[jQuery] IE Reports 0 children()

[Nicholas]

FF works fine, IE however reports 0 children() and I am finding it
difficult to solve.

Example XML retrieve from $.get:
<?xml version="1.0" encoding="UTF-8"?>
<letter>
  <paragraph>text
     <paragraph>text
  </paragraph></paragraph>
  <paragraph>text</paragraph>
</letter>

The code:

jQuery.get("process.asp", {job:"getLetter", letterID:letterName,
type:"xml"}, function(xml){
        alert(jQuery(xml).children().length);
}

Have I got awry somewhere? Seems pretty straight forward. I've tried
removing the xml doc definition as well as the <letter> tags. IE
always reports 0 children.


Thanks,
Nick
