String getAttributeNS(String namespaceURI, String localName);
namespaceURI
The URI that uniquely identifies the namespace of this attribute, or null for no namespace.
localName
The identifier that specifies the name of the attribute within its namespace.
The string value of the named attribute. If the attribute is not explicitly specified in the document and does not have a default value specified by the document type, this method returns the empty string.
This method works just like the getAttribute( ) method, except that the attribute is specified by a combination of namespace URI and local name within that namespace. This method is useful only with XML documents that use namespaces.
