How do I transmit an XML document via SOAP?

Hi,

I am developing a web service in C# 3.0 that extracts an XML document out of an Oracle 11g database and sends the entire document back to the client. I have tried sending and XMLNode via SOAP and noticed that it strips out XML processing instructions (<? & ?>) and document type definitions (<! & >), becuase they are not allowed in SOAP. WIth that said, how can I encode the XML file and be able to send it back to the client without modifying its contents?

Thanks,
Pat

Usually if you don't want content to be processed, it would need to go in a CDATA element.

Example
<![CDATA[<client>Smith & Barney</client>]]>

Thanks Bob.

I do not want to modify the XML document after retrieving it out of the database. Is there an encoding method that I can use to send it via SOAP?

Pat,

Can you tell me how you are "extracting an XML document out of an Oracle 11g database and sending the entire document back to the client"?

Sure. I have the XML document stored as an xml type in oracle. I have an XQuery statement to return the XML document, and then I have an XMLNode as the return type on my web service. When the client gets the XMLNode it has the processing instructions parsed out.

Thanks,
Pat

Does the SOAP envelope enclose strings with CDATA?

Or, even better would be to wrap the XmlNode in a CDATA data, without modifying the source XML.
