I'm not sure I see where the problem is, assuming the bytestream does not contain ]]>. The parser will look for the ]]> that delimits the end of the bytestream, and what was contained within the delimiters is the bytestream. If the bytestream is binary, I think I would encode it with Base64, and then decode the parsed content for delivery to your application. I don't see why you'd have to escape the ]]>. But perhaps one of the heavyweights will weigh in here and correct me! ;^) Regards, Mike Sharp "Cardona, Peter" <Peter.Cardona@u...> on 05/17/2000 04:58:19 PM To: "'xml-dev@x...'" <xml-dev@x...> cc: (bcc: Mike Sharp/Lante) Subject: arbitrary bytes/characters? All- (Sorry if this is a FAQ; I just subscribed to this list and the link to the archives on xml.org is broken. I'm also very new to the XML stuff!) I'm building a system that needs to deliver arbitrary byte streams and descriptions of those streams to client software. Most of the conversations between client and server use XML to encode requests and replies. My approach was to embed the byte stream inside a CDATA section of an XML document. But this appears to be impossible to do reliably: 1. The sequence "]]>" may not appear in byte stream, so I'd have to escape it with "]]>". That, of course, adds processing time to both the client and server in this communication. 2. If the sequence "]]>" were to appear in my byte stream as actual content, then what? I don't see a way to escape the escape. As I see it, to carry arbitrary bytes, a document must either specify how many bytes/characters to consider as a byte stream, or the escape operation needs its own escape (e.g. in C, '\' starts an escape sequence, '\\' means plain backslash since those are allowed too). Am I missing something or is XML just not able to do this? -PC *************************************************************************** This is xml-dev, the mailing list for XML developers.
