In Python 1.5.2, you use the "find" function in the module "string".

The "string" module is exposed as "_.string" in DTML.

I cannot tell you why it does not work for you in Zope.

I can tell you that regular expressions in External Methods
are treated the same way as in external scripts (with one
notable exception: you should not use compile regular expressions
in default function arguments).
Especially, there is no problem with '"'.

Looks like unbalanced "()":

  In the "url" definition, I see 2 opening but one closing parenthesis.
