Be careful using .* as it is one greedy mother. The first .* will swallow everything up to the second last // in your regex.
So if your source text ever happens to have three or more sets of // on a line you regex will fail. Better to use nongreedy, minimal matching using .*?
This is probably so obvious to an expert like Corion, he didn't bother mentioning it. I mention it 'cos the OP states that the regex seems to work.

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).
