Deserialize objective-c binary NSMutableArray in python -

i'm putting google app engine webapp in python , i'm seeding database iphone app (sqlite).

i'm having bit of difficult on 3 fields defined blob fields , have binary serialized objects in them. (typically start out "bplist" i'm assuming it's binary serialized property list - ones interested in contain serialized nsmutablearray's within them.)

i'm suspecting 2 choices a) see how amenable binary format regex style scraping out of values (they text) b) write quick ios app, open database, export data better format

any other ideas, suggestions on best route, or (fingers cross) pointers sort of great python egg solves problems.

below have encluded sample , tried format reasonably medium - out of bottom need extract (anonymized actual data)

street = "1111 address ln #2004" street2 = "" city = "dallas" state = "tx" zip = "75243" country = "" type = "" 

here's data looks typical entry: http://dl.dropbox.com/u/6649380/serializedobject.txt

if planning on running script on mac, can use plutil command convert more parseable xml format:

plutil -convert xml1 -o outfile infile 

to have output go stdout, use - output file. if leave -o option out, output overwrite input file. if prefer, use json format instead of xml1 json formatted output.
