i want to create a feed from existing web page for authorised users only.
i know some basics about rss but don't know how to include dynamic content generated on page to be added in feed.
for example i have small message board and i want to create rss feed from replies to that post, what should i do?
i have created rss feed by creating xml file but that is just static content. do i have to use some php package like simpleXML to create feed xml file on the fly with current data?
i am confused.
please guide me in right direction.
