Question

I'm using the infoRSS extension for firefox to receive WebRss updates. But for argument's sake, it could be any RSS reader.

I'd like to be able to filter out topics that I've just edited from the RSS headlines I receive. Afterall, if I made the change then I don't need to see it as a headline. On the other hand, if someone has followed up on my edit, then I do want to see the headline.

Does anyone have experience with filtering WebRss feeds based on author of the most recent rev ?

Updated Question

infoRSS allows you to filter the feeds you see based on any of these conditions :

• headline
• body
• category
• published date
• received date
• read date
• headline #

Is there a way to customize the data that is sent from WebRss ? For example, would it be possible to populate the category field in an RSS headline from the value of a TWikiForms field ?

If you answer a question - or someone answered one of your questions - please remember to edit the page and set the status to answered. The status selector is below the edit box.

If you let InfoRSS do all the filtering you only need to change TWiki.WebRssBase or to create a custom version of WebRssBase. (Plus if you have a new topic with your own WebRssBase, you need to call that one from WebRss)

In your WebRssBase add:

<dc:category>$formfield(Category)</dc:category>$n    

If you want to let TWiki do some filtering (works for categories, not for authors, or I haven't found a way to do that), you would need to create a custom search that you pass to WebRss. I have just done this for BlogAddOn. It looks like this:

%SCRIPTURL{"view"}%/%BASEWEB%/WebRss?search=%ENCODE{"[T]opicType.*value\=.*(BlogPost);[C]ategory.*value\=.*(%URLPARAM{"category"}%)" type="url"}%;regex=on;casesensitive=on;excludetopic=BlogPostTemplate,BlogPost;limit=16;scope=text

You can test these searches if you change WebRss to WebSearchAdvanced.

Actually, you can use the existing WebRss topic, it understands a search parameter as documented in WebRssBase. The search can be any regex, ANDed with semicolon, and negated with exclamation point, such as soap;web service;!shampoo.

Note on performance: TWiki.org is already at 100% CPU; please do not access RSS more than once every 15 minutes if you use a search parameter. A normal RSS feed without search is cached, those with search are not cached.

The filter example I gave above uses the existing WebRss topic. But to add a field for category you will need to make a change or create a new WebRssBase topic.

-- ArthurClemens - 21 Dec 2006

Correct, to change the feed format you need to modify the WebRssBase topic.

To search for the last author, search for META:TOPICINFO.*author.*<name>, such as this feed:

https://twiki.org/cgi-bin/view/Support/WebRss?search=META:TOPICINFO.*author.*PeterThoeny

Hello,

I would really appreciate some help.

I am trying to filter my RSS topics using the following command but it is not working: http://...WebRss?search=2171

I only want to show topics containing the number 2171 but all topics are being shown as normal.

Can anyone help?

Thanks,

Craig
