Hi,
I'm using web-kit for loading an svg map in my application, I want to 
store the map data in memory for redisplay with some mods (like 
changing the colors at given population data etc.).
I'm thinking to trasform svg data in xml plain data and managing an 
nsxmldocument for storing changes but I don't know how render the web-
view with xml
Perhaps I shouldn't convert data to xml but working directly with svg 
format, how can I store the whole file in memory for editing?
I'm a rookie programmer I'm not sure my question has sense :)
Bye
