  <p>I am trying to use a regex expression to find the lines that match the following....</p>
  
  <ul>
  <li>Duplicate IP</li>
  <li>Duplicate Time</li>
  <li>Duplicate Filename</li>
  </ul>
  
  <p>I then want to delete these lines so only one remains, there is a filesize at the end that differs slightly otherwise I could just remove duplicate lines.</p>
  
  <p>I have managed to detect the IPs <a href="http://regexr.com?2vv5c" rel="nofollow">http://regexr.com?2vv5c</a>  but thats as far as I have got, can anyone help?</p>
