title: Notepad++ find all regular expression with condition
body: <p>Title is pretty much self explanatory...</p>
  
  <p>I want to find a particular match but with condition.</p>
  
  <p>I will give an example so it would be more clear:</p>
  
  <pre><code>http://www.example.com//test.htm
  https://www.example.com/test.htm
  https://www.example.com///test.htm
  ftp://www.example.com//myFile.jpg
  </code></pre>
  
  <p>I want to find all // but except the the http://</p>
  
  <p>so iow...</p>
  
  <p>if there is a <code>:</code> character (http://) before the <code>//</code> ignore it...</p>
  
  <p>return only matches that do not have <code>:</code> before <code>//</code></p>
