There is a program called webmerge that allows you to
publish datafeeds as html.
You have to set up templates and how the menus work, etc.
You can also use php to load it into a mysql database and
generate the pages on the fly (or, if you really want to,
generate static html pages on your server)
There are also php scripts around to do this for you
(can't remember which ones at the moment)
note that datafeeds can need "cleaning" - bad data, pricing at zero, etc.
