Using your example in an assignment step:
let $this :=
The output would look like this:
No, you are talking about the output of the expression in an assignment step. However, I was asking about the output of the process itself in postman for example.
The output of the process, if a request to the process is sent with Accept header application/xml, will still include the <*process name*Response> tag.
You can use whole payload instead of variable as field ,
This should help .
Else you have to use BPEL process to design the custom response without tags.,
