thanks for the reply, however that particular example and most of the one's i've seen deal with publishing an rss feed of the latest topics. What i want to do is integrate an rss feed into the board so it appears to be a forum / topic list.
think i'm going to have to write this myself using a cron job / custom script to insert the rss items into the phpBB database.
if you want to keep the rss feeds in your database for a longer time then they are within the rss feed itself, it would be a good idea to insert them into your forum.
if not, you should be able to use the phpBB template system to display the rss-feed's data within the standard forum design with not so much problems. they got loops over arrays etc. and this comes in handy for that task.
To be honest I would prefer not to insert them into the database at all, just parse them on the fly. Think i'll need some sort of cron job to retrieve the xml files, or a cache set up, or i'm going to end up annoying a lot of people.
Think i'll have a dig through phpBB and find out more about how the forum's are displayed, in the meantime if anyone has any ideas for the points above i would be greatful
