title: Notepad ++ - keep numbers only
body: <p>I have a text file containing numbers and characters (in arabic)</p>
  
  <p>like this:</p>
  
  <p>943894رنيش964737</p>
  
  <p>ترشقة1045051</p>
  
  <p>ضمنزلبالق10653</p>
  
  <p>to this:</p>
  
  <p>943894964737</p>
  
  <p>1045051</p>
  
  <p>10653</p>
  
  <p>I want to remove everything apart from the numbers</p>
  
  <p>I looked at a possible solution here:</p>
  
  <p><a href="https://stackoverflow.com/questions/8345388/find-remove-keep-only-numbers">Find/Remove (keep only Numbers)</a></p>
  
  <p>But its not working for me, plus its not very clear to me</p>
