Subject: Recursing XML data using REXML

Hi,

I would like to process an XML file using REXML and recurse down through
some sub elements, e.g. the "group" and "cond" elements in the following
XML:



<rule>
        <name>Test Rule</name>
        <description>This is a test rule</description>
        <order>2</order>
        <group operator="all">
                 <cond name="condition1"/>
                       <group operator="not">
                             <cond name="condition2"/>
                                  <group operator="not">
                                      <cond name="condition3"/>
                                  </group>
                       </group>
       </group>
            </rule>

However, I need to produce output that maintains the hierarchy so it can
be displayed as a nested list  such as:-

<h1>Rule Name - Test Rule</h1>
<h1>Rule Description - Test Rule</h1>
<ul>
<li>group operator is all - condition name is condition 1
  <ul>
    <li>group operator is not - condition name is condition 2
      <ul>
        <li>group operator is not - condition name is condition 3</li>
      </ul>
    </li>
    </ul>
</li>
</ul>

I can't seem to find any examples of doing this, would somebody be so
kind as to provide me with an example of how I could do this?

Regards,

Carl
