slightly OT: how to search amazon?

[Chris Sheffield]

Hope no one minds if I ask this here. I'm having a hard time finding much in my searches for how to do this.

Does anyone know how one would go about searching for product info on amazon.com via a custom url? If I wanted to include a search in an app by using isbn, key words, etc., what's the best way to do that? I've found information on how to create a search url, but that just loads a search results page, viewable in a browser. Is there a way to modify the url so that it grabs some nicely formatted search results, rather than html for a web page that has to be parsed to get the info I need?

Mostly what I'm trying to do is look up info on books, movies, tv shows, or other products and display relevant information to the user (i.e. author, title, actors, series, etc.).

Thanks,
Chris
