Hello
I need to embed an XML document inside another XML document. I read the XML document to embed as an incoming message and then set that entire message to a single field in the outgoing message.
The code shown works fine as long as the incoming XML document contains no special fields such as a comment containing a DOCTYPE. The embedded XML document is escaped as I expect.
So if I have leading DOCTYPE statement, I am assuming that InputRoot.XML will have two children, the first being the DOCTYPE and then the actual document. If the DOCTYPE is present, the write to the outgoing queue fails. It looks as if the XML parser is attempting to parse the comment field even though it is escaped (and of course this is not valid XML).
Error: Invalid Target.
The target element must be a name element and may not have a value. In addition, the element must not be marked as 'special'. The supplied element has name '', type '100663320', and value 'DOCTYPE etc etc
I have tried using AsIsElementContent - same problem.
Anyone tried to do this before?
| Code: |
declare xmlBodyRef reference to InputRoot.XML;
move xmlBodyRef firstchild;
declare xmlBody character '';
while lastmove(xmlBodyRef) = true do
set xmlBody = xmlBody || cast (ASBITSTREAM(xmlBodyRef OPTIONS FolderBitStream)
as CHARACTER CCSID InputRoot.MQMD.CodedCharSetId ENCODING InputRoot.MQMD.Encoding);
move xmlBodyRef nextsibling;
end while;
set OutputRoot.XML.MyMessage.messageData = xmlBody;

Put the embedded XML in a CDATA field instead of a plain body field.

FYI - this works
| Code: |
-- build the incoming message into a blob string
declare xmlBodyRef reference to InputRoot.XML;
declare xmlBody blob cast('' as blob);
move xmlBodyRef firstchild;
while lastmove(xmlBodyRef) = true do
set xmlBody = xmlBody || BITSTREAM(xmlBodyRef);
move xmlBodyRef nextsibling;
end while;
-- xmlBody should now hold all elements of the message
-- copy it to the messageData field
set OutputRoot.XML.MyMessage.messageData.(XML.Content) = cast (xmlBody
as CHARACTER CCSID InputRoot.MQMD.CodedCharSetId ENCODING InputRoot.MQMD.Encoding);

You really should use ASBITSTREAM instead of BITSTREAM, as I understand things.
And you could save some cycles by specifing the CCSID and ENCODING parameters of the ASBITSTREAM function instead of doing an additional CAST.
Maybe what you're seeing that's making the difference is the (XML.Content) descriptor.
