title: cut string after third occurence of <br> element with jquery
body: <p>I got a string as follows:</p>
  
  <pre><code>&lt;p class="remove"&gt;    
  This should go:
  &lt;br&gt;
  this too
  &lt;br&gt;
  &lt;br&gt;
  from here on I want it to stay
  &lt;br&gt;
  blabla
  &lt;br&gt;
  blabla
  &lt;/p&gt;
  </code></pre>
  
  <p>I want to cut the first part until the <strong>third</strong> occurence of <strong>br</strong> away with jquery.</p>
  
  <p>I know that I can get it by the split function, but I can't get it to get the third br element as the selector. </p>
  
  <p>Here is my code so far:</p>
  
  <pre><code>var replace = $('.remove').text();
  alert(replace.split('br:nth-child(3)')[1]);
  </code></pre>
