Opening an xml document in Android not working

I'm using an xml document on resources/raw in order to fill a ListView, here's the code:

List<Item> items = new ArrayList<Item>();
    try {
        BufferedReader br = new BufferedReader(new InputStreamReader(getResources().openRawResource(R.raw.data)));
        XmlPullParser p = XmlPullParserFactory.newInstance().newPullParser();
        p.setInput(br);
        int tipoevento = p.next();
        while (tipoevento != XmlPullParser.END_DOCUMENT) {
            switch (tipoevento) {
                case XmlPullParser.START_TAG:
                    items.add(
                            new Item(
                                    Integer.parseInt(p.getAttributeValue(null,"id")),
                                    p.getAttributeValue(null,"name"),
                                    p.getAttributeValue(null,"url")));
                    break;
                default:break;
            }
            tipoevento=p.next();
        }
        br.close();
    }
    catch(Exception e) {
        Log.e("Error: ", e.getMessage());}

And, when I run it, I get the following error: Error:﹕ Invalid int: "null".
And the listview is empty The xml document isn't empty, I did it, here it is:

<?xml version="1.0" encoding="utf-8"?>
<filmList>
<film name="Following" id="R.drawable.following" url="http://www.imdb.com/title/tt0154506/"/>

You need to check for a null value

if (p.getAttributeValue(null,"id") != null) {
    items.add(
      new Item(
            Integer.parseInt(p.getAttributeValue(null,"id")),
                   p.getAttributeValue(null,"name"),
                   p.getAttributeValue(null,"url")));
}
