Generate xml with out outbound and capture

any possible options ? 

I believe you could create a Message Routing or Monitor Schedule using the flat file or XML file connector to save the output to a file for testing.

I also asked a member of the development team who said:

I think what you have mentioned is correct. A routing rule based on the baseline FileExtractHandler can be created to capture the XML output to a flat file.  Alternatively, HttpExtractHandler can also be used with and address such as putsreq.com for examine the XML output.

@Jon Reid ,

this is not satisfy our business purpose .i want to capture xml maps message and use this for other purpose (mentioned in original requirement) .
