Parser un flux XML en PHP pour récupérer une valeur

milkiway · 10 Février 2011

Bonjour,

J'ai un flux XML que je veux parser en PHP. J'utilise simplexml_load_file.

Code:

<?xml version="1.0" encoding="UTF-8"?>
<catalogue id="1">
 <progname>Panzani</progname>
 <store>
  <name>Panzani Pasta</name>
  <products>
   <product>
    <storeData>
     <data type="modele">Farfale</data>
     <data type="prix_catalogue">3.35</data>
    </storeData>
  </product>
  </products>
 </store>
</catalogue>

J'arrive sans souci à récupérer la valeur de "progname" (Panzani ici), store->name mais je ne vois pas du tout comment récupérer la donnée Farfale par exemple.
J'ai testé par store->products->product->storeData->data['modele'] mais ça ne marche pas. Pourquoi ? Comment faire ?

Un grand merci

Merci beaucoup, en fait par ce biais là j'y arrivais bien mais ce n'est pas très sur dans le sens où je en suis pas certain que 0 soit bien pour modèle (il suffit qu'il change de place).
J'ai donc fait autrement :
foreach($flux->store->products->product as $product){
foreach ($product->storeData->data as $node) {
$data[(string) $node['type']] = (string) $node;
}
Fourni sur un autre forum.
