Subject: Unit Testing with REXML questions

Hello all,

I'm using REXML to build some XML from a rails app.  I'm unit testing
the output also using REXML... and I have these questions :

Given

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

I want to use XPath to tell me how many <d> there are under <a> ?

I want to use XPath to iterate the _names_ of the items under <d>
(Does this make sense in XML World.  This one is not necessarily a
requirement, but I uncovered this need while experimenting in IRB.) ?

Thanks in advance!
