Hi! I wonder if you can get acess to all content on a site if they have an rss feed or if you have to do some web crawling to be able to do that.
Take their feed and run it through an RSS parser written in either a server-side programming language or JavaScript. Problem (mostly) solved.
Can I work with the content in the feed if I do this? I mean search for certain keywords so it doesn't return the new articles but the most relevant for a keyword?
That would require some heavy programming mojo, but I'm sure it could be done. It won't be easy though.
