How to add virtual pages in sitemap.xml

Tested on 8.5.4

Generate Sitemap job will generate sitemap.xml with all pages in your sitemap.

You can add additional urls in the sitemap.xml by adding a custom listner to the on_sitemap_xml_ready event.

Express entry detail pages won't included in the sitemap.xml, but you can fix it with this event hook.

Please try to add this example code in your application/bootstrap/app.php.

<?php
/* @var Concrete\Core\Application\Application $app */
/* @var Concrete\Core\Console\Application $console only set in CLI environment */

/** @var \Symfony\Component\EventDispatcher\EventDispatcherInterface $director */
$director = $app->make(\Symfony\Component\EventDispatcher\EventDispatcherInterface::class);
$director->addListener('on_sitemap_xml_ready', static function ($event) use ($app) {
    /** @var \Concrete\Core\Page\Sitemap\Event\XmlReadyEvent $event */
    $xml = $event->getDocument();

    $entity = Express::getObjectByHandle('test');
    if (is_object($entity)) {
        $resolver = $app->make(\Concrete\Core\Url\Resolver\Manager\ResolverManagerInterface::class);
        $list = new \Concrete\Core\Express\EntryList($entity);
        $entries = $list->getResults();
        /** @var \Concrete\Core\Entity\Express\Entry $entry */
        foreach ($entries as $entry) {
            $id = $entry->getID();
            $lastMod = $entry->getDateModified()->format(DateTime::ATOM);
            $url = $xml->addChild('url');
            $url->addChild('loc', $resolver->resolve(['/express/detail/', 'view_express_entity', $id]));
            $url->addChild('lastmod', $lastMod);
            $url->addChild('priority', 0.5);
            $url->addChild('changefreq', 'weekly');
        }
    }

    $event->setDocument($xml);
});
