Hi Jesus,

Thanks for your reply. That really helped.

You are of course correct.
I have followed your suggestion, installed 'nokogiri' and am currently 
looking at some examples. I will then tweak what you wrote and use that 
in my final version as it is very neat and concise.

However, this:

> doc.xpath('//tr[@class="odd"]/td').each_slice(2) do |first, second|
>   result << [first.inner_html, second.inner_html]
> end

gave me the idea of writing this:

lines.each_slice(4){|one,two,three,four| result << 
[two.chomp,three.chomp]}

which also does exactly what I want, so thanks again!

Essentially, I have just finished reading the first part of the Pickaxe 
book and am trying to implement some of their suggestions and think 
about the code I write as opposed to doing the "quick and dirty" method.
