Excel export problem in grid

I generate xml string using java template and form a grid in JSP using that xml sting.The excel export doesn’t launch when any one of grid cell contain “degree symbol” . Otherwise it’s working fine. if any one have idea for this problem?

The content of debug_xxx.xml

An invalid character was found in text content. Error processing resource 'file:///C:/Apache2.2/htdocs/phpapp/excel/debug_2…

The XML string has special char degree symbol ( 15°).

The XML string is

<?xml version="1.0" encoding="iso-8859-1" ?>IDLocation IDLocation ID loadTypeStatusPart #Part DescriptionRef Qty %Curr QtyAlloc QtyMin QtyMax Qty971011-A-001-A-3<![CDATA[Edit Location 011-A-001-A-3]]>Pick FaceActive664.819PATRIOT Continental Large Trial 15&deg;, 19mm701501050

Hi.
Could you describe in details how export doesn’t work?
Does server generate any error or request isn’t sent from browser to the server side?
I checked locally that degree symbol was processed correctly.
Try to use online export service:
