Both notes below are very useful, thank you both!
But it's not apparent what to do to access a specific value. Here's an slightly different
example:
<?php
$xml_doc = <<<XML
<?xml version='1.0'?>
<!-- without namespace: -->
<!-- <document> -->
<!-- with default namespace: -->
<manifest xmlns="uri:some_namespace">
<metadata>
<schemaversion>SCORM 1.2</schemaversion>
</metadata>
</manifest>
XML;
$xml = simplexml_load_string($xml_doc);
$namespaces = $xml->getNamespaces(true);
// register a prefix for that default namespace:
$xml->registerXPathNamespace("default", $namespaces[""]);
// and use that prefix in all of your xpath expressions:
$xpath_to_schemaversion = "//default:manifest/default:metadata/default:schemaversion";
var_dump($xml->xpath($xpath_to_schemaversion));
