Re: How to preserve numeric entities when converting xml String to a org.w3c.dom.Document ?

The simple answer is "Sorry, but those two forms are absolutely identical 
in meaning as far as XML is concerned. If you're going through XML-based 
processing, either output is correct. Standard tools aren't going to 
maintain this distinction."

The longer answer is that you could postprocess the XML-syntax text, or 
write your own serializer, to force the output into this form.
