[Zope] Lookinf inside page templates from a script

[Felix Ulrich-Oltean]

Hi

I'd like to get the names of all the macros in a pt and of all the
slots within each macro, but I'm getting guarded_item errors.

In PageTemplate.py, I have found pt_macros(), which returns a
dictionary with macro names as keys.  Great so far.  I can even print
pt_macros() and get a string representing the whole dictionary.
However, when I try to access the corresponding value so I can look
for the slots inside each macro, I get the error shown below.  Is
there a way of gettting the macros and their slots from a script, or
do I have to write an external method / product?

Thanks

Felix.
