A couple of years ago I wrote an XSLTDoc application
(http://www.jenitennison.com/xslt/utilities/XSLTDoc.zip) that includes
an XPath parser written in XSLT (xpath.xsl). The parser creates a
parse tree in XML. The application uses that parse tree to create
explanation for the expression, but I guess you could do other things
with it such as use it for evaluating expressions.

Anyway, I'm quite sure that it's by no means perfect and it does make
heavy use of the node-set() extension function. It would be a fair bit
easier to do with the regular expression support in XSLT 2.0 (though
not *very* easy, since you have to worry about matching brackets and
so on).

Cheers,

Jeni
