This will contain a combination SGML-XML and usually well formed HTML or XHTML in addition to some well encoded image or pdf files.
The HTML file is good for viewing as well as processing but the text file contains some header information.
The wolfram financial data can help if you are doing portfolio research and you only know the ticker.
So from Ticker you want to get CIK from CIK you can go to the SEC or through well formatted URI (URL) for browse edgar cgi you can get the forms for a particular company. So this URL get's just FRES INC lastest DEF 14A
All I did was change the CIK=& to CIK=724571& to get the specific form.
The return list is HTML page an one can easily look for all links the have the word "[text]" on that resulting page
Wolfram's Financial Data or W|A can help getting a list of Executives at a company.
Back to the *.txt file. This is the file you want to process. All of these forms will contain lots of legal blah blah blah text. You want to find the HTML table or segments that contain compensation data. The HTML is daunting but applications such as HTML tiddy may help or simply finding the correct regex pattern to find well formed chuncks of HTML to process will be necessary.
Once you have the tables the rest is linking executives with their CIK and the data and footnotes from the table. The footnotes are needed. The table may say one number and the footnote may explain how to use it or what it really means.
There is more information for retrieving SEC data via FTP or HTML and how to form a URL to get archived data on the SEC website. You may want to pursue these questions offline.
So if you choose to pursue this then welcome to data mining using Mathematica.

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,
