Question

我使用Guzzle从服务器获取SimpleXML对象。以字符串形式打印的响应看起来像有效的XML。但是当我试图获得单个元素值时，我变得空白。

请帮我找出问题所在。

我的代码就在这里以及Viper-7：

$sXml = simplexml_load_string ($xml);

foreach($sXml as $order){

    print_r($order);
    echo "<br/>";

注意：通过将您的代码放入您的问题中，您可以更轻松地让其他人帮助您。

$xml = simplexml_load_string($x); // assume XML in $x

您需要 2 嵌套循环才能进行迭代。首先，您需要正确选择<OrdersList> - 节点，请参阅外部循环。

foreach ($xml->OrdersList as $orders) {

<OrdersList>的孩子是namespaced：
$order->OrderNumber不起作用，但children() - 方法可以完成工作：

    foreach ($orders->children("typ", TRUE) as $name => $value) {

        echo "$name: $value <br />";

    }

}
