Aide pour affichage flux xml
Bonjour,
Bon je sais que c'est pas le moment mais je galère avec les flux rss 
je tente désesperement d'afficher un flux xml sur sur un serveur php<5.
J'ai tenté Magpapierss et d'autres sans succès...
j'ai enfin trouvé un truc pas mal le problème c'est que ça m'affiche un array avec plein de données dont je n'arrive pas à me débarasser, je souhaite juste conserver la liste des 10 dernières news.
Si quelqu'un qui maîtrise php a le temps de jeter un coup d'oeil...
Voici le fichier class rss200.php
Code:
<?php
class RSS {
// parser
