Unable to read XML from API call

Question

I have the following code to read xml data from 3rd party

$supplier_response = getsupplierresponse($argument1);
$resultxml = simplexml_load_string($supplier_response);
$test = getXMLNode($resultxml, "FormattedName");
var_dump($test); //no result

function getXMLNode($xmlobj, $path, $nodenumber=0){
  return $xmlobj->getElementsByTagName($path)->item(0)->childNodes->item($nodenumber)->nodeValue;
}

If I read the same xml from a local file, the code works and [var_dump($test);] gives proper result. Is there anything specifically done if we retrieve XML from a third party service in order to read the data?

Here is the xml I retrieved calling a 3rd party service.

Answer 1

The only way I could fix is this is to save locally and read it again. I am not sure if this is a perfect answer but something worked for me. The xml is made readable by calling the below function.

function cleanse_supplier_response($supplier_response){
    $result = simplexml_load_string($supplier_response);
    $xml_string = $result->saveXML();
    $thisxml_object = new DOMDocument();
    $thisxml_object->loadXML($xml_string);
    return $thisxml_object;
}

Hope this helps those who are curious about an option to fix the issue.
