Detailed Description

By far the vast majority of objects (apart from text) that authors encounter when traversing a document are DOMElement nodes.

Assume the following XML document:<elementExample id="demo"> <subelement1/> <subelement2><subsubelement/></subelement2> </elementExample>

When represented using DOM, the top node is an DOMElement node for "elementExample", which contains two child DOMElement nodes, one for "subelement1" and one for "subelement2". "subelement1" contains no child nodes.

Elements may have attributes associated with them; since the DOMElement interface inherits from DOMNode, the generic DOMNode interface method getAttributes may be used to retrieve the set of all attributes for an element. There are methods on the DOMElement interface to retrieve either an DOMAttr object by name or an attribute value by name. In XML, where an attribute value may contain entity references, an DOMAttr 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.

Parameters

oldAttr The DOMAttr node to remove from the attribute list.

◆ setAttribute()

virtual void DOMElement::setAttribute	(	const XMLCh *	name,
		const XMLCh *	value )

pure virtual

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 DOMAttr node plus any DOMText and DOMEntityReference nodes, build the appropriate subtree, and use setAttributeNode to assign it as the value of an attribute.

Parameters

name	The name of the attribute to create or alter.
value	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.

Since: DOM Level 1

◆ setAttributeNode()

virtual DOMAttr * DOMElement::setAttributeNode ( DOMAttr * newAttr )

pure virtual

Adds a new attribute.

If an attribute with that name (nodeName) is already present in the element, it is replaced by the new one.

Parameters

newAttr The DOMAttr node to add to the attribute list.

Returns: If the newAttr attribute replaces an existing attribute, the replaced DOMAttr 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 DOMElement object. The DOM user must explicitly clone DOMAttr nodes to re-use them in other elements.

Since: DOM Level 1

◆ setAttributeNodeNS()

virtual DOMAttr * DOMElement::setAttributeNodeNS ( DOMAttr * newAttr )

pure virtual

Adds a new attribute.

If an attribute with that local name and namespace URI is already present in the element, it is replaced by the new one.

Parameters

newAttr The DOMAttr node to add to the attribute list.

Returns: If the newAttr attribute replaces an existing attribute with the same local name and namespace URI, the replaced DOMAttr 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 DOMElement object. The DOM user must explicitly clone DOMAttr nodes to re-use them in other elements.

Since: DOM Level 2

◆ setAttributeNS()

virtual void DOMElement::setAttributeNS	(	const XMLCh *	namespaceURI,
		const XMLCh *	qualifiedName,
		const XMLCh *	value )

pure virtual

Adds a new attribute.

If an attribute with the same local name and namespace URI is already present on the element, its prefix is changed to be the prefix part of the qualifiedName, and its value is changed to be 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 DOMAttr node plus any DOMText and DOMEntityReference nodes, build the appropriate subtree, and use setAttributeNodeNS or setAttributeNode to assign it as the value of an attribute.

Parameters

namespaceURI	The namespace URI of the attribute to create or alter.
qualifiedName	The qualified name of the attribute to create or alter.
value	The value to set in string form.

Exceptions

DOMException INVALID_CHARACTER_ERR: Raised if the specified qualified name contains an illegal character.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NAMESPACE_ERR: Raised if the qualifiedName is malformed, if the qualifiedName has a prefix and the namespaceURI is null or an empty string, if the qualifiedName has a prefix that is "xml" and the namespaceURI is different from "http://www.w3.org/XML/1998/namespace", if the qualifiedName has a prefix that is "xmlns" and the namespaceURI is different from "http://www.w3.org/2000/xmlns/", or if the qualifiedName is "xmlns" and the namespaceURI is different from "http://www.w3.org/2000/xmlns/".

Since: DOM Level 2

◆ setIdAttribute()

virtual void DOMElement::setIdAttribute	(	const XMLCh *	name,
		bool	isId )

pure virtual

If the parameter isId is true, this method declares the specified attribute to be a user-determined ID attribute.

This affects the value of DOMAttr::isId and the behavior of DOMDocument::getElementById, but does not change any schema that may be in use, in particular this does not affect the DOMAttr::getSchemaTypeInfo of the specified DOMAttr node. Use the value false for the parameter isId to undeclare an attribute for being a user-determined ID attribute. To specify an DOMAttr by local name and namespace URI, use the setIdAttributeNS method.

Parameters

name	The name of the `DOMAttr`.
isId	Whether the attribute is of type ID.

Exceptions

DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NOT_FOUND_ERR: Raised if the specified node is not an DOMAttr of this element.

Since: DOM Level 3

◆ setIdAttributeNode()

virtual void DOMElement::setIdAttributeNode	(	const DOMAttr *	idAttr,
		bool	isId )

pure virtual

If the parameter isId is true, this method declares the specified attribute to be a user-determined ID attribute.

This affects the value of DOMAttr::isId and the behavior of DOMDocument::getElementById, but does not change any schema that may be in use, in particular this does not affect the DOMAttr::getSchemaTypeInfo of the specified DOMAttr node. Use the value false for the parameter isId to undeclare an attribute for being a user-determined ID attribute.

Parameters

idAttr	The `DOMAttr` node.
isId	Whether the attribute is of type ID.

Exceptions

DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NOT_FOUND_ERR: Raised if the specified node is not an DOMAttr of this element.

◆ setIdAttributeNS()

virtual void DOMElement::setIdAttributeNS	(	const XMLCh *	namespaceURI,
		const XMLCh *	localName,
		bool	isId )

pure virtual

If the parameter isId is true, this method declares the specified attribute to be a user-determined ID attribute.

This affects the value of DOMAttr::isId and the behavior of DOMDocument::getElementById, but does not change any schema that may be in use, in particular this does not affect the DOMAttr::getSchemaTypeInfo of the specified DOMAttr node. Use the value false for the parameter isId to undeclare an attribute for being a user-determined ID attribute.

Parameters

namespaceURI	The namespace URI of the `DOMAttr`.
localName	The local name of the `DOMAttr`.
