Thanks I'll take a look.

I think what I thought I could do is not possible.  Apparently you can't 
get multiple capture groups without multiple sets of parenthesis.  I 
thought I could do something like;

Pattern.compile("(the)*") and capture all of the 'the's in the string in 
their own group.  But as it turns out each group must have its own set 
of parenthesis.

So instead of that approach I decided to use Matcher.find() to search 
through the string and keep a list of the matches.

I'll post some code once I've got it cleaned up and debugged.
