Let's say you're getting the following response from an API call:

```
[OrderArray] => SimpleXMLElement Object
    (
        [Order] => Array
            (
                [0] => SimpleXMLElement Object
                    (
                        [OrderID] => etc...etc..<br>

```

How do I go about converting this back into well-formatted XML so that I can save each of my order arrays into their own separate file? (Please don't ask me why I have to perform this seemingly futile task.)
