What is behind RSS technology?

I am certified in XML, from that point wouldn't RSS (Really Simple Syndication) be a breeze?





A lot of people ask for this in job descriptions so it may be worth me doing an attempt at it?

What is behind RSS technology?
to my understanding you would simply make an xml page with the relevent dynamic data. That is it! Then an RSS reader will check your XML page to see if any of the fields have changed and report that back to the user who entered your URL into their RSS reader. The XML pages I have looked at (i never made one) look like very basic xml files. Look at the source on some RSS links you will figure it out fast. Also w3c schools has an allright section on it.
Reply:I've been writing RSS feeds since RSS was brand new!





The entire family is worth knowing (rss .90 -%26gt; atom 3). I woudn't hire a programmer who didn't know dozens of xml apps and formats!
