Thanks Jarno, true enough. So to return the third node from the following: <node> </node> <node> </node> <node>test</node> I'm going to use: string(translate(., '  ', '')) Any improvements, suggestions on that? I can't think of any other whitespace (well, apparent whitespace) characters... cheers andrew
