How can I create a swagger yaml contract to specify an end going that always returns a xml object

Question

How can I create a swagger yaml contract to specify an end going that always returns a xml object.

I have tried to create one but the object displayed is not 100% the same as what I actually get back.

the endpoint that I want to read / get the xml from is this

https://www.somecompany.com/xmlfeed/test.xml

Below is my swagger and below that is what I actual data read back.
