Once you slurp all the A and TXT records in a hash-map or another data
structure of your own with Python, you can iterate over the hash and
print parts or all of it. For example, if you have the hash I printed
in my previous reply, you can print all addresses and text records with
a small bit of code:
: keram...@kobe:/home/keramida$ cat hello.py
: #!/usr/bin/env python
:
: hosts = {'kobe': [('A', '127.0.0.1'),
: ('TXT', '"This is a test"')],
: 'localhost': [('A', '127.0.0.1')]}
:
: for h in sorted(hosts):
: addrs = [x[1] for x in hosts[h] if x[0] == 'A']
: txts = [x[1] for x in hosts[h] if x[0] == 'TXT']
: for a in addrs:
: if len(txts) == 0:
: txts = [""]
: for t in txts:
: print "%-20s %-30s %s" % (a, h, t)
: keram...@kobe:/home/keramida$ python hello.py
: 127.0.0.1 kobe "This is a test"
: 127.0.0.1 localhost
: keram...@kobe:/home/keramida$
Add or remove formatting as you see fit :-)
