Parse::Nessus::NBE - use to extract specific data from Nessus NBE files
use Parse::Nessus::NBE;
function(@nessusdata);
function(@nessusdata,$query);
This module is designed to extract information from Nessus NBE files. Functions have been designed to return certain sets of data, such as service banners and OS versions. Other functions have been provided that will return more specific information, such as all IPs listening on a given port or all IPs associated with a specified plugin id.

my @banners = nbanners(@nessusdata);
print @banners;
# returns
IP|service banner
