Forum: RForum Scrubyt fails

Hi there,

I'm trying to use Scrubyt for my project however it fails on me.  I took
the source code sample from the Wiki:

---

require 'rubygems'
require 'scrubyt'

google_data = Scrubyt::Extractor.define do

   #Perform the action(s)
   fetch 'http://www.google.com/ncr'
   fill_textfield 'q', 'ruby'
   submit

   #Construct the wrapper
   link "Ruby Programming Language" do
      url "href", :type => :attribute
   end

   next_page "Next", :limit => 2
end

puts google_data.to_xml

For some other code, I'm getting:

I found few similar error posts, but not replies.  Did somebody manage
to fix that?  I really like what Scrubyt can do, but it doesn't work for
me.  So could you otherwise advise me an alternative to it as well?

Thanks.

Hey,

got the same problem. Did you find a solution?
