How to read nested elements in xml with dom parser or whatever

I want to read nested elements and assign all elements and dates to two dimensional array. In the following xml example, the elements are <M-1>,<M-11>,<M-111>,<M-2>,<M-22>,<M-3> and the dates are m111,m22,m3. I want to 2D array like that is String array[][] = {{"M-1","M-11","M-111","m111"},{"M-2","M-22","m22"},{"M-3","m3"}}; Thanks.
