Hi,
I had a design issue.
May be simple for you.
I had a input queue for my message flow.
I am putting totally different xml messages in the input queue.
Now, issue is how I should some how find out inside message flow which XML I am receiving?
I am thinking of using RFH2 for this.
Please let me know your valuable feedback on this.
Thanks,
Prasanna |

| You can test if a tag exists in the XML using the cardinality, as I understand it, so you could use filter nodes checking the cardinality of tags unique to each XML to separate the messages into different flows, providing the content is recognizably different. Am I making sense? (This is the mothod I'm using anyway) |

Suppose your 4 xml messages have the root element as A, B, C and D
Then in your compute node you can write something like :
If InputRoot.XML.A IS NOT NULL THEN
SET InputLocalEnvironment.Destination.OuterList.DestinationData.labelname = 'Msg1';
End if;
If InputRoot.XML.B IS NOT NULL THEN
SET InputLocalEnvironment.Destination.OuterList.DestinationData.labelname = 'Msg2';
End if;
If InputRoot.XML.C IS NOT NULL THEN
SET InputLocalEnvironment.Destination.OuterList.DestinationData.labelname = 'Msg3';
End if;
If InputRoot.XML.D IS NOT NULL THEN
SET InputLocalEnvironment.Destination.OuterList.DestinationData.labelname = 'Msg4';
End if;
Now you connect the output of the compute node to a Route To Label node , Have 4 Label nodes with the names as Msg1, Msg2, Msg3 and Msg4
and connect your compute nodes to these Label nodes.

Or could have client program set some kind of indicator in MQMD.ApplIdentityData and then within your message flow route to different paths to handle different types of messages.
