22119 Website Generator

I need a script or software to create pages from a datafeed provided by a merchant. The datafeeds are all the same structure and are in a txt file format. Datafeeds have up to 100k items in them. The template should be editable, and should break down the datafeed into tags so I can customize the template. Each page should have a next and previous link on them. The script should also generate a sitemap so all the links are there. I'll need two different variations of this since I want to use it for 2 seperate affiliate networks that have different datafeed structures. If you have worked with page generation scripts you should find this easy. Please don't bid if you don't 'get it' :)
