Detailed Description

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: <elementExample id="demo"> <subelement1/> <subelement2><subsubelement/></subelement2> </elementExample>

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

Elements may have attributes associated with them; since the Element interface inherits from Node , the generic Node interface method getAttributes 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.

Exceptions

DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

Definition at line 174 of file dom_element.cpp.

◆ removeAttributeNode()

Attr Element::removeAttributeNode ( const Attr & oldAttr )

Removes the specified attribute.

◆ removeAttributeNS()

void Element::removeAttributeNS	(	const DOMString &	namespaceURI,
		const DOMString &	localName
	)

Introduced in DOM Level 2.

Removes an attribute by local name and namespace URI. If the removed attribute has a default value it is immediately replaced. The replacing attribute has the same namespace URI and local name, as well as the original prefix.

HTML-only DOM implementations do not need to implement this method.

Parameters

namespaceURI	The namespace URI of the attribute to remove.
localName	The local name of the attribute to remove.

Exceptions

DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

Definition at line 271 of file dom_element.cpp.

◆ setAttribute()

void Element::setAttribute	(	const DOMString &	name,
		const DOMString &	value
	)

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	The name of the attribute to create or alter.
value	Value to set in string form.

Returns

Exceptions

DOMException INVALID_CHARACTER_ERR: Raised if the specified name contains an invalid character.

NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

Definition at line 162 of file dom_element.cpp.

◆ setAttributeNode()

Attr Element::setAttributeNode ( const Attr & newAttr )

Adds a new attribute.

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

Parameters

newAttr The Attr node to add to the attribute list.

Returns: If the newAttr attribute replaces an existing attribute with the same name, the previously existing Attr node is returned, otherwise null is returned.

Exceptions

DOMException WRONG_DOCUMENT_ERR: Raised if newAttr was created from a different document than the one that created the element.

NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

INUSE_ATTRIBUTE_ERR: Raised if newAttr is already an attribute of another Element object. The DOM user must explicitly clone Attr nodes to re-use them in other elements.

Definition at line 201 of file dom_element.cpp.

◆ setAttributeNodeNS()

Attr Element::setAttributeNodeNS ( const Attr & newAttr )

Introduced in DOM Level 2.

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

HTML-only DOM implementations do not need to implement this method.

Parameters

newAttr The Attr 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 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.

Definition at line 297 of file dom_element.cpp.

◆ setAttributeNS()

void Element::setAttributeNS	(	const DOMString &	namespaceURI,
		const DOMString &	qualifiedName,
		const DOMString &	value
	)

Introduced in DOM Level 2.

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 Attr node plus any Text and EntityReference nodes, build the appropriate subtree, and use setAttributeNodeNS or setAttributeNode to assign it as the value of an attribute.

HTML-only DOM implementations do not need to implement this method.

Parameters

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, if the qualifiedName has a prefix that is "xml" and the namespaceURI is different from "http://www.w3.org/XML/1998/namespace", or if the qualifiedName is "xmlns" and the namespaceURI is different from "http://www.w3.org/2000/xmlns/".

Definition at line 259 of file dom_element.cpp.

◆ setContentEditable()

void Element::setContentEditable ( bool enabled )

not part of the official DOM

This element can be made editable by setting its contentEditable property to true. The setting will be inherited to its children as well.

Setting or clearing contentEditable when design mode is active will take no effect. However, its status will still be propagated to all child elements.

Parameters

enabled true to make this element editable, false otherwise.

See also: DOM::Document::designMode

Since: 3.2

Definition at line 360 of file dom_element.cpp.

◆ style()

CSSStyleDeclaration Element::style ( )

Introduced in DOM Level 2 This method is from the CSSStyleDeclaration interface.

The style attribute

Definition at line 349 of file dom_element.cpp.

◆ tagName()

DOMString Element::tagName ( ) const

The name of the element.

For example, in: <elementExample id="demo"> ... </elementExample> , 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.
