title: Notepad++ regex group capture
body: <p>I have such txt file:</p>
  
  <pre><code>ххх.prontube.ru
  salo.ru
  bbb.antichat.ru
  yyy.ru
  xx.bb.prontube.ru
  zzz.com
  srfsf.jwbefw.com.ua
  </code></pre>
  
  <p>Trying to delete all subdomains with such regex:</p>
  
  <pre><code>Find:    .+\.((.*?)\.(ru|ua|com\.ua|com|net|info))$
  Replace with: \1
  </code></pre>
  
  <p>Receive:</p>
  
  <pre><code>prontube.ru
  salo.ru
  antichat.ru
  yyy.ru
  prontube.ru
  zzz.com
  com.ua
  </code></pre>
  
  <p>Why last line becomes <code>com.ua</code> instead of <code>jwbefw.com.ua</code> ?</p>
