Hpricot is a very interesting lib to parse HTML. I’ll post here the example, just to check on the beauty of it from time to time…


require 'hpricot'
require 'open-uri'
# load the RedHanded home page
doc = Hpricot(open("http://redhanded.hobix.com/index.html"))
# change the CSS class on links
(doc/"span.entryPermalink").set("class", "newLinks")
# remove the sidebar
(doc/"#sidebar").remove
# print the altered HTML
puts doc


The lib is evolving, being added support for more XPath functions, etc.

RedHanded’s blog from the same author, has another cool example. why rocks!
