Question

$xmlStr = <<<xml
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soap:Body>
        <client_insetResponse xmlns="http://120.26.103.193:2017/webservices/">
            <client_insetResult>0|</client_insetResult>
        </client_insetResponse>
    </soap:Body>
</soap:Envelope>
xml;
$xmlObj = simplexml_load_string($xmlStr);
var_dump($xmlObj);

The above code prints an empty object, indicating that the parsing failed

Answer 1

cannot be recognizedxmlns:soap,xmlns:xsi,xmlns:xsd.

You can process xmlns:soap改为xmlns-soap again.

Answer 2

The soap namespace is not recognized, refer to the following code:

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <soap:Body>
        <client_insetResponse xmlns="http://127.0.0.1/webservices/">
            <client_insetResult>0|</client_insetResult>
        </client_insetResponse>
    </soap:Body>
</soap:Envelope>
xml;
    
$xmlObj = simplexml_load_string($xmlStr);
$xmlObj->registerXPathNamespace('soap', 'http://schemas.xmlsoap.org/soap/envelope/');
$result = $xmlObj->xpath("soap:Body");

print_r($result);
