Hello, I have two questions regarding XML messages.
Message set for the output message:
Default Wire Format: XML1
Runtime Parser: MRM
"DATA" is one of the message elements.

I have a compute node with the following esql instruction:
SET OutputRoot.MRM.DATA = '<![CDATA[' || InputBody.MSG_HEADER
but the result I am getting is: <DATA><![CDATA[0074
I want to know how can I avoid the character "<" for being substitute by "&lt".

And the second question is how can I include "empty" xml tags in the output message. By "empty" I mean that I need the xml tags to be present in the output message even if they dont have data associated.

Thank you for your help.

The special value element 'AsisElementContent' will prevent the '&' from being converted to its escape sequence, however it may be a valid constant for the XML parser only, and not the MRM parser.

I believe the 'Create Field' statement will create an empty XML element.

Actually, the way that the documentation says to create an empty element is to use the VALUE clause of SET to assign NULL to the value of the element.

Thank you for your answers.
To solve the problem with the special characters I used a compute node with REPLACE statetments, I was not able to use de asiselementcontent because the parser is MRM.

DECLARE LESS BLOB CAST('<' AS BLOB CCSID InputRoot.MQMD.CodedCharSetId);
SET "OutputRoot"."BLOB"."BLOB" = REPLACE("InputRoot"."BLOB"."BLOB", LESS, X'3C');
