Hi Everyone,

I am new to Ruby and trying to use it to parse XML files so that I can 
verify that name/value pairs in two (or more) XML files are defined 
consistently

I have been trying to use the rexml API
http://www.germane-software.com/software/rexml/

The website has been down a lot lately and I haven't found too many 
other sources for information

Here is a snippet of my code

require "rexml/document"
include REXML

file1 = File.new( "test.xml" )
doc1 = REXML::Document.new file1
names1 = XPath.each(doc1, "//name") { |e|}
values1 = XPath.each(doc1, "//value") { |e|}
now I can parse names1 and values1 and then do the same for the second 
XML file.
This approach is not great because it does ensure that the name/value 
pairs are siblings.

I am wondering if there is a better way to do this.

Any help would be great appreciated. BTW - I would welcome articles on 
using Ruby for configuration, release and deployment management on CM 
Crossroads (www.cmcrossroads.com)
