There's a contradiction, somewhere (?)

"One-click" 1.8.2-15 Stable Release  (April 20, 2005) has REXML 3.1.2.1
 in Ruby 1.8.2 final (2004-12-25).


require 'rexml/document'
puts 'ruby %s (%s) [%s]' % [RUBY_VERSION, RUBY_RELEASE_DATE, RUBY_PLATFORM]
puts REXML::Version

xml = REXML::Document.new(File.read('D:\ruby\DfB\TEMP\clruby\___test.xml'))
mi = REXML::XPath.match(xml, '//HomesiteTree/Builder/Division/Workflow/Milestone')

mi.each { |e| print ' ', e.elements['MsMilestoneId'].text }; puts

I *know* I'm using 3.1.3  :)

It fixes several bugs relating to XPath result ordering.
The REXML tracker is down as I write, otherwise I'd give a link.

If you're sure you're getting incorrect results using 3.1.3,
please submit a bug report to:
http://www.germane-software.com/projects/rexml/

As you can see from my tests - the 2nd result array is in order.

The disorder of the 1st result seems to be different from yours
(first element of <80>) but maybe there's a random factor
associated with the bug in 3.1.2.1 (?)
