javascript Element getAttributeNode( )

Returns a reference to the attribute node (Attr object) associated with the name. This type of node is the same kind that populates the array returned by an element's attributes property, but the getAttributeNode( ) method gives you direct access to the Attr node object by name. More helpful in XML documents, where an attribute can convey important data associated with the element. See the Attr object for details about that node type.
