local-name Function

Article
2011-02-21

Returns the local part of the expanded name of the node in the node-set argument that is first in document order.

string local-name(node-set?)

Remarks

An expanded name typically consists of a namespace URI (or associated prefix), a colon (:) and a local part. For example, b:author is an expanded name, where b is the namespace URI prefix and author is the local part. So applying the local-name() function to this node returns author. When a node has no expanded name, such as author, applying the local-name() function on this node returns the node name as is, i.e., author.

If the node-set argument is omitted, it defaults to a node-set with the context node as its only member.
