Which language for sorting scan results?

Hello list,

I was hoping to get a discussion going regarding sorting the results of the 
scans being conducted into a more usable format.

I plan to run nmap, retina, and nessus scans and sort them into a single report 
sorted by IP to determine which vulnerabilities are on each device. Which 
programming language would be best for performing the compilation? I'm 
currnetly checking into Perl, but was looking at XML as well.

Any recommendations and dicussion is greatly appreciated.

Thanks.
