我想从这个 XML 文件中提取：“ENTRY_URL where TITLE = Episodul 1: Pilot”

<?xml version="1.0"?>
<methodResponse>
    <params>
        <param>
            <value>
                <array>
                    <data>
                        <value>
                            <struct>

    </params>

我尝试了在互联网上找到的代码

$xml = simplexml_load_string($catapi);
$results = $xml->xpath('//methodResponse/params/param/array/data/value/struct/member/name[. = "TITLE"];

但它没有逻辑：| 这是一个活生生的例子：http ://www.ufilme.ro/api/load/under_the_dome_online/sezonul_1/674?apikey=raxeIJAb5ZnwoGn3

您拥有的 XML 不仅是 XML，它实际上是一个 XML-RPC 响应，您可以使用命名的相应 PHP 函数进行解码，xmlrpc_decode然后访问该元素：

$filter = function($key, $value) {
    return function(array $entry) use ($key, $value) {
        return isset($entry[$key]) && $entry[$key] === $value;
    };
};

$titleFilter = $filter('TITLE', 'Episodul 1: Pilot');
$array       = xmlrpc_decode(file_get_contents($url), 'utf-8');
$result      = array_filter($array, $titleFilter);

echo array_values($result)[0]['ENTRY_URL']; // prints "http://www.ufilme.ro/load/under_the_dome_online/sezonul_1/episodul_2_the_fire/674-1-0-5465"
