How to make facebook FQL query response in XML format?

Answer 1

You would have to have set your API Client's mode to XML. By default, it is responding in JSON these days (and the PHP client converts that to a PHP Array) but if you look at the API Test Console, you will see you can set the response mode of the client from XML, JSON, and what the PHP client returns.
