[Zope] Traversal Issue (brain fart)

[Richard Shebora]

Hi all,

I have a python script that reads a file in from LocalFS
on the hard drive.  I am parsing it and creating
objects in a tree structure based on the parsed data.
I have found various examples that have gotten me
this far.  I cannot seem to get a grip on how to
cleanly move around the ZODB in Zope to create the
Folders, Sub Folders, and then add properties to
specific folders.  At the last step in my program
which adds a final set of folders and will need to
add properties to them, I seem to completely loose
the "Context" of the current folder.

Any pointers or examples to clarify how to
programmatically specify where my objects are
created would be much appreciated.

I am sure it is much simpler than I have made it.

Thanks,
Richard
