I've added several articles about Groovy now. I really think that Groovy has a great future as I think I have said before.
Anyway one of the things that really impressed me when I started out with groovy was the XML support. After years of Digester, DOM, SAX etc it seemed almost too easy to be true. Anyway, I've added an aritcle that includes an example of how to create an ATOM feed. This was done based on the code I used to build the feed for this site.
