|
||
# Nokogiri::HTML4::Document depending on the kind of document you parse.

# Here is an example:
|
||
#
|
||
# require 'nokogiri'
|
||
# require 'open-uri'
|
||
#
|
||
# # Get a Nokogiri::HTML4::Document for the page we’re interested in...

#
|
||
# doc = Nokogiri::HTML4(URI.open('http://www.google.com/search?q=tenderlove'))

#
|
||
# # Do funky things with it using Nokogiri::XML::Node methods...
|

#
|
||
# ####
|
||
# # Search for nodes by css
|
||
# doc.css('h3.r a.l').each do |link|
