Rendering means "calling".

Please read "Calling DTML objects" in

  <http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html>

to learn everything about calling DTML objects.

Other types of objects (e.g. Page Templates) are easier to call/render.

Why?

   You can add span tags after it has been (Zope) rendered.

Try the following (assuming, "document" is a DTML object):

    hightlight (a Python script, similar for an External Method)

      rendered= context(context.aq_parent,container.REQUEST)
      # now do your highlighting on "rendered"
      ...
      return rendered
