          <description> The method getAttributeNodeNS retrieves an Attr node by local name and namespace URI. Create a new element node and add 2 new attribute nodes to it that have the same local name but different namespaceURIs and prefixes. Retrieve an attribute using namespace and localname and check its value, name and namespaceURI. </description>
