namespace-uri Function
Returns the namespace Uniform Resource Identifier (URI) of the expanded name of the node in the node-set argument that is first in document order.
string namespace-uri(node-set?)
Remarks
If the node-set argument is empty, the first node has no expanded name or the namespace URI of the expanded name is Null and an empty string is returned. If the argument is omitted, it defaults to a node-set with the context node as its only member.
Note
The string returned will be empty except for element nodes and attribute nodes.
