I am looking for an API or data point from which I can get the list of featured or good articles in structured format. The list of featured articles is present here http://en.wikipedia.org/wiki/Wikipedia:Featured_articles. But since it is in HTML manipulating the list is too tiresome as I am trying to classify the articles according to the categories. Is there some place where I can get a JSON/XML file of this list? Or any API?
You can use the categorymembers API to fetch the list from Category:Wikipedia featured articles. That will be the list of talk pages, not the articles themselves, but it's just trivial text manipulation from there.
