title: Regex to find http and .html
body: <p>I'm trying to find links in the following format:</p>
  
  <pre><code>http://subdomain.subdomain.domain.tld/subfolder/randomstring.html
  </code></pre>
  
  <p>Basically, I need a regex that looks for <code>http://</code> and stops looking when it finds <code>.html</code>. Everything in between shouldn't matter. I.e., more/less subdomains, variable TLD and variable folder.</p>
  
  <p>Is this possible?</p>
  
  <pre><code>((http://)?=(.html))
  </code></pre>
  
  <p>What I've got so far (not functional) is this. I'm really not familiar with the look-ahead assertion so I might be on the wrong track.</p>
  
  <p>Anyways, any help is going to be greatly appreciated!</p>
