Zone stats

Hi,
I'm writing some software to be able to read information from a Zone
file. I am a legally authorised Secondary Authoritative Nameserver for a
number of domains or rather zone files, eg. EDU.ZA (and others). Is
there an easy way to:-
1) Count how many delegated domains there are (Names with NS records)
2) Extract the above Names - so I can look for changes (Added/Deleted names)
3) find out how many unique names have DS records (I can DIG I suppose)
I'd also like to spot broken stuff (named-checkzone ?)
So the zones (such as EDU.ZA) contain the domain name of the entity
(whois.edu.za) along with the Nameserver records and in this case, a DS
record. e.g... "whois.edu.za" looks like....
whois NS control.vweb.co.za.
NS secdns1.posix.co.za.
NS secdns2.posix.co.za.
NS secdns3.posix.co.za.
DS 27300 13 2
8ED21DB407F6AC3E6EA757AE566953C1BBADD8B652BE4C7C0744B1D7 9DF42894
DS 17837 13 2
36FD5B19450B672988AE507FB7D2F948ED1E889546C6E16554C7EAF9 CE9C3FEA
One hindrance is that journal files are present - so it is not just the
zone file but the zone.jnl file as well.
Some African ccTLDs have everything in one zone e.g. their COM, EDU, GOV
- etc. In South Africa, these are all separate zones, making life
somewhat easier.
I'd hate to re-invent software that already exists.
The primary purpose is to pull in data into an (ICANN requested) African
DNS Observatory.
