I did just that and I can see the light!

Using the GNU Java regex package it was easy, but ended up slow.

Now I use ORO matcher and that's O.K. speed. Had to do some
tricks with a wrapper class to make it easier on the XSLT side
and to make regex matches be part of template match patterns
at all (can't refer to a variable in template match patterns.)

I am ready to switch from AWK to XSLT for my up-translation
project and will report more when I'm a good deal ahead.

Eventually some lower level XSLT support will be needed for
tail-recursion elimination and to avoid excessive copying of
strings and substrings of a (long) text node. Will have
proposals / requests within a month or so.

But the proof of concept is in the making. I'm developing
some use patterns. Up-translation with XSLT will be common
place a year from now.

And saxon is great!

cheers,
