App.factory('XmlToJsonSvc',
		[ '$http', function($http) {
			return {
				get : function(path, callback) {
					$http.get(path, {
						transformResponse : function(data) {
							// convert the data to JSON and provide
							// it to the success function below
							var x2js = new X2JS();
							var json = x2js.xml_str2json(data);
							return json;
						}
					}).success(function(data, status) {
						//console.log('Sucess');

						callback(data);
					})
				}
			}
} ]);

What I have tried:

I am new to AngularJs. Could anyone help to write a factory using http service in angularJS so that the factory returns me a business object instead of promise or assigning value to the scope variable on success. I researched so many articles in the web, but all are using either callback function or by returning promises from the http service. Requirement : Let's say XMLtoJsonService is my factory which converts xml to json from the local folder. factory should be return business object so that in my controller I should be able to use in following way //controller
var obj = XMLtoJsonService.MethodName();
(No promises or callback function should be used in controller)

All the logic to convert promise or callback functions can be used in factory
