Question

Is it possible to create multiple RSS feeds within one TWiki web by creating multiple topics based on WebRss topic with modified searches?

I am thinking of creating more targeted RSS feeds that list updates of only certain sets of topics within a web, not the entire web.

I haven't seen any discussion of this and don't understand RSS well enough to see what kind of problems it might run into. Before I put in time trying to figure it out, I just thought I'd ask this is plausible or if I'm barking up wrong tree.

Thanks for any help!

Answer

The WebRss in each web INCLUDEs the TWiki.WebRssBase topic. That one does the bulk of the work, it has a regular expression SEARCH for ".*".

This can be customized easily. You could add a URLPARAM to the SEARCH, then pass the search string to the parameter of WebRss.

Example:

• Set this search twice in TWiki.WebRssBase:
  %SEARCH{ "%URLPARAM{"search" default=".*" }%" web="%INCLUDINGWEB%" ... }%
  Note: The default=".*" parameter requires the latest TWikiAlphaRelease. Alternativly create a CustomWebRss topic just for the custom feed with the search parameter.
• RSS feed for topics containing "mod_perl" in this web:
  http://www.twiki.org/cgi-bin/view/Support/WebRss?skin=rss&search=mod_perl&contenttype=text/plain
  Note: Omit the contenttype paramter to get the feed encoded as XML instead of plain text
