Extracting data from zone files

Last Modified: 2010-04-21
I'm looking for a solution to the following problem...
I need a 3 column file of the domains like this
mydomain1.tld ns1.mywebserver.tld.
mydomain2.tld ns1.mywebserver.tld.
mydomain3.tld ns1.myotherserver.tld.

I'm  in  the named zone root directory & grep returns a list of zone files like this..
#grep -lr 'SOA' *

I can get the data into individual lists but not combined...
eg the domain names using..
# grep -r 'SOA' *|grep 'zones'|cut -d ':' -f 1|cut -d '/' -f 3
the dns server..
# cat `grep -r 'SOA' *|grep 'zones'|cut -d ':' -f 1`|grep '*'|awk '{print $5}
the IP of the website
cat `grep -r 'SOA' *|grep 'zones'|cut -d ':' -f 1`|grep 'SOA'|awk '{print $4}'

Here is a sample zone file
# cat /hsphere/local/var/named/zones16/5/maverick.tld
$ORIGIN tld.
maverick   86400   IN      NS      ns2.myserver.tld.    ;Cl=3
        86400   IN      NS      ns1.myserver.tld.    ;Cl=3
        86400   IN      SOA     ns2.myserver.tld. nocadmin.myserver.tld. (
                2003123101 10800 3600 604800 86400 )    ;Cl=3
        86400   IN      A  ;Cl=3
        86400   IN      MX      10 pop3.maverick.tld.        ;Cl=3
$ORIGIN maverick.tld.
mail    86400   IN      CNAME  10  maverick.tld.   ;Cl=3
*       86400   IN      A  ;Cl=3

Thanks everyone
