title: Remove content between HTML tags in PHP?
body: <p>I would like to remove all content (between tags) from a HTML string.
  Is there an elegant way to do this without writing complex regex?</p>
  
  <p>If you want, I am actually looking for the <em>opposite</em> of what <code>strip_tags()</code> does.</p>
  
  <p>Suggestions?</p>
