Now this get a bit more complicated...
eksample-data I'm processing:
"76543";"4";"000X¤¤¤KOST998765;XXXX¤¤ORG
98765;XXXX¤NONSET876545;XXXX¤SIGNAL76543;";"Some information";"Even more
information";

This is excerpt from python-script:
---------------------------------------------------------
        line = oufil.readline()
        if not line:
                break
        fields = p.parse(line)		# this parses the 5 main fields
        hierarki = p.parse(fields[2])   # this parses the N fields in of
fields[2] which can be everything from 1 to 4 fields
					
        if not fields:
        	continue
----------------------------------------------------------

What I'm struggeling for is this hash-table.. 
12345	Parent1-name
23456	Parent2-name, Parent1-name
34567	Parent3-name, Parent2-name, Parent3-name
45678	Parent4-name, Parent3-name, Parent2-name, Parent1-name

the csv-data is sorted before starting the script...

>From the hash-table I'm going to build ldap-files (ldif) for importing
into an ldap-server
typically:
dn= ou=Parent4-name, ou=Parent3-name, ou=Parent2-name,
ou=Parent1-name,dc=no
    objectClass: top
    objectClass: organizationalunit
ou: Parent4-name

(though I have to build ou's for those with no parent(parent1) first,
then parent2 and so on)

How do you suggest the design of such a system (even in pseudo-code)
