Views2

The Views module in Drupal provides a Feed display that will allow for site owners to publish the content on their sites as RSS feeds. However, unlike a page or block display, the feed display does not allow for addition of custom tags inside the feed using the Views administration UI. There is however a way to add custom tags, attributes and values into the generated feed using hook_nodeapi.

Views is one of the most complex of all Drupal modules and one of the most useful of all Drupal modules. The only downside is that, since it is very complex, not too many people have been able to contribute to the documentation of the module. If you search Google for finding out how to programmatically set a filter in Views2 you probably wouldn't find any help. Here is how you do it.
