Hey I have a problem with the closed Tags like <startFeed /> and <endFeed /> because they are causing an XML error.
If I use <startFeed> and <endFeed> the xml page at least shows but there is no Feed in it.
It just looks like this
<feed xmlns="http://www.w3.org/2005/Atom" xml:lang="de">
<id>
http://wiki/mediawiki/index.php?title=RSS&action=feed&feed=atom
</id>
<title>RSS - Feed</title>
<link rel="self" type="application/atom+xml" href="http://wiki/mediawiki/index.php?title=RSS&action=feed&feed=atom"/>
<link rel="alternate" type="text/html" href="http://wiki/mediawiki/index.php?title=RSS"/>
