This is to some extent peripheral to your question, but if you have a version of 'dig' that supports the +short option, you'll get a simpler list of data to parse.

For example:

C:\dig>dig www.cnnsi.com +short
64.236.29.106
64.236.29.107
157.166.255.22
157.166.255.23
64.236.22.106
64.236.22.107

C:\dig>nslookup www.cnnsi.com
Server:  ltc1usdc1.us.ceridian.hrs
Address:  10.2.69.11

Non-authoritative answer:
Name:    www.cnnsi.com
Addresses:  64.236.29.106, 64.236.29.107, 157.166.255.22, 157.166.255.
+23
          64.236.22.106, 64.236.22.107
