Element.getAttributeNS( ) — get the value of an attribute that uses namespaces

Availability

DOM Level 2 Core

Synopsis

String getAttributeNS(String namespaceURI, 
                      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 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.

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.
