body: <p>I have a textfile contains lines with below:</p>
  
  <pre><code>IP              Ports           
  1.160.0.224     8080            
  1.160.1.49      8080            
  1.160.1.70      8080            
  1.160.1.170     8080            
  1.160.1.239     8080            
  </code></pre>
  
  <p>I want to use notepad++ regex to remove all empty space and just leave the IP:PORT.</p>

  <pre><code>1.160.0.224:8080
  1.160.1.49:8080
  1.160.1.70:8080
  1.160.1.170:8080
  1.160.1.239:8080
  </code></pre>
