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).

Simple way to get the URI of the default namespace:



<?php

    $document = new DOMDocument();

    $document->load($xml_file);

    $uri = $document->documentElement->lookupnamespaceURI(NULL);

?>
