Implemented Interfaces:
Function

public class LocalNameFunction
extends java.lang.Object

4.1 string local-name(node-set?)
The local-name function returns the local part 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 or the first node has no expanded-name, an empty string is returned. If the argument is omitted, it defaults to a node-set with the context node as its only member.
