Feeds tagged, and a MySQL feed

I have made changes to the RSS Feed of this blog:

1. Each <item/> does now contain a container <tags/>, inside a sequence of <tag/> containers, with each posts tags.
2. There is now a second RSS feed for posts tagged #mysql, because of demand. You can find it at https://blog.koehntopp.info/feed_mysql.xml .

Example for the tags:

<channel>
	<title>Die wunderbare Welt von Isotopp</title>
	...
	<item>
		<title>A post title</title>
		<link>https://blog.koehntopp.info/2020/09/...</link>
		<guid isPermalink="false">/2020/09/...</guid>
		<tags><tag>lang_en</tag><tag>mysql</tag><tag>database</tag></tags>
		<description>blah blah blah</description>
	</item>
</channel>

So if you want only the MySQL content, subscribe to this feed , if you want all the content, subscribe to the original feed . In both cases, use the <tags/> to filter further down.
