Using XML

[font=Trebuchet MS]So I’m using this ( to display my XML Data and it’s working fine but my question is… How can I set it so that people viewing the Data can scroll back or click a button to view past “nodes” of data.

For example I’m using this to display a list of who’s playing in a show the upcoming weekend. As it is now it just shows the most recent entry, how can I make it so people can view past Cast List?
