Subject: Parsing XML into a complete domain object

Recently at work we've decided to attempt to build a basic XML driven 
automation framework to work with Watir (a web development testing 
library for ruby).

I cant figure out how to loop through each level of the REXML document 
to extract the data needed to build the complete object.

It seems that if i try to use any iterators on a root.elements[] object 
it converts it to text so i can't nest another iterator or loop to 
access the innards.

my only recourse has been to resort to a ton of nested while loops which 
is ugly when compared to most other ruby loops.

eg.
i = 1
while root.elements['cases'].elements[i] != nil

 n = 1
 while root.elements['cases'].elements['test-case'] != nil

   #more loops here. continue down the chain until i can build the
   #object from the inside out.

 i = i+i
 end

i = i+i
end



my xml looks like this
<script>
<project-name></project-name>
<start-url></start-url>

 <test-case id="1">
  <test-step id="1">
   <test>
    <interaction>double click</interaction>
    <element>
     <name>button 1</type>
     <type>button</type>
    <element>
   </test>
   <check>
    <element>
     <name>Page title</type>
     <type>text</type>
    <element>
   </check>
  </test-step>

  <test-step id="2">
    ...
  </test-step>
 </test-case>

 <test-case id="2">
  ...
 </test-case>
</script>

somehow i have to get THAT modeled into an object
script object contains test-cases, test-cases contain test-steps etc....

Any thoughts? (sorry for the long post... its kinda hard to explain 
without showing EVERYTHING.
