I have a primary stream consisting of records that look like this: MX-record-name mail-server1 mail-server2 ...
I have a secondary stream consisting of all the unique mail-serverN names extracted from the primary stream for which A-records exist. I want to keep only those primary stream records for which ALL the mail-serverN names listed on that record are found in the secondary stream. I can't quite figure out how to approach this. As an example, say I have: d01mll96 d01mll96.ibm.com d01mc097.ibm.com d23m0072 d23m0072.ibm.com d23ml072.ibm.com on the primary stream and d01mll96.ibm.com d01mc097.ibm.com d23ml072.ibm.com on the secondary, I'd want just d01mll96 d01mll96.ibm.com d01mc097.ibm.com on the output (since d23m0072.ibm.com is not found on the secondary stream). Ideas? -- bc
