After all these years with RSS feeds and PHP I believed there had to be some ready made modules for RSS feed generation. It turns out none of them supports GeoRSS and most of them handle XML character encoding totally wrong. Really strange!

After some research I found a somewhat easy to use and expand RSS module PHP Universal Feed Generator. It didn’t support the Atom rights tag and of course no GeoRSS tags. But it is quite easily extensible. Now I got a working Atom+GeoRSS and KML export.

I’ll try to submit my changes to the original author. We’ll see if he’s interested.
