> Also, using $2 as a loop condition smells a bit fishy
Indeed, the idiomatic expression is rather
while( m/REGEX/g ) {
... # use groups only if match successful
}
The only reason to check $2 separately, is to make sure it's not false ( "", 0, undef, etc )
this can be done with
while( m/REGEX/g ) {
last unless $2;
...
}
tho I doubt the OP is aware of all those false cases.

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).
