[as a side note, there's a zope-xml@egroups.com list that's about Zope
and XML..it may be easier to direct your questions on XMLDocument there]

What is going on is that your display method picks up text nodes as well;
they don't contain much text beyond whitespace, but there's there between
the element nodes. You can do something like this to skip them:

<dtml-in "getChildNodes()">
  <dtml-if "getNodeName() != '#text'">
  <p><dtml-var absolute_url></p>
  </dtml-if>
</dtml-in>

A more advanced option is to use my XMLWidgets product, to be found here:
