Dans mon application, j'analyse des données telles que «title», «link», «pubDate» et «description» à partir d'un fichier XML d'un flux RSS Wordpress. Dans la description du flux RSS, il y a le lien vers l'image sélectionnée, suivi de la description. Je voudrais mettre seulement la description dans le champ de texte, suivi par l'image dans une vue d'image. Le seul problème est, devrais-je implémenter un analyseur HTML à l'intérieur de mon NSXMLParser déjà existant, ou existe-t-il un moyen plus simple? Cela peut-il être fait dans le NSXMLParser lui-même?Analyse de la description d'un flux RSS
