id - XPath

XSLT/XPath Reference: XSLT elements, EXSLT functions, XPath functions, XPath axes

The id function finds nodes matching the given ids and returns a node-set containing the identified nodes.

Syntax

id( expression )

Arguments

expression: If expression is a node-set, then the string value of each node in the node-set is treated as an individual id. The returned node set is the nodes corresponding to those ids.

If expression is a string, or anything other than a node-set, then expression is treated as a space-separated list of ids. The returned node set is the nodes corresponding to those ids.

Returns

A node-set containing the node or nodes identified by the given id or ids.
