Hi, 
You can make a XML-RPC Call on a python function called for exemple get_orders(self)

in this function you search for all orders you want. ( you may want only orders that satisfy some conditions ). 

then if you have a positive result, you loop on them like this :

for order in orders :

   adrress = self._get_order_infos(order)

    print order, adress

return True

Then in get_order_infos(self, order):

     // if u only want  shipping address: 
    return order.shipping_addre_field  // you may need to check the relation between the models to get the adress

    // if you need to get other infos, you better create a list to return.

Hope this helps.
