XML数据 - 如何访问

Question

我正在运行curl请求并返回以下内容：

Array
(
    [@attributes] => Array
        (
            [exp_cid] => 0BqO
        )

    [REQUEST] => Array
        (

                )

            [MB01] => Array

                (

                        (

                        )

                    [V5CDATAITEMS] => Array
                        (
                            [0] => Array
                                (
                                    [DATE] => 20090825
                                )

                            [1] => Array
                                (
                                    [DATE] => 20041007
                                )

                        )

                )

        )

)

我正在努力获取回报，我尝试了以下但是它没有返回任何内容：

foreach ($xml->REQUEST->MB01 as $requestData) {

echo $requestData;

}

我的另一个问题是取决于它将返回不同的MB块的车辆注册表，如果它们被返回则返回它们。

感谢。

修改

这是我正在运行的完整代码，当它运行时，我得到的只是＆lt;这有什么意义吗？

$ch = curl_init($URL);
curl_setopt($ch, CURLOPT_MUTE, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml'));
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);

echo $output[0]['REQUEST']['MB01']['DATEOFTRANSACTION'];

干杯。

Answer 1

返回是一个数组，而不是一个对象。试试这个：

foreach ($xml['REQUEST']['MB01'] as $requestData) {

    if(is_array($requestData) {
        print_r($requestData);
    } else {
        echo $requestData;
    }

}
