Assuming it’s not a spoiler, following is the contents of the first

Sure there is.

require ‘rubygems’; require ‘hpricot’; require ‘open-uri’  
doc = Hpricot(open(‘[http://www.unix.org/version3/apis/cu.html](http://www.unix.org/version3/apis/cu.html)’))  
puts (doc/“p.tent/i”).map{|i|i.inner\_html}

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

Thanks Why!
