I had a situation where I only wanted to format items in a list that matched a particular regex. I could not find any way to utilize the exclude attribute and define a negative regex (e.g. exclude everything that does not match a regex). It seems the natural counterpart of the exclude option would be an include option.

See also TWiki:Plugins.TopicDataHelperPlugin, this plugin helps with this kind of filtering.

Wow this one was easy but slipped under the radar for almost a year.
