Acquiring an XML object using Mediator
Handling a synchronous reply is easier as we have only one element to deal with, that is,
the URL of the actual execution plan. Here as well, we have to use transformation with
one simple concatenation function to combine our oramds: path with the
<EP>.xml filename; you can see it in the following screenshot. Now, back to the Medi-
ator routing rules and transformations presented earlier in the chapter, you can see more
clearly how we transform our Execution Plan as an XML object.
The next operation in the row Assign: Retrieve_ExecutionPlan is just to as-
sign the whole of the reply to the EP type in the Messages Process header. (Yes, "retrieve"
probably is not the best term here as it is in fact an inject, but you get the idea.)
