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

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

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

<?xml version="1.0" encoding="UTF-8"?> <soap-env:Envelope xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/">

    </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">

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??

UPDATE
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);

    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;                                                      
                        }
                    }
                }           
            }

    This is SOAP, an object serialization format that uses XML syntax. Best solution is to use a SOAP library. PHP has ext/soap for this. Using an XML library would be a level lower.

    The XML uses namespaces. Namespaces are specified using unique URIs. For readability/maintainability XML defines aliases for the URIs and uses them as prefixes for node names. However the following 3 examples all should be read as {http://schemas.xmlsoap.org/soap/envelope/}Envelope:

    • <soap-env:envelope xmlns::soap-env="http://schemas.xmlsoap.org/soap/Envelope/"/>
    • <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"/>
    • <Envelope xmlns="http://schemas.xmlsoap.org/soap/envelope/"/>

    Namespaces can be defined on any element node, so they can change even in a single document. That means that your code should not depend on the aliases/prefixes in the document, but the namespace URIs.

    I strongly suggest defining an array variable/constant for the used namespaces. Then you can use Xpath and the namespace aware DOM methods (with the suffix NS).

    // used namespaces, the keys do NOT need to match the prefixes in the XML.
$xmlns = [
    'soap' => 'http://schemas.xmlsoap.org/soap/envelope/',
    'eb' => 'http://www.ebxml.org/namespaces/messageHeader',
    'sec' => 'http://schemas.xmlsoap.org/ws/2002/12/secext'
];

$document = new DOMDocument();
$document->loadXML(getSoapXmlString());
$xpath = new DOMXpath($document);
// register your aliases for the namespaces
foreach ($xmlns as $alias => $uri) {
    $xpath->registerNamespace($alias, $uri);
}

$token = $xpath->evaluate(
  'string(//sec:Security/sec:BinarySecurityToken)'
); 

var_dump($token);

    DOMXpath::evaluate() allows for Xpath expression that return node lists and scalar values. If you cast a node list (specified by a location path) to string it will return the text content of the first node or an empty string.
