Hi,
In the MQInput node there is a Timing parameter that can be set to Immediate. Is there a similar parameter to the PARSE clause?
If not, you could force validation by climbing the entire tree and copy it to Environment. My understanding is that validation works 'on demand' (it's an IBM product, after all  ) i.e. it's only when you actually access a field that it gets validated.

This is the code I used to force validation of the message tree:
| Code: |
CREATE PROCEDURE WalkValidate(IN Input REFERENCE) BEGIN
DECLARE Ref REFERENCE TO Input;
-- Get the value of this field first
IF Ref IS NULL THEN
END IF;
-- Walk through the first child
MOVE Ref FIRSTCHILD;
IF LASTMOVE(Ref) THEN
CALL WalkValidate(Ref);
END IF;
-- Walk through the next sibling
MOVE Input TO Ref;
MOVE Ref NEXTSIBLING;
IF LASTMOVE(Ref) THEN
CALL WalkValidate(Ref);
END IF;
END; |

OK, so the IF Ref IS NULL accesses the field and thus validates it. No need for Environment then...

hi
thanks for ur help, it works with the following statement
CREATE LASTCHILD OF OutputRoot DOMAIN('MRM') PARSE(InMsgBlob SET MsgSetChr OPTIONS BITOR(ValidateValue, ValidateContent, ValidateImmediate, ValidateException));
The only clause that I missed earliear was 'ValidateImmediate'. As per document, this is the default option that will be used, but I think, it does not happen.
Now I included this 'ValidateImmediate', it is working fine. The flow raises exception at this stage itself (immediately) for invalid XML.
thanks |
