How To Create RSS Feeds
In Drupal 7, core node module provides basic RSS publishing for content. An RSS feed is generated at /rss.xml. By default, the RSS feed will take the 10 most recently created pieces of content promoted to the front page and respect node access grants to ensure that users only see RSS feed items they are eligible to see.
The admin/config/services/rss-publishing page may be used to add a description to the RSS feed and change the number of pieces of content displayed in the feed.
