[Zope] python ignorance shining through...

[Phil Harris]

Hi tone

If I understand correctly you want to get the contents of an object but you
only have the name and not a reference to it, correct?

If that is the case then try this:

try:
   template_str = eval("self.RENDER.%s.read_raw()" % tagclass)
   template = DocumentTemplate.HTML(template_str)
   theresult = template(self, content=content)
   return theresult
except KeyError:
   return "no renderer for %s" % tagclass

The eval will take a string and evaluate it in the current context, this
should use the contents of tagclass to create a callable reference to that
tagclass object.
