I have a firewall that has the follwoing type of dataset:

config firewall policy
    edit 1
        set srcintf "internal"
        set dstintf "wan1"
            set srcaddr "all"
            set dstaddr "all"
        set action accept
        set schedule "always"
            set service "ANY"
        set nat enable
    next
    edit 2
        set srcintf "internal"
        set dstintf "VPN-AU"
            set srcaddr "all"
            set dstaddr "all"
        set action accept
        set schedule "always"
            set service "ANY"
    next
    edit 3
        set srcintf "VPN-AU"
        set dstintf "internal"
            set srcaddr "all"
            set dstaddr "all"
        set action accept
        set schedule "always"
            set service "ANY"
    next
end

I would like to pull out information and assign to variables (or a datastructure) and print the whole thing out in CSV. I don't need most of it just how to set multipline to use config as beginning, and 'end' as the end. I then want to use perl memory to slurp up the relevant info. So I would like to see:

Policy,srcif,
  2,internal

Etc. once I am done. I know how to write the regexen, just not to do multiline. Even better would be a decent data structure to store all of the mess. But I am CS illiterate and not too good at data structures. Hence this post.
