I'm sure it wouldn't help.

And now I know what the real problem is.  I have downloaded an atom-file
you mentioned
<http://karl-voit.at/feeds/lazyblorg-all.atom_1.0.links-and-content.xml>
and it is a *malformed* xml file.  I manually called 'xsltproc' with
'atom2rss.xsl' on this xml-file and got the following output:

--8<---------------cut here---------------start------------->8---
$ xsltproc /path/to/atom2rss.xsl /home/alexx/downloads/lazyblorg-all.atom_1.0.links-and-content.xml > f1

So as you can see, there are 3 places in this file where instead of a
proper "&amp;" sequence, a simple "&" is used (which is incorrect).  If
these errors will be fixed, I almost sure your original code will work.

No need to do it, your initial code should work (for a proper atom file).
