Thank you very much. So I cannot get individuals without removing the repetition and do a while ()... i.e.
use strict;
use warnings FATAL => 'all';
my $string = "aacbbbcac";
my $re1 = qr/((a+)?(b+)?(c))/;
while ($string =~ /$re1/g) {
foreach (0..$#-) {
printf "Group %d: <%s>\n", $_, defined($-[$_]) ? substr($string, $
+-[$_], $+[$_] - $-[$_]) : '';
}
print "\n";
}
Bad news for me, but again mega thanks for your very clear answer.
ps:
Group 0: <aac>
Group 1: <aac>
Group 2: <aa>
Group 3: <>
Group 4: <c>
Group 0: <bbbc>
Group 1: <bbbc>
Group 2: <>
Group 3: <bbb>
Group 4: <c>
Group 0: <ac>
Group 1: <ac>
Group 2: <a>
Group 3: <>
Group 4: <c>

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).

are good places to start.
