#simple ebay example

require ‘rubygems’  
require ‘scrubyt’

ebay\_data = Scrubyt::Extractor.define do

```
 fetch 'http://www.ebay.com/'
 fill_textfield 'satitle', 'ipod'
 submit

 record "//table[@class='nol']" do
   name "//td[@class='details']/div/a"
 end

```

end

puts ebay\_data.to\_xml

when I run ‘ruby ebay\_3.rb’ I get:

C:\ruby\>ruby ebay\_3.rb

what should I do?  
do I have to reinstall the gems scrubyt etc? does ruby need to be  
reinstalled? Does this have something to do with windows? should I be  
running this on a linux platform instead? (or maybe I should just get a  
mac).
