dynamic zone file "style"

It's possible to use TSIG keys to match views. So you could do the zone transfers with different TSIG keys and get different versions of the same zone.

I understand your point. But for the script, I'll need the content of all my zones in all views. Zone transfers won't be very efficient for that.
Until now I have experimented with the "-j" option from named-compilezone to take care of the journals. Though, I'm not sure this is much more efficient. 
Another option I evaluated was "rndc sync", but it isn't available on bind 9.8 But your reply made me think of yet another solution. "rndc dumpdb -zones" gives me the latest content of all zones of all views in a single file. And, luckily, it uses the "full" style :) So this should be fine for me.

But before I try to re-invent the wheel:
Does anyone know if there is already a parser for multiple zone_files/zone_dumps/zone_transfers? I'm trying to filter all DNS records that are related to a given host/ip?
