Magento – view entire system config – system.xml

In Magento modules, system.xml file is used to create admin configuration tabs and options.
Magento’s great feature allows developers to create advanced configurable modules in a little time. At the run time Magento collects all the xml files and group them into a single file.

To view the system.xml file simply paste this code snippet in any controllers and run it. A large xml will be open.

<?php
//header('Content-Type: text/plain');
header('Content-Type: text/xml');
echo $config = Mage::getConfig()
->loadModulesConfiguration('system.xml')
->getNode()
->asXML();
exit();
?>
