Getting the content on a div using class name

Getting the content on a div using class name

I have my php script return this huge html  http://jsfiddle.net/thiswolf/H8HTX/ but i am only interested with the content of the div with the class name one.

This is the code i am using on success

  1. success: function(html){
  2.                var ifilter = jQuery(html).find('.one').html();
  3.                alert(ifilter);          
  4.   }

  The code does not filter as i would have wanted.
