Question

Hey All!
I am trying to use wonderxml (http://code.google.com/p/wonderxml/) to convert my xml into objective-c objects.
It works for a simple case like below…
XML:

<Defn>
   <name>Test1</name>
   <add>my address</add>
</Defn>

Corresponding Class interface:

#import <Foundation/Foundation.h>
@interface Defn: NSObject {
    NSString *name;
    NSString *add;
 }
@property (nonatomic, copy) NSString *name;
@property (nonatomic, copy) NSString *add;

@end

However if i have a XML structure like below, what should i do?

   <Defn>
      <contact>
        <name>Test1</name>
        <add>my address</add>
      </contact>
      <contact>
        <name>Test1</name>
        <add>my address</add>
      </contact>
      .
      .
   </Defn>

What should be my class interface?

Answer 1

In your first example the XML file goes from has the key Defn holding to strings and you ObjC example follows this pattern with an object called Defn, which contains 2 strings.

For your second example, where you have contact holding the strings and then multiple contact’s in Defn, you will probably want to use a similar pattern. Except with your Defn class being renamed to contacts and then the new Defn class holding an array of the contact objects.
So my implementation would be.

contact.h

#import <Foundation/Foundation.h>
@interface contact: NSObject {
    NSString *name;
    NSString *add;
 }
@property (nonatomic, copy) NSString *name;
@property (nonatomic, copy) NSString *add;
@end

Defn.h

#import <Foundation/Foundation.h>
@interface Defn: NSObject {
    NSMutableArray *contacts;
 }
@property (assign) NSMutableArray * contacts;
@end

This might not be the best solution but it follows the XML structure quite well and is a logical step from your original Class interface example.
