title: Mootools Element to HTML
body: <p>My question is quite simple.. I need to convert an Element object into an html string</p>
  
  <pre><code>var thumb = new Element('img',{'src':"big.jpg"});
  console.log( thumb.?????() ); //some magical method here
  </code></pre>
  
  <p>should return (as a string)</p>
  
  <pre><code>'&lt;img src="_big.jpg"&gt;'
  </code></pre>
  
  <p>I've tried the <code>.get('html')</code> but it returns nothing, obviously because the img tag has nothing inside.</p>
  
  <p>Thanks in advance</p>
