Ive got a ruby script to login and parse my forum as follows

require 'rubygems'
require 'scrubyt'

#only the following parts should need editing
baseurl = "http://www.myforum.com/" 
username = "bot"
password = "botpasss"

data = Scrubyt::Extractor.define do
   fetch "#{baseurl}?action=login"
   fill_textfield 'user', username
   fill_textfield 'passwrd', password
   fetch "#{baseurl}?topic=672"
   link '//div/code'

data.to_xml.write($stdout, 1)
puts data
When I run it, it returns
My question is how do I get it to just give me the "http://rapidshare.com/files/example/example.rar" part or how do I perform a function to do this?

Any help will truly be appreciated Thanks
