You can safely assume most websites will *not* give you access to their database and in general they usually don't like people using _their_ content either. (Never mind the legal issue here)
BUT, if you really want to *rip* content from a different site, you could do so with
HttpUnit for instance. I've used it for moving legacy webpages and it works quite well if you know what kind of
pattern you are looking for.
But perhaps it'd be best if you contact the "target" website first.
