Hello Gerardo,
Well i´ve been playing a bit with this piece of code you provided and have come to the limit of my xml vocabulary

I followed your tutorial and came to the follwing NL:
http://ws.geonames.org/rssToGeoRSS?type=kml&feedUrl=http%3A%2F%2Fwww.hidrografico.pt%2Frss-feed%2Fporto_rss.php%3Fcodp%3D74%26detail%3D
The result is the RSS feed of Tide hight predictions from
www.hidrografico.pt.The problem I am having is the following:
I don´t need geoRSS to placemark the RSS feeds because I know their locations already so firstly how do I dissable automátic positioning of the feeds in GE?
I looked in at
http://www.geonames.org/rss-to-georss-converter.html under the parameters table and found that the "geoRSS" param has the following applicable strings simple,gml,w3cGeo, but how do I apply this to my NL?
Do I insert the param and string directly onto the NL href location? or do I have to edit the NL in KML mode by hand and insert Lat and Long in code?
Help would be greatly apreciated!
Regards,
Djorge
