Reade data from a server API and show in browser. javascrip, xml, soap

I have built a project in Visual Studio MVC and I want to retrieve some data from a URL and put it on my browser. I want to retrieve data from a local server that is built to send data as XML and SOAP using the POST method. The calls that I do is with javascript / Jqurey.

I've been testing several different ways, but without Likas retrieve data from the API. In The APIs are a number of subject is eg GETMACHINS and into GETMACHINS list are such stop, service, alarm, and production. I want to pick these values and show in my browser.

I am new when it comes to retrieve data from URL / server.

I am grateful if someone can help me!

 $.get('http://localhost/api_.asmx', function (data) {
       //test data till huvud rubriken
       var output;
       output += '<li>' + data.Stop + '</li>';
       output += '<li>' + data.service + '</li>';
       output += '<li>' + data.alarm + '</li>';
       alert(data);
       $('#update_rubrik').html(output);
});
