Subject: hpricot and xpath doesn't work like they should ?!?

hi,
I wanted to write me a little console tv-guide with ruby and hpricot. I 
installed the firefox xpath checker plugin and went to 
http://www.klack.de/TvEvening1.php3?HPTFRAME=%2FTvAtEvening.php3 . Then 
I checked the xpath of these senders fields like ZDF and got:

/html/body/table/tbody/tr[2]/td[2]/table/tbody/tr/td/center/form/table/tbody/tr/td[2]/table[2]/tbody/tr/td/table[2]/tbody/tr[3]/th[1]

so I tried to parse the website for this and output the hits but I don't 
get any output. Here's the code:

#!/usr/bin/env ruby

$Verbose = true

require 'hpricot'
require 'net/http'

url = 
URI.parse('http://www.klack.de/TvEvening1.php3?HPTFRAME=%2FTvAtEvening.php3')
req = Net::HTTP::Get.new(url.path)
res = Net::HTTP.start(url.host, url.port) {|http|
      				   	       		 http.request(req)
                                  			  }

tv = Hpricot(res.body)
tv.search("/html/body/table/tbody/tr[2]/td[2]/table/tbody/tr/td/center/form/table/tbody/tr/td[2]/table[2]/tbody/tr/td/table[2]/tbody/tr[3]/th[1]").each 
{ |a| puts a}

#eof


Am I using hpricot in the wrong way? I thought it could handle xpaths?
