Convert HTML from input files (or standard input, if no file name given) to CSV. Taken from a stackoverflow.com answer I lost since.

html to csv in ruby

#!/usr/bin/ruby
require 'nokogiri'

doc = Nokogiri::HTML(ARGF.read)

doc.xpath('//table//tr').each do |row|
  row.xpath('td').each do |cell|
    print '"', cell.text.gsub("\n", ' ').gsub('"', '\"').gsub(/(\s){2,}/m, '\1'), "\", "
  end
  print "\n"
end
