How do I parse XML String as Objects with states?

I have the followin code:

BufferedReader in = new BufferedReader(
                new InputStreamReader(con.getInputStream()));
        String inputLine;`enter code here`
        StringBuffer response = new StringBuffer();
        while((inputLine = in.readLine()) != null){
            response.append(inputLine);
        }
        in.close();
        System.out.println(response.toString());

Output:

I want to parse it to Objects with such states as Id, Amount and Points. I tried to use "DOM and a StringReader", but tags are empty so I failed.
