XML file data as array in Cocoa using XML Parser

Add a xml file in your project

XML File - myxml.xml

<?xml version="1.0" encoding="utf-8" ?>
<data>
<object>
<name>English</name>
<age>24</age>
</object>
<object>
<name>Akram</name>
<age>20</age>
</object>
<object>
<name>John</name>
<age>30</age>
</object>
</data>

Code of file XMLParser.h

#import <UIKit/UIKit.h>
@interface XMLParser : NSObject {
NSMutableString *currentElementValue;
NSMutableArray *records;
NSMutableDictionary *data;
}
-(void)parseDataWithCase;
-(NSMutableArray *)records;
@end

Code of file XMLParser.m

#import "XMLParser.h"
@implementation XMLParser

// initializing array to be obtained after parsing
if(records)
[records removeAllObjects];
else

// xml parsing

import the XMLParser.h class in your class
Call the function parseDataWithCase for parsing xml
and then call the records it return a array of that xml.

XMLParser *xmlParser = [[XMLParser alloc] init];
[xmlParser parseDataWithCase];
myArray = [xmlParser records];
[xmlParser release];

(
{
name = "Amit";
age = 24;
},
{
name = "Akram";
age = 20;
},
{
name = "John";
age = 30;
},
)

You can customize your parse method as you own need

- (void)parser:(NSXMLParser*)parser didEndElement:(NSString*)elementName namespaceURI:(NSString*)namespaceURI qualifiedName:(NSString*)qName
