Subject: Re: embedded code construct a la perl

I want to find all nested pattern matches in a string, and execute some 
code at each match. This should include searching all nested substrings 
of a match. I realize I could do this in perl ( I have been up to now), 
but my code is getting quite complex and I would like to implement an 
object model (something I could also do in perl, but works much better 
in Ruby).  In perl, I was able to do this in a regexp (example below). 
Can I do the same thing in ruby, or will I need to use some sort of loop 
to wun code at each match.

Thanks.

Vince
