Starting jquery-1.4, in IE8, html() returns null for a non-HTML element (e.g. <xml)


In IE8, for the following HTML, $('#myXML').html() returns null starting jquery-1.4. This used to return the contents of the <xml> tag in jquery-1.3. Any ideas, how do I get the contents of <xml> tag? Thanks.
  1. <html>
  2.   <head>
  3.     <title>Title</title>
  4.     <script type="text/javascript" src="http://code.jquery.com/jquery-1.4.js"></script>
  5.   </head>
  6.  
  7.   <body>
  8.     <xml id='myXML'>
  9.       <node><value>some.value</value></node>
  10.     </xml>
  11.   <body>
  12. </html>
