[Zope] Newbie question...

Hi... Please excuse me for this probably simple question, but I'm new to Zope and Python and didn't found the answer in any Zope documentation or in this mailing list archives. So how, in DTML or Python, can I "include" the output of a Zope object which name is passed as an URL's argument (for example: http://www.blabla.com/folder?content=myobject) ?? Thank you for any help... Thierry
