domRSS
Création et parsing de fichier RSS avec l' extension DOM XML.
La classe DOM RSS étend la classe RSS 0.91 en offrant la possibilité de Parser / Créer vos documents RSS grace à l' extension DOM XML de PHP . La documentation est reduite au maximum, en effet l' utilisation est EXACTEMENT la même que pour la classe RSS. Reportez vous donc à la documentation de la classe RSS. Attention cependant l' extension DOM XML est experimentale et son implementation change très rapidement !
