XML not parse with soap-env having custom tags in PHP

[mohib_ayubi]

Dear Experts,

I need your help in the following:

I am experiencing an error while parsing my XML response in PHP

I have a below XML response, when i call from CURL request

<soap-env:Header>
    <eb:MessageHeader xmlns:eb="http://www.ebxml.org/namespaces/messageHeader" eb:version="1.0" soap-env:mustUnderstand="1">

        </eb:To>
        <eb:ConversationId>2021.01.DevStudio</eb:ConversationId>

</soap-env:Body> </soap-env:Envelope>

To parse the above XML i have initially tried with the simplexml_load_String but it gives an empty response.

Then i tried DOM method by using following code, here considering $response->Data is the above XML.

   $dom = new DOMDocument;
    $dom->preserveWhiteSpace = false;
    $dom->loadXML($response->Data);
    $dom->formatOutput = true;      
    $XMLContent = $dom->saveXML();

It gives me following output again:

<!--?xml version="1.0" encoding="UTF-8"?-->
<soap-env:envelope xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/">   <soap-env:header>
    <eb:messageheader xmlns:eb="http://www.ebxml.org/namespaces/messageHeader" eb:version="1.0" soap-env:mustunderstand="1">

        <eb:partyid eb:type="URI">Sabre_API</eb:partyid>
      </eb:from>
      <eb:to>
        <eb:partyid eb:type="URI">Agency</eb:partyid>
      </eb:to>
      <eb:conversationid>2021.01.DevStudio</eb:conversationid>

So i plan to get data from NODE like below

$XMLContent->getElementsByTagName('soap-env:header')->item(0)->nodeValue);

But instead of giving me a node values it start giving me and error.
I just want to get the data in the node wsse:binarysecuritytoken

Did anyone experience some thing like this?

Can you please help me in that??

Tried also following, but got not helpful still

$domDocument = new DOMDocument();
$domDocument->loadXML($XMLContent);
$carriers=array();
$results=$domDocument->getElementsByTagName("wsse:Security");
foreach($results as $result)
{
    foreach($result->childNodes as $node)
    {
        if($node instanceof DOMElement)
        {
            array_push($carriers, $node->textContent);
        }
    }

}
var_dump($carriers);

Tried following way i used to do also, but it also wont work.

		$dom = new DOMDocument;
		$dom->preserveWhiteSpace = false;
		$dom->loadXML($response->Data);
		$dom->formatOutput = true;		
		$XMLContent = $dom->saveXML();

		$xml = simplexml_load_String($XMLContent, null, null, 'soap-env', true);	

			if(!$xml)
				trigger_error("Encoding Error!", E_USER_ERROR);
			
			$Results = $xml->children('SOAP',true);
				
			foreach($Results->children('SOAP',true) as $fault){
				if(strcmp($fault->getName(),'Fault') == 0){
					trigger_error("Error occurred request/response processing!", E_USER_ERROR);
				}
			}
			
			foreach($Results->children('soap-env',true) as $nodes){
				var_dump($nodes->getName());	
			}

Ok finally after spent hours, i got that! I had to modify according to tag names as below, in the most parent i had to used soap-env instead of SOAP.

        $dom = new DOMDocument;
        $dom->preserveWhiteSpace = false;
        $dom->loadXML($response->Data);
        $dom->formatOutput = true;      
        $XMLContent = $dom->saveXML();

        $xml = simplexml_load_String($XMLContent, null, null, 'soap-env', true);    

        if(!$xml)
            trigger_error("Encoding Error!", E_USER_ERROR);
        
        $Results = $xml->children('soap-env',true);
            
        foreach($Results->children('soap-env',true) as $fault){
            if(strcmp($fault->getName(),'Fault') == 0){
                trigger_error("Error occurred request/response processing!", E_USER_ERROR);
            }
        }

        foreach($Results->children('wsse',true) as $nodes){         
            if(strcmp($nodes->getName(),'Security') == 0){
                foreach($nodes->children('wsse',true) as $securityNodes){
                    if(strcmp($securityNodes->getName(),'BinarySecurityToken') == 0){                           
                        $tokenParsed = (string)$securityNodes;                                                      
                    }
                }
            }           
        }

XPath is also an option; for I don't know what reason, it's necessary to register any namespaces that are used in the query.

$dom = new DOMDocument;
$dom->loadXML($response->Data);

$xpath = new DOMXPath($dom);
$xpath->registerNamespace('wsse','http://schemas.xmlsoap.org/ws/2002/12/secext');

$token = $xpath->evaluate('//wsse:Security/wsse:BinarySecurityToken')->item(0)->textContent;

var_dump($token);

You could also get the element directly by tag name if you again take the namespace into account:

$domDocument->getElementsByTagNameNS("http://schemas.xmlsoap.org/ws/2002/12/secext", "Security");
