Problème de lecture d'un fichier XML avec Java
Bonjour,
J'ai un petit probleme en Java, je n'arrive pas à afficher ce que je veux pour un fichier XML.
Le but étant d'avoir le temps de toutes les station à toutes les stations :
Départ STN10 : arrivée STN11 --- Temps : ...
Départ STN10 : Arrivée STN12 --- Temps : ...
etc//
Départ STN11 : Arrivée STN10 --- Temps : ...
Je travaille sur un fichier XML mais je n'arrive pas à afficher tous les élément internes d'une liste . voici mon fichier XML : http://dl.free.fr/mXmBGlPpN
Et voila mon programme :
