Comment analyser SOAP XML ?

Question

XML SOAP :

 <?xml version="1.0" encoding="utf-8"?>
<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>

Comment obtenir l'élément « paiement » ?

J'essaye d'analyser (PHP)

 $xml = simplexml_load_string($soap_response);
$xml->registerXPathNamespace('soap', 'http://schemas.xmlsoap.org/soap/envelope/');
foreach ($xml->xpath('//payment') as $item)
{
    print_r($item);
}

Le résultat est vide :( Des idées comment l'analyser correctement?

Answer 1

L'un des moyens les plus simples de gérer les préfixes d'espace de noms consiste simplement à les supprimer de la réponse XML avant de la transmettre à simplexml, comme ci-dessous :

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

Cela renverrait ce qui suit :

 SimpleXMLElement Object
(
    [Body] => SimpleXMLElement Object
        (
            [PaymentNotification] => SimpleXMLElement Object
                (
                    [payment] => SimpleXMLElement Object
                        (
                            [uniqueReference] => ESDEUR11039872
                            [epacsReference] => 74348dc0-cbf0-df11-b725-001ec9e61285
                            [postingDate] => 2010-11-15T15:19:45
                            [bankCurrency] => EUR
                            [bankAmount] => 1.00
                            [appliedCurrency] => EUR
                            [appliedAmount] => 1.00
                            [countryCode] => ES
                            [bankInformation] => Sean Wood
                            [merchantReference] => ESDEUR11039872
                        )

                )

        )

)

La version PHP > 5.0 a un joli SoapClient intégré. Ce qui ne nécessite pas d'analyser la réponse XML. Voici un exemple rapide

 $client = new SoapClient("http://path.to/wsdl?WSDL");
$res = $client->SoapFunction(array('param1'=>'value','param2'=>'value'));
echo $res->PaymentNotification->payment;

$xml = '<?xml version="1.0" encoding="utf-8"?>
                <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>';
        $doc = new DOMDocument();
        $doc->loadXML($xml);
        echo $doc->getElementsByTagName('postingDate')->item(0)->nodeValue;
        die;

Le résultat est :

Tout d'abord, nous devons filtrer le XML afin de l'analyser dans un objet

 $response = strtr($xml_string, ['</soap:' => '</', '<soap:' => '<']);
$output = json_decode(json_encode(simplexml_load_string($response)));
var_dump($output->Body->PaymentNotification->payment);
