If you can first transform your XML document into a DOM,
you may find "xsl-pattern" useful.
"xsl-pattern" is an implementation of the XSL pattern subset
(which is a XQL subset) -- see

Recently, 4XSL has been announced on this list (look into the
archive). At the time of the announcement, only match patterns
had been implemented. But, this may have changed meantime.
