I may be late for the party, it's actually very simple. Although there may be better ways of doing this. duration is in milliseconds.

public long getDuration() {
    String time = "PT15H12M46S".substring(2);
    long duration = 0L;
    Object[][] indexs = new Object[][]{{"H", 3600}, {"M", 60}, {"S", 1}};
    for(int i = 0; i < indexs.length; i++) {
        int index = time.indexOf((String) indexs[i][0]);
        if(index != -1) {
            String value = time.substring(0, index);
            duration += Integer.parseInt(value) * (int) indexs[i][1] * 1000;
            time = time.substring(value.length() + 1);
        }
    }
    return duration;
}
