Do you know any other way to do that? (Your example is using FIND
multiple times, and in a big string that would be many times
slower.)

I think that it is better to think of the problem in a different
way, because it allows you to understand things much better. If
you switch to think about grammars instead of patterns you'll find
out that your problems get simpler, not more complicated. IMHO.

Well, the 74-lines [X]HTML parser built into Temple is far from
being complete, but has been able to parse all the HTML files I've
fed into it until now. I don't think this is so much complicated,
you just need to avoid that brain-dead way of doing things that
seems to pervade the world. ;-)

Gabriele.
