title: How to add new item into srt file
body: <p>This is start of a <code>srt</code> file:  </p>
  
  <pre><code>0  
  00:00:07,000 --&gt; 00:01:00,000  
  lorem ipsum...  // this line doesn't work  
  
  1  
  00:01:02,960 --&gt; 00:01:05,800  
  lorem ipsum...  
  
  2  
  00:01:05,840 --&gt; 00:01:08,960  
  lorem ipsum...  
  </code></pre>
  
  <p>The first line doesn't work, I suppose because of<code>0</code> as the ordinal.<br>
  I need a way, javascript way if possible, to correctly change all ordinal numbers at once, not one by one (over 1000 lines), starting with <code>1</code> and not with <code>0</code>.  </p>
  
  <p>I was searching for various online solutions, without success.</p>
