This is a small script that automatically creates an RSS feed of all surveys or by language. Just copy rss.php to the main directory of LimeSurvey.

Usage example:
http://www.yourdomain.com/rss.php
or for specific language:
http://www.yourdomain.com/rss.php?language=de

If you want to embed the results of RSS try this simple perl script:
