Si vous ne pouvez pas dire déjà, il est la sortie standard de l'API Zillow. Je veux stocker les données d'informations stockées entre certaines balises, que j'ai appris est interrogé à travers le xpath.

Par exemple, comment rechercher les données dans/SearchResults: searchresults/request/address? Faire quelque chose comme ça ne fonctionne pas lorsque je fais écho/impression variable:

$xml = simplexml_load_file("-truncated XML URL-"); 
$result = $xml->xpath('/SearchResults:searchresults/request/address') 

D'après ce que je comprends, la variable $ result doit contenir la valeur trouvée imbriquée dans cette valeur% ICI%, correct? Mais il imprime "Array", et quand je print_r, il retourne vide.

Answer 1

Voici un moyen simple d'obtenir cette information:

<?php 
    $xml = simplexml_load_file("test.xml"); 
    echo $xml->request->address; 
?> 

Answer 2

Vous devez utiliser l'espace de nom complet et non le nom abrégé.

Answer 3

Utilisez http://simplepie.org

$xml = "yourxml code here"; 

$feed = new SimplePie(); 
$feed->set_raw_data($xml); 
$feed->init(); 
$feed->handle_content_type(); 
echo $feed->get_adress();
