- All Implemented Interfaces:
Function
4.1 string name(node-set?)
The name function returns a string containing a QName representing the expanded-name of the node in the argument node-set that is first in document order. The QName must represent the expanded-name with respect to the namespace declarations in effect on the node whose expanded-name is being represented. Typically, this will be the QName that occurred in the XML source....If the argument node-set is empty or the first node has no expanded-name, an empty string is returned. If the argument it omitted, it defaults to a node-set with the context node as its only member.
