  org.ucl.xpath.function.Function
      org.ucl.xpath.function.FnStringJoin

public class FnStringJoin

extends Function

Function to join strings together.

Usage: fn:string-join($arg1 as xs:string*, $arg2 as xs:string) as xs:string

This class returns a xs:string created by concatenating the members of the $arg1 sequence using $arg2 as a separator. If the value of $arg2 is the zero-length string, then the members of $arg1 are concatenated without a separator.

If the value of $arg1 is the empty sequence, the zero-length string is returned.
