WonderXML is an extension of GData XML Node class (Gdata Objective C library) which is able to Parse xml string to objects dynamicly, and convert objects back to xml string.

How to set up

• iPhone applications need these build settings in the project or target:

Header Search Paths: /usr/include/libxml2

Other Linker Flags: -lxml2

• Drag all files in wonderxml group into your project.

• See a simple test in the app delegate (output is in console).

• Enjoy...

How to use it

• The User Class header file

#import <Foundation/Foundation.h>

@interface User : NSObject {
    NSString *billingEmailAddress;
    NSString *billingSchedule;
    NSString *brandID;
    Boolean changePassword;
    NSString *expiration;
    NSString *lastAddress;
    NSString *lastLogIn;
    NSString *password;
    NSString *preferences;
    NSNumber *profileID;
    NSString *settings;
    NSNumber *userID;
    NSString *username;
}

@property (nonatomic, assign) Boolean changePassword;
@property (nonatomic, copy) NSString *expiration;
@property (nonatomic, copy) NSString *lastAddress;
@property (nonatomic, copy) NSString *lastLogIn;
@property (nonatomic, copy) NSString *password;
@property (nonatomic, copy) NSString *preferences;
@property (nonatomic, copy) NSNumber *profileID;
@property (nonatomic, copy) NSString *settings;
@property (nonatomic, retain) NSNumber *userID;
@property (nonatomic, copy) NSString *username;
@property (nonatomic, copy) NSString *billingSchedule;
@property (nonatomic, copy) NSString *brandID;
@property (nonatomic, copy) NSString *billingEmailAddress;
@end

• The User Class .m file

#import "User.h"


@implementation User

@synthesize changePassword;
@synthesize expiration;
@synthesize lastAddress;
@synthesize lastLogIn;
@synthesize password;
@synthesize preferences;
@synthesize profileID;
@synthesize settings;
@synthesize userID;
@synthesize username;
@synthesize billingSchedule;
@synthesize brandID;
@synthesize billingEmailAddress;

- (void)dealloc
{
	[billingEmailAddress release];
	billingEmailAddress = nil;
	[billingSchedule release];
	billingSchedule = nil;
	[brandID release];
	brandID = nil;
	[expiration release];
	expiration = nil;
	[lastAddress release];
	lastAddress = nil;
	[lastLogIn release];
	lastLogIn = nil;
	[password release];
	password = nil;
	[preferences release];
	preferences = nil;
	[settings release];
	settings = nil;
	[username release];
	username = nil;
	
	[userID release];
	
	[profileID release];

	[super dealloc];
}


@end

• The User xml string

NSString *testUserString = @"<?xml version=\"1.0\" encoding=\"UTF-8\" standalone=\"yes\"?>
<User xmlns:=\"http://bluepinme.com\"><billingSchedule>00 00 08 * * *</billingSchedule>
<brandID>9908315</brandID><changePassword>false</changePassword>
<expiration>1970-01-01T00:00:00Z</expiration><lastLogIn>1970-01-01T00:00:00Z</lastLogIn>
<password>bbbb</password><profileID>1968515</profileID><userID>1831917</userID>
<username>fffffff</username></User>";

• Sending XmlParser fromXml message

XmlParser *parser = [[[XmlParser alloc] init] autorelease];
User *user = [[[User alloc] init] autorelease];
	
NSMutableArray *userArray = [parser fromXml:testUserString withObject:user];


NSLog(@"userArray :: %@", userArray); 

• "userArray" will only contain a user object since we only passed in a single user node
• Convert user object to its xml string representation by sending XmlParser toXml message

user = [userArray objectAtIndex:0];

//object to xml string
NSNumberFormatter * numberFomatter = [[[NSNumberFormatter alloc] init] autorelease];
[numberFomatter setNumberStyle:NSNumberFormatterDecimalStyle];
NSNumber * aNumber = [numberFomatter numberFromString:@"123456"];
	
user.userID = aNumber;
user.username = @"test";
	
NSString *userString = [parser toXml:user andTag:@"User" inNameSpace:@"http://bluepinme.com"];

NSLog(@"userString :: %@", userString);

• The output looks like

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<User xmlns="http://bluepinme.com"><username>test</username><brandID>9908315</brandID><billingSchedule>00 00 08 * * *</billingSchedule>
<userID>123456</userID><lastLogIn>1970-01-01T00:00:00Z</lastLogIn><changePassword>0</changePassword><password>bbbb</password><expiration>1970-01-01T00:00:00Z</expiration>
<profileID>1968515</profileID></User>
