[Zope] Dtml tags complexity [WAS : Re: [Zope] I seem to be missing a "break" DTML tag] DTML tag]

[Pierre-Julien Grizel]

Wow !! Thanks, Phil, this is the more "elegant" way to solve this problem ! 
I guess many of us have once been facing this problem, and your solution is
more "readable" than the other one.


By the way, is there a way to know the complexity of each dtml tag ? 
I mean, is a dtml-try more costly than waiting for the loop to complete (I
guess/hope it's not...) ? Is there a way to have such a piece of information
without having to set up large and tiring profiling techniques ?


Thanks for your help,


Regards,


P.-J.
