Fair enough. I very rarely use regexes except as matchers and almost 
never for the sort of thing Eric is trying to do. In that case I'm far 
more likely to use one of the text parsing classes, though these often 
use regexes to decide what might be a keyword or separator.

In practise I use regexes far more frequently in SpamAssassin (a Perl 
application) or in awk scripts than I do in Java or C programs, and if 
its a really complex task I'll use Coco/R to generate Java from a BNF 
definition.
