Web Scraping with Nokogiri (6)

Yet another example.

require 'open-uri'
require 'nokogiri'

#url = "http://psk31.cocolog-nifty.com/digitalmode/"
url = "http://psk31.cocolog-nifty.com/digitalmode/2017/09/2017-6e90.html"

loop do
  charset = nil
  html = open(url) do |f|
    charset = f.charset
    f.read
  end

  doc = Nokogiri::HTML.parse(html, nil, charset)
  url = doc.css('.entry-nav').css('a').attribute('href').value
  if url == 'http://psk31.cocolog-nifty.com/digitalmode/' then
    break
  end

  print '<span style="margin-right: 20px">' << doc.at_css('.entry-nav + h2').text << '</span>'
  print doc.at_css('.entry-nav').at_css('a').to_html.gsub(/« /, "")
  puts '<br>'

end

Initial URL is manually adjusted to keep the code simple.
