     I learned most of what I know about regular expressions while I  
was learning Perl a few years ago. Most Perl books and tutorials  
include a small part that deals with RE's, but perhaps that's not  
gonna help you much.

     However, I find that the documentation for the Python "sre"  
module is quite good. You may want to have a look at it -- should be  
enough for what you have to do with this riddle.

(Also, note that however simple they may seem, one can never  
completely master regular expressions. There are entire books  
dedicated to the things, and when properly used, they're the most  
powerful text processing tool available for any language. In other  
words, try to remember what you'll learn about them: they're very  
useful.)
