Re:  General trick for re-applying recursivly/iterative
Simply comparing the size of the input and the output file (and
calling the straightforward XSLT
script over again) might do the trick for pruning; if you need to
guard against replacment operations
that might not change the size, cmp or diff would provide an
indication of "no change".
