Is `match-string' what you're looking for?

,----[ C-h f match-string RET ]
| match-string is a compiled Lisp function in `subr.el'.
| (match-string NUM &optional STRING)
| 
| Return string of text matched by last search.
| NUM specifies which parenthesized expression in the last regexp.
|  Value is nil if NUMth pair didn't match, or there were less than NUM pairs.
| Zero means the entire text matched by the whole regexp or whole string.
| STRING should be given if the last search was by `string-match' on STRING.
