Contao Summit 2026 in Leipzig 15th and 16th October

generateXmlFiles

The generateXmlFiles hook is triggered when the XML files are (re)generated e.g. by clicking “System » Maintenance » Recreate the XML files” in the back end. It has no parameters and does not expect a return value.

Example

// src/EventListener/GenerateXmlFilesListener.php
namespace App\EventListener;

use Contao\CoreBundle\DependencyInjection\Attribute\AsHook;

#[AsHook('generateXmlFiles')]
class GenerateXmlFilesListener
{
    public function __invoke(): void
    {
        // Do something …
    }
}
