This class is used to store data:

#import <Foundation/Foundation.h>

@interface Transaction : NSObject
{
NSString *strDate;
NSString *strAmount;
NSString *strCard;
}
@property (nonatomic, retain) NSString *strDate;
@property (nonatomic, retain) NSString *strAmount;
@property (nonatomic, retain) NSString *strCard;
@end


#import "Transaction.h"


@implementation Transaction

@synthesize strDate;
@synthesize strAmount;
@synthesize strCard;

-(id)init
{
self=[super init];
return self;
}


@end


Following class will be used to parse the data:
