I have a scenerio where a filter node can receive either BLOB or XML format, it route on the basis of format(BLOB or XML). How can i identify that what format is it for incomming message?
Thanks in advance |

Since you have control over your message flow, I'd suggest that you add an ESQL statement to set domain name into some field in MQMD header,
In your XML path,
SET OutputRoot.MQMD.ApplIdentityData = 'XML';
In your BLOB path,
SET OutputRoot.MQMD.ApplIdentityData = 'BLOB';
Now, in your Filter node you could check for this field to know whether you are processing XML or BLOB message before routing it to appropriate terminal.

Kirani,
I do not have conrol to set MQMD since data is comming from client side in either format, however we are already using AppIdentityData for another parameter which is common to both format, any other lead will be appreciated?
Thanks |

What do you mean by BLOB data here? Is it in MRM-CWF format or is it simply binary data (Hex chars)?
Alternate solution would be to use some other field in MQMD header (MessageType, ApplOriginData, ...) to identify Message Type. If this is not possible then there is one more way of doing this in a message flow,
Read your input message as BLOB using your MQInput node, In a filter node check for '<' char in the beginning of the message, all XML messages start with < char 
| Code: |
IF (SUBSTRING(CAST(InputRoot."BLOB"."BLOB" AS CHAR CCSID Root.Properties.CodedCharSetId ENCODING Root.Properties.Encoding) FROM 1 FOR 1) = '<') THEN
-- Your message is XML
ELSE
-- your message is BLOB or ...
END IF;
|
I hope this helps.
