Well, the API has a pretty good explanation of how to use the Pattern and Matcher classes here:

http://java.sun.com/j2se/1.4.2/docs/api/java/util/regex/Pattern.html

The statement that you have commented out should work, but it's hard to tell without knowing what
your alphaRegex and value are.

Hi David,

The code you listed below looks ok.  This is not the more interesting
part of the problem though, if you like I suggest including a copy of
your regex.

I've used the regular expressions a bit and found them a bit confusing. 
It took me a little while to figure out the difference between Greedy
quantifiers, Reluctant quantifiers, and Possessive quantifiers.  I
forget what the differences are (sorry, its been too long) but I suggest
setting up a simple experiment so you can discover for yourself.  They
*are* quite a bit different.

Good luck!
