Problem with reading jQuery XML in IE

Problem with reading jQuery XML in IE

It works in Chrome and Firefox but not IE!  I really hate IE sometimes.  I have tested this with IE 9.

Essentially I have an XML formatted string:
var xmlData = '<?xml version="1.0" encoding="ISO-8859-1"?><details><test>hello</test></details>';

I am then trying to access this string using:
window.alert($(xmlData).find('test').text());  And returned is nothing.  What am I doing wrong?  The same code works fine on Chrome.
