If you
really need to hang on to the //gmc regex construct then you could opt to include the regex's as alternatives. Afterwards split the grouped result per regex based on field position in the group.
Update:
- note that the order of the alternatives influences which one will match first each time (and that's what you wanted right?)
- since the total regex is just one expression your program will examine the text only once -> performance gain
See below for an example to get the idea.
#!/usr/bin/perl
use strict;
use warnings;
my $text = <<TEXT;
Title: The Moor's Last Sigh, Author: Salman Rushdie
Title: The God of Small Things, Author: Arundhati Roy
Title: A very special title, Author: varianf varians
TEXT
my @answers;
my $re = qr/Title: (.*?), Author: (\w+) (\w+)$/; # 3 groups here
my $re2= qr/Title: (.*?special.*?), Author: (\w+) (\w+)$/;
my (@MatchAll) = ($text =~ /$re2|$re/mgc);
my (@Match1,@Match2);
for (my $i=0;$i<@MatchAll;$i=$i+6) {
defined $MatchAll[$i] && push @Match2, $MatchAll[$i..$i+2];
defined $MatchAll[$i+3] && push @Match1, $MatchAll[$i+3..$i+5];
}
Output:
$ perl reg.pl
.$VAR1 = [
'A very special title',
'varianf',
'varians'
];
$VAR1 = [
'The Moor\'s Last Sigh',
'Salman',
'Rushdie',
'The God of Small Things',
'Arundhati',
'Roy'
];
P.S.: I hardcoded the boundaries for the captured fields to shortcut the coding here. Naturally this part could/should be coded more flexible if you deal with a lot of regex's.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
