Question

I need to loop through the items as an array within the SimpleXMLElement Object below but cannot seem to access it using $order->order->order->items. I can access the delivery and billing addresses using the same format, ie. $order->order->order->delivery_address and expected to get to the items array in the same way. However, I get an empty SimpleXMLElement Object when I print_r($order->order->order->items)

Answer 1

Using Dan Lees suggestion I tried SimpleXMLElement::children() and did the below which works

foreach ($order->children() as $order) {
        foreach ($order->children() as $order_details) {
            foreach ($order_details->children() as $order_items) {
                echo $order_items->id;
            }
        }
    }
