screen scraping to
create rss feeds
focused on small bits of
information.
Feedcatch
RSS feeds aren't designed to retain every update they publish. If they did,
they'd be very, very long. Most RSS feeds contain information on only the
last 10 to 20 items that have changed on a Web site. If you ind yourself in a
situation in which you know you will need the contents of an RSS feed for
an upcoming project, but you don't quite need it yet or don't have the time
to keep up with it, try Feedcatch (feedcatch.feedshake.com), a free service
of Feedshake.
To use Feedshake, you enter the URL of the feed you want to archive, and
then specify the maximum number of items you want to keep in the RSS
feed and the number of hours old the contents of the feed can be. If you set
both of those parameters to 0, Feedcatch will create a feed that stores its
contents indeinitely.
