Heh...I just registered so I could post on the roughly the same subject, 
but this seems to work:


#!/usr/bin/ruby -w

require 'rexml/document'
include REXML

file = File.open("forum.xml")
doc = Document.new file
root = doc.root

root.elements.each("doc/field[@name='prodId']") do |element|
    puts element.text
  end
