I need to perform the following operation on regular expressions:
I have a string, say, bFFacdABCf, that matches a pattern, say, ab!acd!fac , where ! is a sequence of any letters. I want to be able for each match to create the following pair:
! - FF
! - ABC ...etc
Is there a special variable that can be used as a result of matching? If not, what's the way to do this?
