Subject: Re: process xml in a page

Thank you, James.  I got a step further, but still need help.

This code outputs exactly what I want to see to the debug window:

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


url = "http://clinicaltrials.gov/show/NCT00001372?displayxml=true"

open(url) { |page| print page.read() }



However, I am having trouble when using the REXML tutorial.  Should I 
somehow save the output to an .xml file locally?  Or should I add the 
output to a string?  I am not sure how to do either as I am having 
trouble directing the "print" output anywhere.


Thank you and sorry for the noobness.  The api I used in a ruby project 
before made everything a bit too easy, so I am still learning.
