  require 'rubygems' require 'nokogiri'    require 'open-uri'  page_url = "a.html"  page = nokogiri::html(open(page_url))     data = page.css("body").text      po_numbers = data.scan(/invoice number : \[\d+\] po number : \[(\d+)\]/).flatten     tracking_numbers = page.css("a").text.split      [["po number", "tracking number"]].concat(po_numbers.zip(tracking_numbers))  puts po_numbers  puts tracking_numbers   => po_numbers = ["4587958", "4567892", "4587958"] => tracking_numbers = ["12543", "12356"]

when zip together, get:

=> po_numbers.zip(tracking_numbers) => [["4587958", "12543"], ["4567892", "12356"], ["4587958", "nil"]]  want is:  => [["4587958", "12543"], ["4567892", "nil"], ["4587958", "12356"] ]

try this

data = page.css("body").text data = data.gsub(" ","").split(/\n/) po=[] track=[] data.each |i|   if i.include? "ponumber"     po << i.split("ponumber:").last.scan(/\d+/)[0]   end   if i.include? "trackit"     track << i.split("trackit:").last   end end po.zip(track)
