I found only Ruby language example to use rubyful\_soup.  
I don’t know if there’s a working example for RoR…

Basicall, I’ve done the following:

# in my controller, modified from someone’s blog

class GethttpController \< ApplicationController

require ‘net/http’  
require ‘uri’

require ‘rubygems’  
require ‘rubyful\_soup’

def fetch(uri\_str, limit = 10)

# You should choose better exception.

raise ArgumentError, ‘HTTP redirect too deep’ if limit == 0

response = Net::HTTP.get\_response(URI.parse(uri\_str))  
case response  
when Net::HTTPSuccess then Net::HTTP.get(URI.parse(uri\_str))  
when Net::HTTPRedirection then fetch(response[‘location’], limit - 1)  
else  
response.error!  
end  
end

def test  
@soup=nil  
@result=nil  
markup=nil  
markup = fetch('[http://www.ibm.com](http://www.ibm.com))  
@soup = BeautifulSoup.new(markup)

end

# end

In my view, only one line

Title:\<%= @soup.html.head.title.string%\>

================================================

the above code can run once and output right data.  
But if I refresh my browser, it’s not gonna work “again”.  
and I will encounter error messages

# from my log

ArgumentError (wrong number of arguments (5 for 1)):
