Re: [xsl] How to use the same expression in a match and a select test

yes or, in xslt 1 an entity

One use I have seen for entities in XSLT1 is as a proxy for function
definitions. Rather than having entities for xpath literals as in teh
examples here you can have an entity that expands to a boolean predicate
which you use as foo[&bar;] with teh predicate being evaluated each
time. Again though in xslt2 you can just parse the predicate once by
making it a function accessed like foo[my:bar(.)] which is often nicer
than using entity expansion.

or a key


or as I said, for xslt2 in the actual problem, at hand I'd use
for-each-group
