妳想parse的是xml 時妳有更好的選擇libxml
require 'pp'
require 'benchmark'
require 'rubygems'
require 'xml/libxml'
require 'hpricot'
require 'rexml/document'

include Benchmark

signal_keys = [:signal_type, :create_datetime, :realized_or_unrealized,
 :close_datetime, :open_price, :close_price, :performance,
 :annualized_performance]

$rsp1 = {}
$rsp2 = {}

bm(12) do |test|

 str = File.read('test.xml')

     test.report('libxml') do
     #xml_doc = XML::Document.file('test.xml')
     xml_doc = XML::Parser.string(str).parse
     root = xml_doc.root
     root.find('target').each do  |t|
     $rsp2[t.find_first('target_id').content] = rsp_target = {}
     rsp_target[:target_performance_average] = t.find_first('performance_average').content
     rsp_target[:target_annualized_performance_average] = t.find_first('annualized_performance_average').content
    
     t.find('signal').each do |signal|
       rsp_target[signal.find_first('signal_id').content.to_sym] = signal_keys.inject({}) do |h,k|
         h[k] = signal.find_first(k.to_s).content ; h
       end
     end
   end

 end

 test.report('hpricot') do
   xml_doc = Hpricot(File.open('test.xml'))
   (xml_doc/:target).each do |t|
     $rsp1[t.at(:target_id).innerHTML] = rsp_target = {}
     rsp_target[:target_performance_average] = t.at("performance_average").innerHTML
     rsp_target[:target_annualized_performance_average] = t.at("annualized_performance_average").innerHTML  
     (t/:signal).each do |signal|
       rsp_target[signal.at(:signal_id).innerHTML.to_sym] = signal_keys.inject({}) do |h,k|
         h[k]=signal.at(k).innerHTML  ; h
       end
     end
