regular expression control

Hi all,
I'm using regex with a list of regular expressions written by my 
team. They start from a set of rules and write down the expression
(s). What I'm requested to do now is a function that given a regular 
expression write down all the combinations available, with some 
limitations of course: if for example an expression has an infinity 
of combination this could not be achieved. Since all the expression 
have a limited number of combinations in this case a warning will 
suffice.
I searched for such a function in the regex code but didn't find it. 
Any idea?

Thanks,
Enrico
