Assuming it's not a spoiler, following is the contents of the first
column of the table at that URL. (There's no joy in trying to
parse/string HTML.)

Sure there is.

require 'rubygems'; require 'hpricot'; require 'open-uri'
doc = Hpricot(open('http://www.unix.org/version3/ap...'))
puts (doc/"p.tent/i").map{|i|i.inner_html}

Hpricot makes HTML scraping fun again (no, really!).

Thanks Why!
