For something of a simpler* solution, but in the same vein, there's HTML::TreeBuilder. HTML::Element provides all of the primitives that you really need for an operation like this: look_down to identify relevant elements, replace_with_content to "remove" a tag without removing what it contains, and delete to completely destroy all signs of a given element. I'm not up to writing an example right now, but it's truly simple. Give it a shot! It goes a long way, and the output is bound to be less of a mess than the input.
* edit: okay, I realized that some might be confused by this usage of simple, since trwww's example is pretty simple in itself. Mostly it's a matter of being allowed to think in terms of tree manipulations instead of opens and closes and stacking and de-stacking. The corresponding cost is in storage, but it's usually not worrisome.

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).
