# Nokogiri parses and searches XML/HTML very quickly, and also has
|
||||
# correctly implemented CSS3 selector support as well as XPath 1.0
|
||||
# support.
|
||||
#
|
||||
# Parsing a document returns either a Nokogiri::XML::Document, or a
|
||||
# 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|
|
||||
# puts link.content
|
||||
# end

||||
