Hi Jonh,

Thank you for your reply. 

Yes, I'm traing to escape from Zope-land, to be more clarify I want to
migrate from Plone to PHP Application, which uses MySQL database
engine, so I have to move all data from ZODB to MySQL. I suppose that
python script shouldn`t be so complex. I need just iterate ZODB and
write attributes like "Intro", "Body" of article to file for example.
I need export Plone content hierarchy like


Home
   |
   | - - - Folder 1 (Title, Intro, Body)
   |            | - - - Article (Title, Intro, Body)
   |   
   | - - - Folder 2 (Title, Intro, Body)


Now after your answer, I see that I will be not able to finish this
taks by myself ... 

I'm experienced mostly in C, PHP, also with some backgrounds of CPP
and Java, but I'm totaly new in Python ... 

What do you suggest in this case?
