I am using jQuery to work with XML documents that are parsed in the browser. However using the .attr(String) method fails with an error in IE.

I have tracked down the problem, which appears to be different implementations of 'getAttribute' between the HTML DOM and XMLDOM in IE.

I have attached a patch with a test case and my fix. Unfortunately the fix consists of catching the error and calling the other version of the function, which seems a bit clunky.

Oh I forgot to say the patch is against SVN revision 361.
