Hi Pone, I am after a similar function but for slightly diferent reasons, I want to tag a batch of TV epsidoes in one go like getting an albums tracks.
Anyhow, I have been working on a different approach. I have written a php web service script
(only for IMDB at the moment) that does just what you want, running on a web server.
It acts as a proxy and follows certain links, grabs all the information (from about 9 different pages). The result is either a simple HTML display of the data, an XML file and soon to be a JSON object as well.
I am thinking about adding other scrapers so maybe able to do something for you.
I am a few weeks away but if anyone is interested in helping me, beta testing or even doing
the mp3tag scripts to scrpae from the XML, then let me know.
