# should skip loading xml jars. This is because those are in WEB-INF/lib and

# Nokogiri parses and searches XML/HTML very quickly, and also has
# correctly implemented CSS3 selector support as well as XPath support.
#
# Parsing a document returns either a Nokogiri::XML::Document, or a
# Nokogiri::HTML::Document depending on the kind of document you parse.
#
# Here is an example:
#
# require 'nokogiri'
# require 'open-uri'
#
# # Get a Nokogiri::HTML:Document for the page we’re interested in...
#
# doc = Nokogiri::HTML(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
#
# See Nokogiri::XML::Node#css for more information about CSS searching.
# See Nokogiri::XML::Node#xpath for more information about XPath searching.
