I am working on Hippo CMS, which has a plug-in for RSS feed
the RSS can grab documents from existed folders.
But I would like to implement a feature to let it grab document from facet but not real folder.
So I can do something like news/2012/published
to get what I want.
Anyone tried this before? Please share some idea about how I can do it.
Yes that should be possible. You could create a hippo:facetnavigation structure and show the tree like that. Next to that you probably need to modify the default RSSFeedBuilder component, so that it can handle this kind of structure.
