How to Retrieve the \'payment\' Element from a SOAP XML Response Using PHP?

Parsing SOAP XML

Issue: Retrieving 'payment' Element

Problem Overview:

PHP's simplexml_load_string() fails to parse a SOAP XML response and retrieve the 'payment' element.

Solution: Stripping Namespace Prefixes

One effective method to address this issue involves removing namespace prefixes from the XML response before using simplexml_load_string(). Here's how it's done:

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

Example: Parsing SOAP Response

For the provided SOAP XML response:

<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <PaymentNotification xmlns="http://apilistener.envoyservices.com">
      <payment>
        <uniqueReference>ESDEUR11039872</uniqueReference>
        <epacsReference>74348dc0-cbf0-df11-b725-001ec9e61285</epacsReference>
        <postingDate>2010-11-15T15:19:45</postingDate>
        <bankCurrency>EUR</bankCurrency>
        <bankAmount>1.00</bankAmount>
        <appliedCurrency>EUR</appliedCurrency>
        <appliedAmount>1.00</appliedAmount>
        <countryCode>ES</countryCode>
        <bankInformation>Sean Wood</bankInformation>
        <merchantReference>ESDEUR11039872</merchantReference>
      </payment>
    </PaymentNotification>
  </soap:Body>
</soap:Envelope>

Executing the code:

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

foreach ($xml->Body->PaymentNotification->payment as $item) {
    print_r($item);
}

This will output the 'payment' element as a SimpleXMLElement object, providing access to its child elements.
