You should register the job namespace, then you can use the registered namespace-prefix in an XPath to select what you want:
$sxe = new SimpleXMLElement($xml);
$sxe->registerXPathNamespace('job', 'http://example.org/you-did-not-provide-the-job-namespaceURI-in-your-example');
$result = $sxe->xpath('//entry/job:location/job:region');
foreach ($result as $location) {
echo $location . "\n";
}

Answer 3

I would do it dynamically.
$xml = #simplexml_load_string($path) // loads your valid xml data
foreach($xml->channel->item as $entry) {
$namespaces = $entry->getNameSpaces(true);
foreach($namespaces as $ns=>$value)
{
$job = $entry->children($namespaces[$ns]);
$author = (string)$job->creator;
if ($author != "")
{
$someVariable = (string) $dc->creator;
}
}
