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 je l'ai appris est interrogé par le XPath.

Par exemple, comment pourrais-je interroger les données / SearchResults: searchresults / demande / adresse? 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 en blanc.

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 du 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();
