The following Module will return raw text file from the SEC website for the last available Form DEF 14A.
This file contains SGML, HTML and uuenconde jpgs or gifs or pdfs.
I tried processSECDEF14A["GE"] and processSECDEF14A["MSFT"] with success.
The code need to be tighter for when cases fail. And Parsing the HTML between <TEXT> </TEXT> tags is left for review.
The bulk of the data mining for key terms such as "Summary Compensation" and look for the HTML Tables near those terms.

I'm just flying by the seat of my pants. I will try your suggestion. I need compensation tables from the DEF 14A. I spoke to a SEC representative yesterday, and she told me that DEF 14A is not yet available in XBRL format. I like your download-to-notebook-format idea.
Thanks once again,
