Perl Regex Question

Name: Anonymous 2012-02-26 1:44

I've been using /e to execute code with something I've captured in regular expressions. Like so:

$string =~ s{(tExT)}

            { do_something($1) }eg;

However, I've been wondering if there's anything else I can do in there. Like for example, could I use if-statements in there?

Why don't you try it instead of asking?

Because I tried it, and it didn't work. But I was wondering if there was a way, but I was just doing it wrong.

Using $& to try to check for matches was tricky, but I got it now.

Well if it didn't work then it doesn't work I guess.

Gee did you ever learn the Scientific Method when you went to school or didn't you go at all?

You don't even have any idea what he's talking about. Why do non-programmers come to /prog/ and pretend to be hardass.
