My company has thousands of existing xml web services and is starting to adopt AngularJs for new projects.
The tutorial over at http://angularjs.org/ uses json services exclusively. It looks like they make a service call in the controller, parse the resulting JSON, and pass the resulting object directly to the view.
What do I do with XML? I see four options:
If option 2 is relatively easy for you (like adding one-line JSON conversions in your back-end controllers, for example), then it's probably a good investment, as the JSON is leaner over the wire, far less work on the client side and generally preferred by RESTful API consumers (in case there are other consumers).
