Remove URL regardless of format
<p>Having a brain freeze...</p>

<p>Have a URL which may be in any of the formats : </p>

<pre><code>http://url.com/stuff
url.com/somestuff
www.url.com/otherstuff
https://www.url.com/morestuff
</code></pre>

<p>You get the picture.</p>

<p>How do I remove the .com part to leave just the various 'stuff' parts ? For example, the above would end up : </p>

<pre><code>stuff
somestuff
otherstuff
morestuff
</code></pre>
