It used to be the case that it was a huge challenge for the average person to grap SEC XBRL financial filings from the SEC web site. An RSS feed was provided for the last 100 filings.
No longer. The SEC is providing an archive of filings by month! You can get to those archives here:
http://www.sec.gov/Archives/edgar/monthly/
The format of each archive is simply an RSS feed. You can read through those filings with anything which will read XML.
Thank you, thank you, thank you SEC!
By the way, for those who like dinking around with stuff, there is a boatload of information which can be accessed using FTP. See here for more info: http://www.sec.gov/edgar/searchedgar/ftpusers.htm
