The previous entries seem to be focused on
reading and displaying RSS feeds from other sources.
I'm contemplating on generating feed info based on internal x-cart newsletter items.
It shouldn't be too difficult to have a PHP script make a query from the database, and write out an XML file.
Anyone thinking trying this idea out? It would be a great addition to those X-cart users that have events, new products, sales etc. that they would want folks to know about. Now users can only subscribe to e-mail, which can easily get lost in the deluge of SPAM we all face these days. This could be a viable alternative.
I'll start investigating what it would entail to add a PHP script to generate a feed. Any one want to help, feel free to jump aboard
