如何打印SimpleXmlElement对象的值

我从使用Guzzle的服务器获取SimpleXML对象。打印为字符串的响应看起来像有效的XML。但是当我尝试获取单个元素值时，我变得空白。如何打印SimpleXmlElement对象的值

请帮我看看是什么问题。

我的代码是在这里以及在Viper-7：

    $xml = '<?xml version="1.0" encoding="UTF-8"?>

您可能需要拼写在调用'simplexml_load_string'时输出命名空间。请参阅[这些文档]（http://www.php.net/manual/en/function.simplexml-load-string.php），尤其是'ns'和'is_prefix'参数。 – collapsar

@collapsar - 试过但无法做到。 http://viper-7.com/aOjiAA – Srihari

注：把你的代码放到你的问题，你会更容易让别人帮你。

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

你需要嵌套循环迭代。首先，您需要正确选择<OrdersList>节点，请参阅外部循环。

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

的<OrdersList>孩子们namespaced：
$order->OrderNumber不起作用，但children() - 方法做这项工作：

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

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

    } 

}

自开始以来，我已经在代码中提出了这个问题。只是xml非常庞大，代码仍然隐藏在底部。感谢您的帮助，并解决了问题 – Srihari

@Srihari哦对不起，我没有向下滚动。 – michi
