NIST The "getNamespaceURI()" method for an Attribute returns the namespace URI of this node, or null if unspecified. Retrieve the first "emp:address" node which has an attribute of "emp:district" that is specified in the DTD. Invoke the "getNamespaceURI()" method on the attribute. The method should return "http://www.nist.gov". Mary Brady 2001-08-17
