[Zope] PYTHON: Searching for an object inside a folder

[Tino Wildenhain]

Hi Vitor,

this is a faq ;)

Look for documentation on ZopeFind() and ZopeFindAndApply()
(The Zope source is last resort, but also google, Zope.org
and the parameters on Zopes managements "Find" page)

Or see the following example:
