  <p>i want to search all that. For that i need a regex like: get me the word (acutally the number) after the word line. its always line. Since i've never worked with regex. Im reading me into it but until now i have had no luck with that.</p>
  
  <p>Im doing that on php. Please give me some input in that. :) thanks</p>
