[fw-general] zend_feed_writer with own namespace

[Frank Habermann]

Hi,

i want to create an atom feed with some own tags in it.
So i read the doku on:
http://framework.zend.com/manual/en/zend.feed.modifying-feed.html

So i see example2 is good for me. I have an atom entry with own tags.

My problem is now: How could i create a complete feed with zend_feed?

I tried with:
$writer = new Zend_Feed_Writer_Feed();
$entry = new Zend_Feed_Entry_Atom();
$writer->addEntry($entry);

That bring me up an error:
"Catchable fatal error: Argument 1 passed to 
Zend_Feed_Writer_Feed::addEntry() must be an instance of 
Zend_Feed_Writer_Entry, instance of Zend_Feed_Entry_Atom given"

So, how could i create a complete atom feed with own tags?

regards,
Frank
