ERR: Raised if index is greater than the number of child elements.

This method sets newArgument as the index-th argument of this element. If there is currently an index-th argument, it is replaced by newArgument. This frequently differs from setting the node at Node::childNodes().item(index), as qualifier elements and declare elements are not counted.

A MathMLElement representing the element that is to be set as the index-th argument of this element.

The index of the argument that is to be set to newArgument. The first argument is numbered 1. If index is one more than the current number of arguments, a new argument is appended.

HIERARCHY_REQUEST_ERR: Raised if this element does not permit a child element of the type of newArgument, if this is a MathMLContentContainer and newArgument is a qualifier element, or if newElement is a MathMLDeclareElement.

INDEX_SIZE_ERR: Raised if index is greater than one more than the number of child elements.

This method inserts newArgument before the current index-th argument of this element. If index is 0, or if index is one more than the current number of arguments, newArgument is appended as the last argument. This frequently differs from setting the node at Node::childNodes().item(index), as qualifier elements and declare elements are not counted.

A MathMLElement representing the element that is to be inserted as a child argument of this element.

The one-based index of the position before which newArgument is to be inserted. The first argument is numbered 1.

The MathMLElement child of this element that represents the new argument in the DOM.

HIERARCHY_REQUEST_ERR: Raised if this element does not permit a child argument of the type of newArgument, or, for MathMLContentContainers, if newArgument represents a qualifier element.

This method deletes the index-th child element that is an argument of this element. Note that child elements which are qualifier elements or declare elements are not counted in determining the index-th argument.

The one-based index of the argument to be deleted.

None.

INDEX_SIZE_ERR: Raised if index is greater than the number of child elements.

This method deletes the index-th child element that is an argument of this element, and returns it to the caller. Note that child elements that are qualifier elements or declare elements are not counted in determining the index-th argument.

The one-based index of the declare element to be removed.

The MathMLDeclareElement being removed as a child Node of this element.

INDEX_SIZE_ERR: Raised if index is greater than the number of child declare elements.

This method deletes the MathMLDeclareElement representing the index-th declare child element of this element. Note that index is the position in the list of declare element children, as opposed to the position in the list of all child Nodes.

The one-based index of the declare element to be removed.

None.

INDEX_SIZE_ERR: Raised if index is greater than the number of child declare elements.

This interface represents the top-level MathML math element.

It may become useful for interfacing between the Document Object Model objects encoding an enclosing document and the MathML DOM elements that are its children. It could also be used for some purposes as a MathML DOM surrogate for a Document object. For instance, MathML-specific factory methods could be placed here, as could methods for creating MathML-specific Iterators or TreeWalkers. However, this functionality is as yet undefined.

Presentation Elements

This interface is provided to serve as a base interface for various MathML Presentation interfaces. It contains no new attributes or methods at this time; however, it is felt that the distinction between Presentation and Content MathML entities should be indicated in the MathMLElement hierarchy. In particular, future versions of the MathML DOM may add functionality on this interface; it may also serve as an aid to implementors.

Leaf Presentation Element Interfaces

This interface supports the mglyph element .

A string giving an alternate name for the character. Represents the mglyph's alt attribute.

A string representing the font family.

An unsigned integer giving the glyph's position within the font.

This interface extends the MathMLPresentationElement interface for the MathML space element mspace. Note that this is not derived from MathMLPresentationToken, despite the fact that mspace is classified as a token element, since it does not carry the attributes declared for MathMLPresentationToken.

A string of the form number h-unit; represents the width attribute for the mspace element, if specified.

A string of the form number v-unit; represents the height attribute for the mspace element, if specified.

Presentation Token Element Interfaces

Interfaces representing the MathML Presentation token elements that may have content are described here.

This interface extends the MathMLElement interface to include access for attributes specific to text presentation. It serves as the base class for all MathML presentation token elements. Access to the body of the element is via the nodeValue attribute inherited from Node. Elements that expose only the core presentation token attributes are directly supported by this object. These elements are: mi

identifier element

number element

mtext

text element

This interface extends the MathMLElement interface for the MathML style element mstyle. While the mstyle element may contain any attributes allowable on any MathML presentation element, only attributes specific to the mstyle element are included in the interface below. Other attributes should be accessed using the methods on the base Element class, particularly the Element::getAttribute and Element::setAttribute methods, or even the Node::attributes attribute to access all of them at once. Not only does this obviate a lengthy list below, but it seems likely that most implementations will find this a considerably more useful interface to a MathMLStyleElement.

Content Elements

This interface is provided to serve as a base interface for various MathML Content interfaces. It contains no new attributes or methods at this time; however, it is felt that the distinction between Presentation and Content MathML entities should be indicated in the MathMLElement hierarchy. In particular, future versions of the MathML DOM may add functionality on this interface; it may also serve as an aid to implementors.

Content Token Interfaces

This is the interface from which the interfaces representing the MathML Content token elements (ci, cn and csymbol) are derived. These elements may contain MathML Presentation elements, Text nodes, or a combination of both. Thus the getArgument and insertArgument methods have been provided to deal with this distinction between these elements and other MathML Content elements.

The arguments of this element, returned as a MathMLNodeList. Note that this is not necessarily the same as Node::childNodes, particularly in the case of the cn element. The reason is that the sep elements that are used to separate the arguments of a cn are not returned.

Node to be inserted as the argument. This will either be a MathMLElement or a Text node.

Position of the argument that is to be set to newArgument in the list of arguments. The first argument is numbered 1. Note that this is not necessarily the index of the Node in the list of child nodes, as nodes representing such elements as sep are not counted as arguments.

This interface represents the csymbol element. Although it currently has no attributes or methods distinct from those of MathMLContentToken, a separate interface is provided to emphasize the conceptual role of the csymbol element.

Content Container Interfaces

We have added interfaces for content elements that are containers, i.e. elements that may contain child elements corresponding to arguments, bound variables, conditions, or lower or upper limits.

This interface supports the MathML Content elements that may contain child Content elements. The elements directly supported by MathMLContentContainer include: reln (deprecated), lambda, lowlimit, uplimit, degree, domainofapplication, and momentabout. Interfaces derived from MathMLContentContainer support the elements apply, fn, interval, condition, declare, bvar, set, list, vector, matrix, and matrixrow.

The number of bvar child elements of this element.

This attribute represents the condition child element of this node. See .

HIERARCHY_REQUEST_ERR: Raised if this element does not permit a child condition element. In particular, raised if this element is not a apply, set, or list.

This attribute represents the degree child element of this node. This expresses, for instance, the degree of differentiation if this element is a bvar child of an apply element whose first child is a diff or partialdiff. If this is an apply element whose first child is a partialdiff, the opDegree attribute, if present, represents the total degree of differentiation. See .

HIERARCHY_REQUEST_ERR: Raised if this element does not permit a child degree element. In particular, raised if this element is not a bvar or apply.

This attribute represents the domainofapplication child element of this node, if present. This may express, for instance, the domain of integration if this element is an apply element whose first child is an integral operator (int). See .

This has the effect of adding a bound variable to the expression this element represents. Note that the new bound variable is inserted as the index-th bvar child node, not necessarily as the index-th child node. The point of the method is to allow insertion of bound variables without requiring the caller to calculate the exact order of child qualifier elements.

A MathMLBvarElement representing the bvar element being added.

The one-based index into the bound variable children of this element before which newBVar is to be inserted.

The MathMLBvarElement being added.

Note that the new bound variable is inserted as the index-th bvar child node, not necessarily as the index-th child node. The point of the method is to allow insertion of bound variables without requiring the caller to calculate the exact order of child qualifier elements. If there is already a bvar at the index-th position, it is replaced by newBVar.

The new MathMLBvarElement child of this element being set.

The one-based index into the bound variable children of this element at which newBVar is to be inserted.

The MathMLBvarElement being set.

This is true if the set is specified by giving the list of its elements explicitly.

The type attribute of the represented element. Predefined values are normal and multiset. See and .

The list element is the container element which represents a list of elements. Elements can be defined either by explicitly listing the elements, or by using the bvar and condition elements.

This is true if the list is specified by giving its elements explicitly.

The order attribute of the represented element. Predefined values are numeric and lexicographic. See and .

This interface represents the MathML bound variable element bvar. The interface currently provides no functionality beyond that of MathMLContentContainer, but is useful for defining the type of bound variable access functions.

INDEX_SIZE_ERR: Raised if index is greater one more than the number of pieces in this element.

A convenience method to retrieve the child of the indexth piece in this element which specifies the function value for that case.

Position of the piece whose value is being requested in the list of pieces. The first piece is numbered 1; the otherwise child (if present) is not counted, regardless of its position.

The MathMLContentElement representing the value to be taken by the function in the indexth case.

INDEX_SIZE_ERR: Raised if index is greater than the number of pieces in this element.

A convenience method to set the function value for the indexth piece in this element.

Position of the piece whose value is being set in the list of pieces. The first piece is numbered 1; the otherwise child (if present) is not counted, regardless of its position.

A MathMLContentElement representing the function value to be assigned in the indexth case.

The MathMLContentElement representing the value to be taken by the function in the indexth case.

INDEX_SIZE_ERR: Raised if index is greater than the number of pieces in this element.

A convenience method to retrieve the child of the piece at the position referenced by index which gives the condition for this case.

Position of the piece whose condition is being requested in the list of pieces. The first piece is numbered 1; the otherwise child (if present) is not counted, regardless of its position.

The MathMLContentElement representing the condition to be satisfied for the indexth case.

INDEX_SIZE_ERR: Raised if index is greater than the number of pieces in this element.

A convenience method to set the condition for the indexth piece in this element.

Position of the piece whose condition is being set in the list of pieces. The first piece is numbered 1; the otherwise child (if present) is not counted, regardless of its position.

A MathMLContentElement representing the condition to be associated to the indexth case.

The MathMLContentElement which is inserted as the condition child of the indexth piece.

INDEX_SIZE_ERR: Raised if index is greater than the number of pieces in this element.

The piece element represents one of a sequence of cases used in the piecewise definition of a function. It contains two child elements, each represented by a MathMLContentElement. The first child determines the subset of the domain affected, normally by giving a condition to be satisfied. The second gives the value of the function over the indicated subset of its domain.

Accesses the MathMLContentElement representing the condition to be satisfied in order for this branch of the piecewise definition to be used.

Accesses the MathMLContentElement representing the value to be taken by the piecewise function when the condition described by caseCondition is true.
