如果您还不能确定，那就是 Zillow API 的标准输出。我想存储某些标签之间存储的信息的数据，我了解到是通过xpath查询的。

例如，如何查询 /SearchResults:searchresults/request/address 中的数据？当我回显/打印变量时，这样做不起作用：

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

据我了解，$result 变量应该包含嵌套在 %VALUE HERE% 中的值，对吗？但它打印“数组”，当我 print_r 时，它返回空白。

这是获取该信息的简单方法：

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

您需要使用完整的命名空间而不是短名称。

使用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();
