Getting variable yet most immediate parentNode

XML=

The general gist of the below application is to output a survey and
all its questions, and give the user the appropriate options
(answers).

Problem: given the variable relationship between the <answer> nodes
being matched and their parent <section>, how to reliably amtch the
correct section @name?

<root>
   <section key="A" name="Survey 1">
      <answers>
         <options />
      </answers>
      <questions>
          <answers />
          <question>
                <answer>
                    <option>True</option>
                    <option>False</option>
                </answer>
           </question>
      </questions>
   </section>
</root>
