Convert specific XML to PHP Array

Question

I'm trying to convert this specific XML file to PHP Array

http://www.crcind.com/csp/samples/SOAP.Demo.cls?soap_method=QueryByName&name=John

The part I want to get is

<QueryByName diffgr:id="QueryByName1"msdata:rowOrder="0"><ID>174</ID><Name>Johnson,Brian T.</Name><DOB>1934-11-09</DOB><SSN>751-82-3888</SSN></QueryByName>  

I tried to use soapResponseToJson(xml) And

    $xmlfile = file_get_contents($path);

//convert xml string into an object
$xml = simplexml_load_string($xmlfile);

//convert into json
$json  = json_encode($xml);

//convert into associative array
$xmlArr = json_decode($json, true);

But keeps not working.

Can you help me please?
Kind regards.
