... I'm still hesitant to post regexp responses until after I've tested them ...
I'd go farther than that. My experience is that whenever I do not test a regex, no matter how simple it may seem, it's guaranteed to be wrong! It's like some kind of corollary of Murphy's Law. For me, regular expressions are the most counter-intuitive concept in CS (or in C-what-we-laughingly-refer-to-as-S). I think I have a fairly good understanding of regexes and a fair body of experience with them, but I would never trust my untested opinion.

Are you posting in the right place? Check out Where do I post X? to know for sure.

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).
