Please help me:
I do not know where my mistake or what I adjust to my module to work.

the only thing I created is this:

<rss xmlns:g="http://base.google.com/ns/1.0" version="2.0">
<channel>
<title>
<! [CDATA [Auto Vyfuky.cz]]>
</ title>
<link> http://www.auto-vyfuky.cz </ link>
<description> cheapest stock exhausts </ description>
</ channel>
</ rss>

and the error message:
