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...

for $cnt in  count(  $pages )
            return
                (
                   ( for $cnt2 in $cnt,
                         $p in 1 to $cnt2 - 1
                            return
                               ($pages[$p],   '>')
                    ),
                    $pages[$cnt]
                 )

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?
