.sec parsing grammar

[sony94]

Hi

I'm new to parsing and I want to write a .sec LL parser.

This is the grammar I have so far:

tile            ->    num-num: tile_tail

tile_tail       ->    ProtectionZone, tile_tail
                ->    Refresh, tile_tail
                ->    cont

cont            ->    Content={num cont_tail

cont_tail       ->    , num cont_tail
                ->    , num key=num cont_tail
                ->    , num cont cont_tail
                ->    }

key             ->    Amount
                ->    Charges
                ->    PoolLiquidType
                ->    RemainingExpireTime  

num             ->    [0-9]+

improvements? corrections?

bump!
I can see that the first production of cont_tail is troublesome
