Scrap UK top 40 singles chart from BBC

#!/usr/bin/env ruby

it turns out that BBC website has a printable version of the top 40 UK singles chart, that made me jump of joy :D

require 'open-uri'

get BBC singles chart printable version

page = open('http://www.bbc.co.uk/radio1/chart/singles/print').read

result has data as table so we'll extract keys from TH tags

keys = page.scan(/<th>(.+)<\/th>/).map{ |k| k.first.downcase }

extract cells from TD tags

cells = page.scan(/<td>(.*)<\/td>/).map{ |c| c.first }

split cells to arrays each equal to keys

rows = cells.each_slice keys.size

container to join data as Hash objects and push to it

data = []

now iterate on each row and join keys with their respective values then convert them to arrays

rows.each do |row|
  data << Hash[ [keys, row].transpose ] # this is a good trick ;)
end

show us what you got sir.

puts data
