How to create an auto-generated rss feed on a site for Yandex news?

Question

RSS

Hello! Please tell me how to create an rss channel on the site, which would be updated periodically, for example, once every 7 days. This is necessary for Yandex news. Maybe there are special services or already written scripts for this?
Here I found a service for generating the feed itself , but how to make it so that now it is periodically updated?
Online now:

<link href="/ru/rss/" type="application/rss+xml" title="rss" rel="alternate"/>

<rss version="2.0">
<channel>
<title>
<![CDATA[
Название сайта
]]>
</title>
<link>ссылка</link>
<description>
<![CDATA[ Новости ]]>
</description>
<language>ru</language>
</channel>
</rss>

And in .htaccess
AddOutputFilterByType DEFLATE application/rss+xml
