Not really. How would you do "return the subsequence of $S before the first
element that has @page='2'"?

It has to be higher-order.

Any solution that involves first finding the index position of the first
element that has @page='2' and then selecting by position is a bit of a
hack, and a solution that involves recursion is beyond the abilities of 90%
of the user base.
