To get the ~~matched pattern~~ matched text you can simply do:

my $pattern = join '|', map "($_)", @patterns;
...
if ($line =~ /($pattern)/i) {
    print "matched $1\n";
  }

But be carefull if you want to get another matched text in this line. Somewhat it eats up all $1,$2,$3. Use $+ to get the last matched text of the line.

Edit: Sorry HV I should learn to read more carefully.

That shows you what text matched, not which pattern matched it. There's nothing wrong with it as a way of finding out what text matched, but in the node you replied to I was specifically trying to address this aspect of the root node: the whole point of this excercise is to figure out WHICH regexp matched.
