Ayuda Php5 e interpretación xml El caso es que el script es compatible con php4 por que utiliza "simplexml.class" pero, yo se que desde php5 ya no es necesaria esa class por que php5 tiene soporte nativo para xml.
Entonces, me gustaria a ser posible si alguien podria introducir los cambios necesarios para que el script funcione sin necesidad de esta class. (no se programar php...)
Aqui esta el codigo:
