How to parse SOAP XML?

One of the simplest ways to handle namespace prefixes is simply to strip them from the XML response before passing it through to simplexml such as below:

$your_xml_response="<Your XML here>";
$clean_xml = str_ireplace(['SOAP-ENV:', 'SOAP:'], '', $your_xml_response);
$xml = simplexml_load_string($clean_xml);

This would return the following:

SimpleXMLElement Object
(
    [Body] => SimpleXMLElement Object
        (
            [PaymentNotification] => SimpleXMLElement Object
                (
                    [payment] => SimpleXMLElement Object
                        (
                            [uniqueReference] => ESDEUR11039872
                            [epacsReference] => 74348dc0-cbf0-df11-b725-001ec9e61285

                            [bankAmount] => 1.00
                            [appliedCurrency] => EUR
                            [appliedAmount] => 1.00
                            [countryCode] => ES
                            [bankInformation] => Sean Wood
                            [merchantReference] => ESDEUR11039872
                        )

                )

        )
