Graphical Multi Mapping and then XSLT Mapping

Question

Hi I have to do message Split. I'm doing this message split. Then I have use XSL Mapping where I'm basically sending the whole Source message into Target Node. Basically Graphical mapping splits one Source file into 2 target files and XSL Mapping should move these individual files to 2 target messages. How Can I refer the Individual messages in the Mapping ?.
Since Actual message split takes place in Adapter Engine does XSLT Mapping acts on a Single message out of Graphical Mapping ( in my case Graphical mapping produces 2 messages  ) or It acts on both messages as no actaul split didn't took place yet in the Mapping runtime.
No Guess work please ..let me know if you actually did it.Appreciate all your help.

Message splits (1:n mappings) can be executed without BPMs. It will finally occur, as you said, at the Adapter Engine layer.
When you deal with multimappings with graphical mapping, XI will automatically create two new tags surrounding your root tag(s) (tag in case you have multiple occurrence of 1 interface; tags in case your target messages are from different interfaces).
But when creating multimappings with XSLT, ABAP or Java, you'll have to handle these two surrounding tags manually. So, in your xslt, your input will be like:
> <ns0:Messages xmlns:ns0="http://sap.com/xi/XI/SplitAndMerge">
>   <ns0:Message1>
>     <ns1:Your_Message1 xmlns:ns1="http://your.namespace1">...</ns1:Your_Message1>
>   </ns0:Message1>
>   <ns0:Message2>
>     <ns2:Your_Message2 xmlns:ns1="http://your.namespace2">...</ns2:Your_Message2>
>   </ns0:Message2>
>   ...
> </ns0:Messages>
(in case your target message is just 1 interface with multiple occurrence, you'll have only <Message1> tag with multiple occurence).
So, the secret here is that you'll have to handle the <Messages> and <MessageX> tags in your xslt code.
