Obtaining matched (sub)string

[Michael T. Davis]

When using m//, is it possible to obtain the (sub)string of the
target which actually matched the regex? For example, if the target is
"Get your viagra here" and the regex is "(cialis|viagra|xanax)", is there
a way to indicate that the match was "viagra"?

Thanks,
Mike

Err.. Yes. By examining the content of $1.

(Are there any spam crap any longer that spells out "viagra" in
cleartext?)

He may be working on "normalized" words, so his code _may_ be useful.

I must have tried that before when there was another error in
my code. It's working fine now.

Yeah, I still see all sorts of obvious "SPAM words" sent in the
clear.

That is, in fact, what I'm doing. The case I provided was just a
simplification.
