Nokogiri Examples

nokogiri.rb

Nokogiri::HTML.parse(open(url)).css('.tn a').collect {|img| img["href"]}

#open(url) - opens and returns an html document
#css('selector') is just like jquery except server side. It returns a (ruby equivalent of a) linq-like enumerable
#collect is the same as .NET's select function

#So this one line when I set url to a Craigslist listing detail page will open that page and return an array of images for that listing.
