Hi, all. I am looking for a computer-parsable list of symbols in various indices, including S&P 500, DIJA, and Russell 1000/2000/3000. I was able to find a web site that lists S&P 500 symbols as a fancy webpage, and I was able to find a PDF published by Russell that lists their symbols across 26 pages of the PDF, but I am looking for a plaintext file that I can use as an input to a computer program that I want to write.
Can anyone suggest where I can get such data files?
