[code] Parse XML in Ruby

Needed to call an xml feed bunch of times for work to prototype some algo. I just love how easy this is in Ruby.

require 'rexml/document'
require 'open-uri'
require 'cgi'
include REXML

def searchOne(searchTerm)
  searchURL = 'http://foo.com/?q='+CGI.escape(searchTerm)
  searchResult = REXML::Document.new(open(searchURL).read)

  searchResult.root.each_element do |level0|
     level0.each_element do |level1|
       if level1.name == 'IWantThisNodeType'
         print level1.text + "\n"
         level1.each_element do |level2|
           # Do something interesting
         end
       end
     end
  end     
end

searchOne('foobar')
