extends java.lang.Object
4.1
string namespace-uri(node-set?)
The namespace-uri
function returns the namespace URI of the expanded-name of the node in the
argument node-set that is first in document order. If the argument
node-set is empty, the first node has no expanded-name, or the namespace URI of
the expanded-name is null, 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 by the namespace-uri function will
be empty except for element nodes and attribute nodes.
