      org.ucl.xpath.function.FnData

public class FnData

extends Function

fn:data takes a sequence of items and returns a sequence of atomic values. The result of fn:data is the sequence of atomic values produced by applying the following rules to each item in $arg: - If the item is an atomic value, it is returned. - If the item is a node, fn:data() returns the typed value of the node as defined by the accessor function dm:typed-value in Section 5.6 typed-value Accessor in the specification.
