How to get values from below result using PHP.

<?xml version="1.0" encoding="UTF-8"?>

Your XML contains namespace-prefixed tags as it’s common for SOAP responses.

Have a look at following comment from php’s SimpleXML docs:

$xml = <<<XML
<?xml version="1.0" encoding="UTF-8"?>
<people xmlns:p="http://example.org/ns" xmlns:t="http://example.org/test">
    <p:person id="1">John Doe</p:person>
    <p:person id="2">Susie Q. Public</p:person>
</people>
XML;

$sxe = new SimpleXMLElement($xml);

$ns = $sxe->getNamespaces(true);

$child = $sxe->children($ns['p']);

foreach ($child->person as $out_ns)
{
    echo $out_ns;
}

In your case code accessing the properties should look like that (it’s tested against your XML in so.xml file):

<?php
  $xml = file_get_contents('so.xml');
  $sxe = simplexml_load_string($xml);

  $ns = $sxe->getNamespaces(true);

  $child =
    $sxe->children($ns['soapenv'])->
      Body->children($ns['p558'])->
      registerDonorResponse->registerDonorReturn->children($ns['p118']);

  var_dump($child);

Result:

$ php -f so.php 
object(SimpleXMLElement)#4 (3) {
  ["clientRegistrationId"]=>
  string(4) "clr1"
  ["labcorpRegistrationNumber"]=>
  string(9) "100059064"
  ["registrationTime"]=>
  string(24) "2012-12-01T05:40:51.628Z"
}

Please note however that issuing SOAP requests and parsing responses by hand is generally a bad practice, consider using SOAP client for that.
