Try this:

 ?>

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;
    }
}

Answer 3

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";
}
