You want to look into the function match-data abd friends.

For example, (match-string 3) gives you the part matched by the third
parenthesis in your regexp in the current buffer (if you're matching
against a string `str', you'd have to write (match-string 3 str).

Note that this gets you the text properties too - if you want to have
them filtered, you'd use (match-string-no-properties ...).

Hope that helps.
