title: Updating part of page with prototype and ajax
body: <p>i work with page using prototype, and i have to add some ajax requests, which updates content of one specified div.
  Here how i did it in jquery:</p>
  
  <pre><code>$j.ajax({
      url: url,
      success: function (result) {
          var resultDiv = $j(result).find('.SOME-CLASS');
          $j('.SOME-CLASS').html(resultDiv.html());
      }
  });
  </code></pre>
  
  <p>I tried to get the same result with prototype for last few hours and finaly i gave up. How would it look in prototype ? Its important to withdraw from result div with class SOME-CLASS and replace its content with existing in document div with the same class.</p>
  
  <p>PS.
  I thought about parsing raw result string recived from prototypes request to get content of  and then replace founded content with existing in document, but in my opinion this is bad, non elegant solution. Is there anything better ? I heard that prototype is great tool for DOM manipulation.</p>
