как в xquery сделать выход из цикла?

DONE


The "for-loop" is not actually a loop, so there is no way of exiting it
- in functional languages you don't have that kind of flow control.

However optimising XQuery implementations will probably not evaluate the
whole loop if you just use parts of the result, e.g.:
> subsequence(for $i in 1 to 1000
> return $i,
> 1,
> 10)
will only evaluate the first 10 elements of the sequence from the for
loop as the others are not needed for the result of the "subsequence"
call.
