Parse SOAP Response

[AeroProDrive]

Hi Guys,

I have this SOAP message to be parsed using SimpleXML:

<soap:envelope 
               xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" 
               xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
               xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <soap:body>
    <isokresponse xmlns="http://tempuri.org/">
      <isokresult>1</isokresult>
    </isokresponse>
  </soap:body>
</soap:envelope>

Then I load the XML:

$xml = simplexml_load_string($result);

I assume I need to register namespace e.g.

$xml->registerXPathNamespace("soap","http://schemas.xmlsoap.org/soap/envelope/");

But what's next? How do I get the value of the element isokresult?

Thank you so much

If all you want is the isokresult then you can get it... well, I won't say "easily" because SOAP just loves using namespaces, but it is a one-liner. Kinda. Don't need XPath.

(string)$xml
	->children("http://schemas.xmlsoap.org/soap/envelope/") // switch to soap namespace
	->body // <soap:body>
	->children("http://tempuri.org/") // switch to this isokwhatever namespace
	->isokresponse // <isokresponse>
	->isokresult // <isokresult> (still in the isok namespace)
