Simple way to get the URI of the default namespace:

<?php
    $document
= new DOMDocument();
   
$document->load($xml_file);
   
$uri = $document->documentElement->lookupnamespaceURI(NULL);
?>

You have to pass *null* to lookupNamespaceURI if you want to read the default namespace. Passing an empty string doesn't work - even though the documentation says that lookupNamespaceURI takes a string as argument (and null would just be converted to an empty string).
