Here is some code:

require 'rubygems'
require 'hpricot'
require 'syntax/convertors/html'

hpricot = Hpricot('generate_primes.rb')
convertor = Syntax::Convertors::HTML.for_syntax "ruby"
hpricot.search('//pre[@class="ruby"]') do |e|
e.inner_html = c.convert(e.inner_text, false)
end
puts hpricot.to_s
