从SimpleXML对象中检索一个值

不好意思问这样一个“noob”问题，但我一直在试图找到一个简单的例子，说明如何在过去的几个小时中循环返回的xml，并且我没有哪里。我只是希望能够循环访问xml并为每个订单提取'Amount'属性和'AmazonOrderId'属性。我不知道如何循环，也不知道如何获取相关数据。从SimpleXML对象中检索一个值

您知道如何使用SimpleXML，但不知道如何循环？这只是没有意义。我会给你一个提示。您可以在'$ object-> ListOrdersResult-> Orders-> Order'中访问您感兴趣的数组，其中'$ object'是您执行var_dump的主要SimpleXML对象。 – 2013-03-14 00:34:35

而不是'print_r'使用'$ xml-> asXML（'php：// stdout'）;'，美化输出，然后你通常会看到如何访问元素。如果你还不确定，有很多类似的问题已经回答。 – hakre 2013-03-14 00:51:14

SimpleXML很棒，不是吗？

foreach ($xml->ListOrdersResult->Orders->Order as $order) { 
    $amazonOrderId = (string) $order->AmazonOrderId; 
    $orderTotal = (string) $order->OrderTotal->Amount; 
}

我用(string)型铸造，因为你会得到SimpleXMLElement S表示这些标值返回，否则。

为每个订单提取'金额'属性和'AmazonOrderId'属性。

如果我把你字的字，那么这就是你要找的内容：

$allThoseAttributes = $xml->xpath('//Order/@Amount|//Order/@AmazonOrderId');

然而，更多的可能是你正在寻找：

$orders = []; 
foreach ($xml->xpath('//Order') as $order) { 
    $orders[] = [ 
     'amazon' => (string) $order->AmazonOrderId 
     'total' => (string) $order->OrderTotal->Amount; 
    ]; 
}

因为你所称的属性是事实上的元素。如果您想了解有关XML和Xpath的更多信息，请阅读以下内容：XPath
