Don't you just wish that repeat counts would repeat enclosed captures? Then you could use
m[
( ^ [^(:]+ )
(?:
(?: \( ( \d+ ) \) )?
:
(?: .*? \( ( [^)]+ ) \) ){1,}
.*
)?
$
]x;
to grab repetative elements instead of having to do
(or rather not do) things with built in limits, like this.
#! perl -slw
use strict;
while( <DATA> ) {
chomp;
my @bits = grep{ defined }
m[
( ^ [^(:]+ )
(?:
(?: \( ( \d+ ) \) )?
:
(?:
.*?
\( ( [^)]+ ) \)
(?:
.*?
\( ( [^)]+ ) \)
(?:
.*?
\( ( [^)]+ ) \)
(?:
.*?
\( ( [^)]+ ) \)
)?
)?
)?
)?
.*
)?
$
]x;
print join'/', @bits;
}

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).
