Quite right. Is worse than you can possibly iagine at leats here in te
UK, where addresses can be as little as 2 lines long or up to 6..
So
10 Wonkers place, LONDON EC3 7QY is a typical TOWN address
Out in the sticks you might get
Apartment 4b, the Old Town House, Shire Lane, Recketts Green, Nr
Stonehouse, Gloucestershire GL13 6AH
And if that comes at you without commas, god help you.
I have spent DAYS taking name/address fields and parsing them *manually*
into structured tables...
