This module cleans all the HTML tags from RSS Feeds that you provide on your site.
The type of nodes to clean HTML from is selectable.
The motivation is to make sure that interested feed subscribers would click to your site to visit links.
For Drupal 4.7, a patch for node.module is needed. It is included in the patches directory for Drupal 4.7.3, as well as a prepatched version of the same module for convenience.
