You can use xdmp:set to set a variable to a certain value if you
achieve/find what you're looking for before you finish processing all
items, then 'skip' the rest of the items:
let $done := 0
for $i in $items
return if $done = 1 then () (: do nothing for all the rest of your
$items
else (: do your processing on this item :)
return if ($found-what-you-were-looking-for) then
xdmp:set($done, 1) else ()
But Ken's way is better (as usual), whenever possible.

There is no such "break" construct in XQuery. You have two choices to
reduce the number of tuples that are acted on in the "return" clause:
(1) - use a predicate when selecting the values creating tuples
(2) - use a "where" clause to toss out created tuples that you don't
want
Rather than break out of the processing of everything, you need to limit
the processing to only those values you want processed. Because
*everything* you select gets processed.
I hope this helps.
