Thats known as matching on "result tree fragments" and is explicitly
forbidden in the current draft. Basically the argument against it was that
it introduces multi-pass capabilities into XSL, and reduces the ability to
do incremental implementations. Personally I don't find this very
convincing - string processing gives raise to the same problems as result
tree matching.

It should be possible, though. I've posted a few months back an XSL program
which solves the n-queens problem by abusing the string operations - if you
look it up you could probably get some ideas on how to achieve what you
need. I'd be wary of actually using such code in a real system, though. I'd
prefer to chain two XSLT stylesheets instead.
