[RAILS] Scraping for beginners (Ruby)

I did scraping for the first time, It worked, so I'll leave it as my memo.

yahoo_scrape.rb


require 'open-uri'
require 'nokogiri'

url = 'https://www.yahoo.co.jp/'
 

doc = Nokogiri::HTML(open(url))
 
puts 
doc.css('h1').each do |link|
  puts link.content
end
