Name

Element.getAttributeNS( ): get the value of an attribute that uses namespaces — DOM Level 2 Core:

Synopsis

String getAttributeNS(StringnamespaceURI,
                      String localName);

Arguments

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.

Returns

The value of the named attribute, as a string. If the attribute is not defined, this method is supposed to return an empty string, but some implementations return null instead.

Description

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.
