# XML DOM - The Attr Object

The Attr object represents an attribute of an Element object.

## 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.

IE: Internet Explorer, F: Firefox, O: Opera, W3C: World Wide Web Consortium (Internet Standard)
