is not absolutely clear what you want to do, something like the following may be useful: I'll try to explain a little better what I'm getting at... I want to write a expression that does something like this... takes a sequence like this ("Page1","Page2","Page3") and outputs Page1 > Page2 > Page3 so, assuming the sequence is in a variable $pages we try something like this... for $p in $pages return concat( $p, ' > ') but of course, this causes a trailing ' > ' which we don't want... so something like is what I'm looking for for $p in $pages return concat($p, if (---sometest---) then '' else ' > ' ) problem is, I can't figure out how to write an expression that can tell if this is the last item in the sequence. Does that explain it a little better? -- John McGowan Seven A C Consulting, Inc.
