Parsing a SOAP response with PHP in different ways [duplicate]

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; }

i would suggest PHP DOMDocument php.net/manual/en/class.domdocument.php — MySqlError

$doc = new DOMDocument(); $doc->loadXML( $yourxmlresponse ); $LoginResults = $doc->getElementsByTagName( "LoginResult" ); $LoginResult = $LoginResults->item(0)->nodeValue; var_export( $LoginResult );

if you change var_export to echo it will return without ' mark var_export is just showing you that it's string

What's going wrong here is SimpleXMLs poor default namespace support. In order to fetch that node using an XPath expression, you'd need to register a prefix for the default namespace and use it in the query, even though the element isn't prefixed, for example:

foreach($xml->xpath('//soap:Body') as $header) { $header->registerXPathNamespace('default', 'http://Siddin.ServiceContracts/2006/09'); var_export($header->xpath('//default:LoginResult')); }

However, actually there's no need to use XPath for accessing this node, you can simply access it directly:

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

This seems to work in some way, but gives me string like this, witch is still not exactly what I need: SimpleXMLElement::__set_state(array( 0 => 'FE99E5267950B241F96C96DC492ACAC542F67A55', ))
Well, I've adapted your example code, ofcourse that's how a var_export of a SimpleXML node looks like, if you need to access the value, simply cast the node to a string: (string)$header->LoginResult
