ok, i've started to work with hpricot. i'm debating if i should use 
open-uri or watir. but thats another discussion. my current issue is, 
though, with xpath. this is what i have so far...

#!ruby
require 'watir'
require 'open-uri'
require 'rubygems'
require 'hpricot'


Watir.options_file = 'c:/ruby/options.yml'
Watir::Browser.default = 'ie'

test_site = "http://www.google.com"

br = Watir::Browser.new

br.goto test_site
br.text_field(:name, 'q').set("Dungeons & Dragons")
br.button(:name, 'btnG').click

doc = Hpricot(br.html)

#after the above, i'm trying to store all result elements in an array

x = Array.new
x << doc.search("//li[@class='g w0']/h3/a")

the XPath checker in firefox shows that I have the right path. but the 
command doesn't work in irb. how do i drill down to specific elements so 
that i can extract the title text and url? and wats wrong with my 
xpath??

plz help!
