[jQuery] not able to append new tag in XML in IE

[g...@iec]

I am making an ajax call and in response, i am getting an XML.
And then using data from XML, i am creating a form.
I stored response XMl in a variable like this
 var xmlData  = $(data);
If there is any change in any field of  form then i am changing
corresponding node value in xmlData
by appending new node in related node like this :
 var val = document.createElement('{nodename}');
$(val).text({changed value});
$({corresponding node}).append($(val));

This is working fine in FF but not working in IE.

Kindly guide me how can i solve this problem.

Thanks in advance to all for providing guidance.
