8.6.2.6 Element Objects


8.6.2.6 Element Objects

Element is a subclass of Node, so inherits all the attributes of that class.

tagName
The element type name. In a namespace-using document it may have colons in it. The value is a string.

getElementsByTagName( tagName)
Same as equivalent method in the Document class.

getElementsByTagNameNS( tagName)
Same as equivalent method in the Document class.

hasAttribute( name)
Returns true if the element has an attribute named by name.

hasAttributeNS( namespaceURI, localName)
Returns true if the element has an attribute named by namespaceURI and localName.

getAttribute( name)
Return the value of the attribute named by name as a string. If no such attribute exists, an empty string is returned, as if the attribute had no value.

getAttributeNode( attrname)
Return the Attr node for the attribute named by attrname.

getAttributeNS( namespaceURI, localName)
Return the value of the attribute named by namespaceURI and localName as a string. If no such attribute exists, an empty string is returned, as if the attribute had no value.

getAttributeNodeNS( namespaceURI, localName)
Return an attribute value as a node, given a namespaceURI and localName.

removeAttribute( name)
Remove an attribute by name. No exception is raised if there is no matching attribute.

removeAttributeNode( oldAttr)
Remove and return oldAttr from the attribute list, if present. If oldAttr is not present, NotFoundErr is raised.

removeAttributeNS( namespaceURI, localName)
Remove an attribute by name. Note that it uses a localName, not a qname. No exception is raised if there is no matching attribute.

setAttribute( name, value)
Set an attribute value from a string.

setAttributeNode( newAttr)
Add a new attribute node to the element, replacing an existing attribute if necessary if the name attribute matches. If a replacement occurs, the old attribute node will be returned. If newAttr is already in use, InuseAttributeErr will be raised.

setAttributeNodeNS( newAttr)
Add a new attribute node to the element, replacing an existing attribute if necessary if the namespaceURI and localName attributes match. If a replacement occurs, the old attribute node will be returned. If newAttr is already in use, InuseAttributeErr will be raised.

setAttributeNS( namespaceURI, qname, value)
Set an attribute value from a string, given a namespaceURI and a qname. Note that a qname is the whole attribute name. This is different than above.
