The AddressBook example in bazar show the possibility to store datas but it creates a new xml everytime, so the problem is a bit different.

The example has everything you need to do what you want. You can skip the FileSel dialog part and insert a fixed file name so that it doesn't "create a new xml everytime" (if I got it right).

If I do it, XML is good for storage and transportation of information beyond your application. Within your application, you should be better off to store it in a, eg sorted Vector, for better performance.

so:
1. program start, read(parse) XML database, and store car info in a more accessible way;

2. do add/edit/delete as you do in any other data manipulation application. XML is not relevant here

3. when close or explicit save requested, check if data is changed, if yes, save to XML.

you can already do 1 and 3 with reference to AddressXML, so just figure out how you should do 2.
