remove illegal files from the XML (#644)

Browse Source 
according to the SAP note 1750204 we can use the method IF_IXML_OSTREAM->SKIP_NON_XML_CHARACTERS to strip out illegal characters for XML rendering.
Since this method needs a kernel version with builtin support, I've made the call dynamically in a try/catch block to support systems with a lower kernel too.

This patch fixes the issues from #298 (at least for us)
