You could use the "positional variable" feature of the "for"
construct, but you'd get results other than what you want because the
"position" is assigned before any filtering by the "where" clause and
reordering by the "order by" clause.
However, you could use this feature with a nested "for":
for $y at $i in
(for $x in doc("books.xml")/bookstore/book
where $x/price>30 order by $x/title return $x/title)
return concat($i, ": ", $y)

order by $x/title
return $x/title
If "doc("books.xml")/bookstore/book" returns 3 elements(book1, book2, book3),
and during the looping, I want to get loop counter value.
For the first element, I want to prepare string using loop counter like
"elem-1", and for the second, I want "elem-2"
Thank you for your help.
