Question

I have the following PHP code. The code will send a SOAP request and get a SOAP response. I need to get the value between 2 tags. When I run it. I will get the following response from the server on Chrome.

Code

$headers = array(

    "Content-length: ".strlen($xml_post_string),

);

$url = 'https://onepay-services.uat.aws.emagin.eu/api/soap/payment';


$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_post_string); // the SOAP request
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

$response = curl_exec($ch);

echo ($response);

curl_close($ch);

$res = htmlentities(strval($response));

var_dump($res);

The response I get back at Chrome

Question

How do I get the value between <ns2:paymentTransactionId>TX00VMR1HN5GBF5S</ns2:paymentTransactionId>

Solution

$xml = simplexml_load_string(htmlspecialchars_decode($res));

$xml->registerXPathNamespace('ns2', 'http://www.allianz-assistance.com/emagin/services/PaymentService/1.0');

foreach ($xml->xpath('//ns2:paymentTransactionId') as $item)
{
    echo '<pre> The value is: ' . $item . '</pre>';
}

Managed to solve it. It requires htmlspecialchars_decode to handle <
