Return rss feed from an angularjs route

I'm trying to create a frontend with angularjs for an app that generates rss feeds. So i want to configure a route that will render the rss.

So the basic idea is, when a user goes to http://myserver/#/myTopic/rss the server should return the result of the following api call http://myserver/api/1/myTopic/rss

So I created my route as below.

app.config(['$routeProvider', function($routeProvider) {
  $routeProvider.
    // render rss feed
    when('/:topic/rss', {
      controller: 'rssCtrl'
    });
}]);

And the rssCtrl is defined like this

var rssCtrl = function($scope, $location, $routeParams) {
  // what to put in it??
};
app.controller('rssCtrl', rssCtrl);

I'm conceptually stuck on what to put in my controller, since I don't want the index.html to be rendered (my single page app) but the rss feed.

Any ideas? thoughts?
