$.Ajax request is not working in Chrome

$.Ajax request is not working in Chrome

I'm really having trouble to put it to work in Chrome. It runs great in IE and Firefox.

Here is the code:
  1. $.ajax({url: "../requests/get_xml_oid.php?oid=" + key + "&host=" + Servidor + "&dti="
  2.                     + document.getElementById("dtinicio").value
  3.                  + "&dtf="
  4.                  + document.getElementById("dtfim").value,
  5.                     method: 'GET',
  6.                     success: onDataReceived,
  7.                     error: function(XMLHttpRequest, textStatus, errorThrown) {
  8.                     alert(textStatus+" - "+errorThrown);
  9.                     }
  10.                 });

The return of get_xml_oid.php is in XML.

Chrome Error:
  1. Uncaught TypeError: Object #<a Document> has no method 'search'

What's going on?

Thanks,
