I'm parsing a large XML file using NSXMLParser (OS X) and part of the nested structure is similar to this:
<Person> ... ... <PhoneNumbers> <PhoneNumber> <PhoneNumberType>Home</PhoneNumberType> <PhoneNumberValue>123-555-1234</PhoneNumberValue> </PhoneNumber> <PhoneNumber> <PhoneNumberType>Work</PhoneNumberType> <PhoneNumberValue>345-555-6612</PhoneNumberValue> </PhoneNumber> <PhoneNumber> <PhoneNumberType>Mobile</PhoneNumberType> <PhoneNumberValue>222-555-8901</PhoneNumberValue> </PhoneNumber> </PhoneNumbers> ... ... </Person> In advance I don't know how many phonenumbers there will be, there could be none, or more than three, and they also may have a different <PhoneNumberType> (eg 'Second Home'). The obvious thing to do I guess, is just everytime the parser reaches <PhoneNumbers>, I create an array, and every time the parser reaches <PhoneNumber> I create a dictionary, fill it with the type and number and add that to the array when </PhoneNumber> is reached. However, the data read with the parser needs to end up in my Core Data model. Obviously I already created a Person entity, but how do I add the phone numbers to it? Create a PhoneNumber entity with two attributes? Or stuff the PhoneNumbers array in an NSData object, and make that an attribute of the Person entity, and pull out the data when needed? I see the advantage of the former, in case I want to find out which Persons share a PhoneNumber (or Address, Car, etc). I guess my question is, should I make my CoreData model as nested as my XML file is, with lots of small entities? Furthermore, converting an XML file into strings, arrays and dictionaries, and then converting it back to Entities which are stored in an XML structure in the store seems over complicated to me. Any thoughts on that? - Koen. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
