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.

What have you tried?
Anyway you can use PHP's simplexml_load_file or the full featured DOMDocument class
