Copy this code and paste it in your HTML 
  1. <p id="apple">Apple</p>
  2. 	<p id="banana">Banana</p>
  3. 	<p id="cherry">Cherry</p>
  4.  
  5. 	<script type="text/javascript" charset="utf-8">
  6. 		// this works
  7. 		x=$$('banana').addContent('foo');
  8.  
  9. 		// so does this
  10. 		y=$(x.next()).addContent('bar');
  11.  
  12. 		// but this is null, because this object doesn't have any DOMAssistant methods e.g. addContent
  13. 		z=x.prev().addContent('baz');
  14.  
  15. 	</script>
