well, I knew it existed before but I realised how *I* could use it just this afternoon.
I have a subscription section to my education site and I thought that I could have an RSS feed to show my users which materials have just been added. So I made a xml document, called it new.rss and was off and running in ten minutes.
As I am clueless when it comes to php, asp and so on, all I have done is to use the WebmasterWorld rss doc as a template and hand edited in a text editor. Is that cheating?
Are these feeds only really meant for dynamic sites and is hand writing them just defeating the whole point?
Will be adding probably 3-5 new materials a week to the doc. Am I overkilling? Just happy to have lost my RSS virginity to be honest...
One important thing to note is that RSS is XML, and XML is much stricter than HTML in terms of well-formedness. To avoid problems especially with hand-rolled feeds, you must check your work with an RSS feed validator [feedvalidator.org] - a malformed feed can cause a fatal error. Personally I prefer using RSS 2.0 over the rather ancient Netscape RSS 0.91 used in the WebmasterWorld feed (although Netscape RSS 0.91 has its advantages too).
I downloaded a RSS reader and mine came through looking fine and I did validate it too. I will only infrequently be adding to it..it's more of a service to my paying customers than anything else. And it's good for me to get into this new technology too - even if in a very non-standard way.
