[Zope] Dynamic DTML

[peter sabaini]

i use this; i got a class:

  -- snip --

class DTMLStringAttribute(PlainTextAttribute):
     'An attribute which renders itself as a DTML Template (i.e. it 
returns an object)'
     def render(self):
         s = self.d
         h = Globals.HTML(s, __name__='DTMLStringAttribute_%s' % self.name)
         return h

  -- snip --

ie. i instantiate a Globals.HTML object with a string s (containing 
DTML). you can then call this object to get it interpreted.

caveat: this is rather slow. use sparingly.

cheers, peter.
