Just tried to use [nodeName=namespace:node_name] syntax in Firefox and Chrome to get a result message from a soap responseXML and failed while using jquery-1.6.2.min.js and jquery-1.7.1.min.js:

This is the contents from my jQuery.ajax "success:" blocks code

success : function(resp) {
      var res = $(resp).find('[nodeName=ns1:result]').text();
      $('#response').text(res);
     }

Apparently this no longer works http://bugs.jquery.com/ticket/10377 and they aren't inclined to fix it because. There are so many problems getting it all to work in multiple browsers.

My fix was to go back to jquery-1.4.2.js which works.
