How to Load External XML in xCode

1. Create a different class for this. Lets suppose XMLParse

Code for XMLParse.h is:

#import <Foundation/Foundation.h>

@interface XMLParse : NSObject <NSXMLParserDelegate>

{

    NSMutableString *currentElementValue;

    NSMutableArray *users;

}

@property(nonatomic, retain) NSMutableArray *users;

- (XMLParse *) initXMLParser;

- (void) loadDataFromXML;

- (void) doParse:(NSData *)data;

@end

Code for XMLParse.m is:

#import "XMLParse.h"

@implementation XMLParse

@synthesize users;

- (XMLParse *) initXMLParser

{

    users = [[NSMutableArray alloc] init];

    return self;

}

//XMLParsing

-(void) loadDataFromXML

{

    NSString *path=[[NSBundle mainBundle] pathForResource:@"UserInfo" ofType:@"xml"];

    NSData *data = [NSData dataWithContentsOfFile:path];

    [self doParse:data];

}

- (void) doParse:(NSData *)data

{

    NSXMLParser *nsXMLParse = [[NSXMLParser alloc] initWithData:data];

    [nsXMLParse setDelegate:self];

    [nsXMLParse parse];

}

-(void) parser:(NSXMLParser *)parser

didStartElement:(NSString *)elementName

  namespaceURI:(NSString *)namespaceURI

 qualifiedName:(NSString *)qName

    attributes:(NSDictionary *)attributeDict

{

    printf("User Info %s", [elementName UTF8String]);

    

    if([elementName isEqualToString:@"User"])

    {

        //Get the attribute value

        printf("XML - %s", [[attributeDict objectForKey:@"uname"] UTF8String]);

    }

}

-(void) parser:(NSXMLParser *)parser

 didEndElement:(NSString *)elementName

  namespaceURI:(NSString *)namespaceURI

 qualifiedName:(NSString *)qName

{

    printf("\nEnd ");

    if ([elementName isEqualToString:@"Users"]) {

        // We reached the end of the XML document

        return;

    }

    if ([elementName isEqualToString:@"user"]) {

        

    } else {

        

    }

}

- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string {

    if (!currentElementValue) {

        // init the ad hoc string with the value

        currentElementValue = [[NSMutableString alloc] initWithString:string];

    } else {

        // append value to the ad hoc string

        [currentElementValue appendString:string];

    }

    printf("Processing value for : %s", [string UTF8String]);

}

@end

How to call 

#import "XMLParse.h"

@interface ViewController ()

@property (nonatomic) XMLParse *parser;

@end

@implementation ViewController

- (void)viewDidLoad

{

    [super viewDidLoad];

    self.parser = [[XMLParse alloc] initXMLParser];

    [self.parser loadDataFromXML];

}
