Also, I'm using XML to store some articles and things, and I wondered if there is any way in which I can link the data in my other XML files to the RSS feed, rather than having two separate XML files with the same data in - one for the data and another one for the RSS feed? As it stands I've basically got the same data stored twice.
I guess I'd like to be able to take some of the data in one XML file and use that as the 'description' in my RSS feed, for example.
