Parsing a SOAP response with PHP in different ways

How to parse SOAP response without SoapClient

I have a simple nuSoap XML response:

<?xml version="1.0" encoding="utf-8"?>
<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>
        <LoginResult xmlns="http://Siddin.ServiceContracts/2006/09">FE99E5267950B241F96C96DC492ACAC542F67A55</LoginResult>
    </soap:Body>
</soap:Envelope>

Now I'm trying to parse it with simplexml_load_string as suggested here: parse an XML with SimpleXML which has multiple namespaces and here: Trouble Parsing SOAP response in PHP using simplexml, but I can't get it working.

This is my code:

$xml = simplexml_load_string( $this->getFullResponse() );
$xml->registerXPathNamespace('soap', 'http://schemas.xmlsoap.org/soap/envelope/');
$xml->registerXPathNamespace('xsi', 'http://www.w3.org/2001/XMLSchema-instance');
$xml->registerXPathNamespace('xsd', 'http://www.w3.org/2001/XMLSchema');

foreach($xml->xpath('//soap:Body') as $header) {
    var_export($header->xpath('//LoginResult')); 
}

But I still get only this in result:

/* array ( )

What am I doing wrong? Or what simple thing am I missing to understand?

The working end result with DOM by MySqlError:

$doc = new DOMDocument();
$doc->loadXML( $response  );
echo $doc->getElementsByTagName( "LoginResult" )->item(0)->nodeValue;

The working end result with SimpleXML by ndm:

$xml = simplexml_load_string( $response );
foreach($xml->xpath('//soap:Body') as $header) {
    echo (string)$header->LoginResult;
}

Answer 1

$doc = new DOMDocument();
$doc->loadXML( $yourxmlresponse );

$LoginResults = $doc->getElementsByTagName( "LoginResult" );
$LoginResult = $LoginResults->item(0)->nodeValue;

var_export( $LoginResult );
