Sounds a bit odd, written like that.
Can you give us a bit more context?
Regexes aren't always the best way to go...

I have no idea why you would want to (or how) write a RegExp to count numbers for you ...

A simple while or foreach loop should be able to handle this for you, provided you use the \x escape for making the numbers hex.
