Unfortunately, the CDATA sections solution breaks if the nested document also includes a CDATA section. The only complete solution is to encode the nested document, either as bas64, or just escape dangerous constructs. I prefer just representing it inline, and 'escaping' the xml-decl to be something like "<?x-xml ...". If there is a potential for a doctype decl, you are better off just using base64, as trying to escape a DTD is quite tricky. -derek > -----Original Message----- > From: Bornholtz, Tim [mailto:Tim.Bornholtz@e...] > Sent: Wednesday, December 29, 2004 11:55 AM > To: Jean-Noël Colin; xml-dev@l... > Subject: RE: Embed an XML document in another XML document > > If you really need to have any sort of content within your body then you > can define the body tag to contain a CDATA section.
