Well, you realize that this document is not valid per your schema (e.g.,
if you try to parse it back with validation enabled, you will get a
parsing error). To set text content for a DOM element you will need to
call setTextContent on that node (as opposed to on the document node
as you've done above):

DOMElement* e (dom_doc->getDocumentElement ()); 'stuff'
e->setTextContent (xml_data);


Also note that this is a question about DOM rather than XSD which this
mailing list is for. I suggest for question like this you use Xerces-C++
documentation[1], examples[2] and mailing lists[3]. In particular,
the CreateDOMDocument example does exactly what you've asked.
