Hpricot

A Fast, Enjoyable HTML Parser for Ruby

Hpricot is a very flexible HTML parser, based on Tanaka Akira's HTree and John Resig's JQuery, but with the scanner recoded in C (using Ragel for scanning.) I've borrowed what I believe to be the best ideas from these wares to make Hpricot heaps of fun to use.

 #!ruby
 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

A Proper Start

• InstallingHpricot, both stable and development versions.
• AnHpricotShowcase with recipes for most common things. (Also translated to Japanese.)
• The del.icio.us' hpricot tag is quite active, with a wealth of tutorials and other libs.

The Tougher Things

• Stumped? Ask your question on HpricotChallenge.
• The complete documentation, generated from RDoc.
• Wonder what's happening? Check the CHANGELOG and the Timeline

If you're on a machine with a compiler, you can give the Hpricot quickstart a try: http://balloon.hobix.com/hpricot.
