Hi Peter,

What you want is to get the array of specific nodes, isn't it??
If it's true, see code below:

xmltest.rb :
require 'rexml/document'

xmlin = <<EOD
<a>
  <b>one</b>
  <c>two</c>
  <d>
    <e>three</e>
    <f>four</f>
  </d>
</a>
EOD

xml = REXML::Document.new(xmlin)
puts xml.elements.to_a('/a/d')

--
then, you can iterate with the nodes of 'd', including knowing
the number of 'd' nodes with '.size' method, right??

Regards,
