The Attr object
The Attr object represents an attribute of an Element object. The allowable values for attributes are usually defined in a DTD.
Because the Attr object is also a Node, it inherits the Node object's properties and methods. However, an attribute does not have a parent node and is not considered to be a child node of an element, and will return null for many of the Node properties.
