Je veux récupérer les 2 balise <yweather:forecast> ET LIRE leurs attributs. J'ai essayé via DOM ou parse_xml. J'accède facilement aux attributs des balises <img> ou <a> du document mais pas moyen d'accèder aux attributs des balises contenant des ":" comme <yweather:location> ou <yweather:forecast>.

Je fais mes test sur un serveur apache 2.* avec php5.

D'avance merci pour vos réponses et si possible exemple concret :-)

Cordialement,
Greg
