Problems in exporting data to Excel from WebDynpro

Question

Hi,
I'm trying to transport data to Excel using the WebDynpro Binary Cache. The table data I have has certain special characters like & , < and > . I get an XML Parse error while trying to retrieve the XML List from the Binary Cache. The detailed error is Whitespace is not allowed. If table data is without these special characters Excel Export happens fine.
Any help is highly appreciated.
Thanks,
Bala

I got the same error message and find the solution (knowing that this is an old thread, but maybe in future it can helps someone)
I've changed my TableUtilities class (getting from this excellent blog: /people/sap.user72/blog/2006/05/04/enhancing-tables-in-webdynpro-java-150-custom-built-table-utilities), adding the CDATA Element
Method: DownloadToExcel
for (int j = 0;j<columnInfos.size();j++)
                         String attributeName = (String)columnInfos.get(j);
                         xml_file.append("<")
                                   .append(attributeName)
                                   .append(">")
                                   .append("<![CDATA[")
                                   .append(elem.getAttributeValue(attributeName))
                                   .append("]]>")
                                   .append("</")
                                   .append(attributeName)
                                   .append(">\n");
                    xml_file.append("</")
                              .append(_nodename)
                              .append("Element>\n");
