Я анализирую KML с помощью SAX, и только первые 2 атрибута метки метки считываются правильно (имя и описание).Другие 2 (стиль, координаты) являются пустыми или нулевыми.Мой тестовый KML-файл выглядит так:

Мой класс синтаксического анализатора:

//Log.d("Velikost lista: ",Integer.toString(placemarks.size()));
Spremljaj.setList(placemarks);
}

}
@Override

Понятия не имею, что происходитнеправильно, потому что я делаю одно и то же для всех четырех атрибутов метки.
