I would like to try to automate this process as much as possible. I need to search for a subject on google news or other news sources, obtain the feed, edit the feed so they are not duped, and place them in a website.
Is there a database of press releases? and is there an application that easily edits these feeds into one rss feed?
There are many tools available for combining rss feeds [google.com]. Probably the best known and most functional is Yahoo Pipes. It can be a bit difficult to understand for the beginner though. Fortunately they have some good examples you can follow.
