How can I read this file with php? I tried to read it SimpleXMLElement but it does not read file and give empty object

Answer 1

How did you try to read the xml? Did you may forgot to register your xpath Namespace?

Here is an example, being $yourSoapResponse the string response of your request:

$xml = new SimpleXMLElement($yourSoapResponse); 
$xml->registerXPathNamespace("soap", "http://schemas.xmlsoap.org/soap/envelope/");
$body = $xml->xpath("//soap:Body");
print_r($body);
