Parse données météorologiques de Weatherbug en PHP

Question

Salutations,

J'essaie d'analyser les données météorologiques en direct du flux RSS de Weatherbug en PHP. J'avais précédemment utilisé simplexml_load_string() avec les données météorologiques de la NOAA mais je n'arrive pas à comprendre comment sortir les données dont j'ai besoin de Weatherbug.

Voici le XML pour les conditions actuelles:

<rss version="2.0" xmlns:georss="http://www.georss.org/georss">
