如何打印SimpleXmlElement对象的值

Question

I am getting a SimpleXML object back from a server using Guzzle. The response printed as string looks like valid XML. But when I try to get the individual element values, I am getting blank.

Please help me find what the problem is.

My code is here as well as on Viper-7:

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

Note: By putting your code into your question, you will make it easier for others to help you.

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

You will need 2 nested loops to iterate. First, you will want to select the <OrdersList>-nodes correctly, see the outer loop.

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

The children of <OrdersList> are namespaced:
$order->OrderNumber doesn't work, but the children()-method does the job:

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

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

    }

}
