Dataprocessor uploadFromXML

mygrid.updateFromXML(‘xmls/rules/template_fees.php’);
This is not working in my code of php . Let you people know that template_fees.php contains xml

Only requirement - template_fees.php must provide data in correct grid-xml format. There is no any specific to updateFromXML options or format details.

the xml format is fine what might be the other reason

Is problem occurs in both IE and FF?
