Installable with the Extension Manager


A macro that aggregates RSS feeds in a single table.



See also Jerome's Blog post on this macro.



Prerequisites & Installation Instructions

We recommend using the Extension Manager to install this extension (Make sure that the text "Installable with the Extension Manager" is displayed at the top right location on this page to know if this extension can be installed with the Extension Manager). Note that installing Extensions when being offline is currently not supported and you'd need to use some complex manual method.

You can also use the following manual method, which is useful if this extension cannot be installed with the Extension Manager or if you're using an old version of XWiki that doesn't have the Extension Manager:

  1. Log in the wiki with a user having Administration rights
  2. Go to the Administration page and select the Import category
  3. Follow the on-screen instructions to upload the downloaded XAR
  4. Click on the uploaded XAR and follow the instructions
  5. You'll also need to install all dependent Extensions that are not already installed in your wiki

Release Notes


  • Support for HTTP Basic Authentication with URLs in the form http://user:[email protected]/feed
  • Message when there is an error retrieving a feed
  • Preventing index out of bounds error when no items are read
  • Translation of example table titles to English


I replaced the line 

entries.keySet() as List).reverse()[0..20].each() 


def mysize = entries.keySet().size()
(entries.keySet() as List).reverse()[0..mysize-1].each()

in order to prevent the "IndexOutOfBoundsException" in case there are less than 20 results to display.
