Is there a way to filter the RSS feed generated to only process posts that contain certain keywords?


Not yet.

Isn’t it possible to use contains(.,‘yourtext’) in xpath request?


Hi Forger, yes, it’s possible to specify what to extract for each post, but I think what Manuel wants is a way to completely exclude feed items if they do not contain a certain string or pattern. I’m pretty sure even if you strip everything using XPath in the relevant site config file, the item’s title and other related fields will still be preserved in the generated feed.
