Downloading all public articles from a blog
I am looking for a way (for academic research) to download all articles from a blog in XML/JSON format. Is this somehow possible? I know of the RSS feed mentioned on http://www.livejournal.com/bots/ but then I only get the most recent articles from a blog, not all of them.
I would also be interested in a way to get a specific article's content in XML/JSON format, if I know the direct URL to it. I haven't found a way to do this (other than, again, the RSS feed, but the article might not be listed in the feed as it shows only the recent articles from that blog).
I am new to LiveJournal so any help is highly appreciated :) Thanks!
