Cannot parse Curl Response from Soap Service (Post petition) - php

Question

im trying to parse a curl response for this request:
$soapUrl = "https://soap_example_url.com/log_in";
// xml post structure
$xml_post_string = '
<soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:urn="urn:debisys-soap-services">
<soapenv:Body>
<urn:Login soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<version xsi:type="xsd:string">'.$version.'</version>
<userName xsi:type="xsd:string">'.$userName.'</userName>
<password xsi:type="xsd:string">'.$password.'</password>
<languageOption xsi:type="xsd:string">'.$language.'</languageOption>
</urn:Login>
</soapenv:Body>
</soapenv:Envelope>
';
$headers = array(
"Content-type: text/xml;charset=\"utf-8\"",
"Accept: text/xml",
"Cache-Control: no-cache",
"Pragma: no-cache",
"Content-length: ".strlen($xml_post_string),
); //SOAPAction: your op URL
$url = $soapUrl;
// PHP cURL for https connection with auth
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_post_string); // the SOAP request
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
// converting
$response = curl_exec($ch);
curl_close($ch);
// converting
$response1 = str_replace("<soap:Body>","",$response);
$response2 = str_replace("</soap:Body>","",$response1);
But when i try to parse "$response2" i get nothing:
$xml = simplexml_load_string($response2);
$json = json_decode(json_encode($xml));
echo json_encode($xml, JSON_PRETTY_PRINT);
Here's what i get:
SimpleXMLElement Object ( )
{}
print_r: stdClass Object ( )
When i use print_r ($response2); function i get this in my browser:
<Login2Response><Version>01</Version><SiteID>xxxx</SiteID><ClerkId>xxxxx</ClerkId><ResponseCode>00</ResponseCode><ResponseMessage>user logged in</ResponseMessage></Login2Response>
And when i use "json_encode" i get this:
"\n \n \n <LoginResponse><Version>01<\/Version><SiteID>xxxxx<\/SiteID><ClerkId>xxxxx<\/ClerkId><ResponseCode>00<\/ResponseCode><ResponseMessage>user logged in<\/ResponseMessage><\/LoginResponse><\/return>\n <\/ns1:Login2Response>\n <\/soapenv:Body>\n<\/soapenv:Envelope>\n"
So i tried copy/paste the xml from my browser to a variable like this:
$returned_xml = '<LoginResponse><Version>01</Version><SiteID>xxxxx</SiteID><ClerkId>xxxxx</ClerkId><ResponseCode>00</ResponseCode><ResponseMessage>user logged in</ResponseMessage></LoginResponse>';
And it works, but i need to use $response2 to make it dynamically, thanks in advance.

Answer 1

I'm closer i did this:
$response2 = preg_replace('/(<\/?)(\w+):([^>]*>)/', '$1$2$3', $response2);
$xml = simplexml_load_string($response2);
$xml = var_dump($xml);
echo '<br><br>';
print_r($xml);
And now i'm getting this response:
object(SimpleXMLElement)#1 (1) { ["soapenvBody"]=> object(SimpleXMLElement)#2 (1) { ["ns1Login2Response"]=> object(SimpleXMLElement)#3 (1) { ["return"]=> string(194) "018821909123400USER LOGGED IN SUCCESSFULLY" } } }
How can i access to only the ["return"] response to parse it as json object?
