Then how can I free those TDOMNodeList objects? I.o.w. how can I get access
to them?

Some time ago I updated the English page of Wiki tutorial to reflect

Yep, just re-read the article and saw the note...

I tried that, and it wordk like a charm.
However can I use that approach if I want to create more complex XML files?

Eventually I want someting like this:
<?xml version="1.0"?>
<root>
  <version>foo bar version 0.0.1</version>
  <children>
    <child id="0001">
      <foo>Bart</foo>
      <bar>me, myself and I</bar>
    </child>
    <child id="0002">
      <foo>Bob</foo>
      <bar>blah</bar>
    </child>
 <children/>
</root>
