You are looking at the wrong place. For your particular example, check this link: http://www.sec.gov/Archives/edgar/data/1112412/000119312513028328/0001193125-13-028328-index.htm
You can see that the link that you gave us is the complete submission text file, which is not XBRL. The XBRL files are the 6 files at the bottom of the link I gave you.
Hope this helps.
P.S. You should check www.finviews.com, we have already done all the work. We can provide all the XBRL reports directly into Excel, and as soon as a company files its reports (10Q, 10K etc..) with the SEC, it takes us less than 2 minutes to have all the data (main statements to start with) in Excel as the company published, so you can do your financial modelling afterwards.
