[Skunkworks] RSS feed

Hallo from the cold...... :-) Have a few hours to kill, so am reading about RSS feeders and I have a question for anyone who has done manual creation of such. How do you get the RSS feed to auto update? Say you create the necessary xlm file with the RSS tag and obviously there has to be a file open>filewrite>not overwrite>filesave option to create an auto update of the xml file. Is this sequence correct? Rgds.
