ane mau custom bagian elemen <item></item> karena pada feed.xml yang muncul di website ane masih bagian halaman folder nya, rencananya mau di looping sekali lagi, source nya dari $page->url, apa bisa di Hook aja nih kang? atau edit di extension nya?

[taufik-nurrohman]

Bisa tapi melalui kait. Tidak ada cara khusus:

if ('feed.xml' === basename($url->path ?? "")) {
    Hook::set('content', function ($content) {
        $doc = new DOMDocument;
        $doc->loadXML($content);
        foreach ($doc->getElementsByTagName('item') as $v) {
            $link = $v->getElementsByTagName('link')->item(0).nodeValue;
            $new = $doc->createElement('asdf');
            // Append `<asdf></asdf>` to current `<item></item>`
            $v->appendChild($new);
        }
        return $doc->saveXML();
    }, 20);
}
