generating a tree-like structure

[Thorsten Kampe]

Hi,

This is a fairly general question: is there some kind of module or
framework that allows building a tree like structure from certain kind
of data?

To be specific: I have a program that dumps the content of a LDAP
directory including all properties and values and groups the result
from the LDAP search by objClass.

Now I was thinking: would it be possible to generate from the totally
unordered output that the LDAP server gives me, a tree like
representation that displays the hierarchy (omitting the values or
even properties if necessary)?

It should be a textual representation of what you see in GUI programs
like "LDAP Administrator" but the output should be represented like
the "tree" program in Linux or Windows "tree.com".

Any ideas appreciated...

I think you might be able to use ElementTree. The website for the
module claims it can be used for hierarchical data structures:
http://effbot.org/zone/element-index.htm

Did you look at any of the Python LDAP tools? They might be useful
too. See some of the links below:
http://linuxjournal.com/article/6988
http://aspn.activestate.com/ASPN/Coo.../Recipe/303336

Hopefully they'll give some guidance. I've not used LDAP myself as of
yet.

I already have the LDAP output part working - with python-ldap under
Cygwin - and I generate HMTL output with markup.py. Pretty simple. But
a tree structure output would be even prettier...

I would probably generate a DOT file to get a 2D visualization. DOT is part of
Graphviz (graphviz.org), and there are quite a few graphviz front-ends
available in Python to make DOT generation easier (pydot, yapgvb, and probably
a few others).
