Hi, What is happening not correctly in your opinion. the use of the RefreshStrategy is correct. Are you seeing your features on the map? If not i think since you get you're data from a local xml file it can be a same origin policy problem. If you can see your features i think the refresh is working correctly but the same data is shown.
Hope this helps you a bit in finding the problem.
