I suppose you're correct, since I don't really know what I'm doing.  =)
To be honest, I've just tried following some sites & tutorials on site
scraping as I'm just trying to grab some info from a vBulletin forum. 
I've been able to pull single items from multiple pages fine but this is 
pulling multiple items on the page.

You can see the sample of what I'm pulling on the above link but here is
my code:

require 'nokogiri'
require 'open-uri'
require 'csv'

@thread = Array.new
@thumb = Array.new

files = CSV.read("urls.csv")
(0..files.length - 1).each do |index|
puts files[index][0]

#load HTML to Nokogiri
doc = Nokogiri::HTML(open(files[index][0]))

#find the hyperlink
threadtd = doc.css('tbody#threadbits_forum_406 tr td.alt2 a').map {
|link| link['href'] }

#find the div with the background img
thumbtd = doc.css('tbody#threadbits_forum_406 tr td.alt2 a div')

  @thread << threadtd
  @thumb << thumbtd

end

CSV.open("thumbs.csv", "wb:UTF-8") do |row|
  row << ["Thread", "Thumbnail"]
  (0..files.length - 1).each do |index|
    row << [
      @thread[index],
      @thumb[index]]
  end
end

The output that I see is fine (though, I'd like to pull the
'background:url()' value rather than the whole empty div) but in the
CSV, it's grouped in the one row and the div's aren't comma separated:

Thread,Thumbnail
"[""http://LINK1"", ""http://LINK2"", ""http://LINK3"",
""http://LINK4""]","<div 1></div><div 2></div><div 3></div><div
4></div>"

Again, I'm sure I'm screwing up or leaving out something important and I
apologize if it's something that should be obvious!
