Comment pourrais-je être en mesure d'obtenir les valeurs des <a> balises qui sont à l'intérieur des balises <li>?

Answer 1

Ce que vous pouvez faire si votre <content> est bien formé, est de le transformer en XML puis d'utiliser e4x pour demander les informations que vous vouliez.

Vous avez encore une chose à faire, c'est que votre XML contient namespace donc pour obtenir le noeud de contenu, vous devez en prendre soin. Je vous suggère de lire le bon post sur XML here par exemple.

Ainsi, le nœud content est à l'intérieur du nœud entry qui ont aussi un namespace, mais comme il est le même que le nœud racine, nous pouvons réutiliser la même namespace:

var xml:XML=<feed xmlns="http://www.w3.org/2005/Atom" version="1.0" xml:lang="en">
