how to fetch data from xml parsing - ios

Question

I am trying to parse data from xml parsing but it could not show anything ..
-(void)viewDidLoad {
[super viewDidLoad];
self.mdata=[[NSMutableData alloc]init];
marr=[[NSMutableArray alloc]init];
mwebcall =[[NSMutableArray alloc]init];
NSString *urlstr=#"http://www.espncricinfo.com/rss/content/story/feeds/6.xml";
NSURL *url1 = [NSURL URLWithString:urlstr];
NSURLRequest *urlrequest=[[NSURLRequest alloc]initWithURL:url1 ];
con = [[NSURLConnection alloc]initWithRequest:urlrequest delegate:self];
[con start];
}
// Do any additional setup after loading the view, typically from a nib.
//#pragma mark-xmlmethods
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[mdata appendData:data];
}
-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
}
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
self.xmlparse=[[NSXMLParser alloc]initWithData:mdata];
self.xmlparse .delegate=self ;
[self.xmlparse parse];
}
-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
NSLog(#"%#",error);
}
-(void)parserDidStartDocument:(NSXMLParser *)parser{
}
-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
if ([elementName isEqualToString:#"item"])
{
str=#"item";
}
else if ([elementName isEqualToString:#"title"])
{
str=#"title";
}
}
-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
if ([str isEqualToString:#"item"])
{
str1=#"";
str1=[str1 stringByAppendingString:string];`enter code here`
}
if ([str isEqualToString:#"title"])
{
str1=#"";
str1=[str1 stringByAppendingString:string];
NSLog(#"%#",str1);
}`enter code here`
}
-(void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
if ([str isEqualToString:#"item"])
{
[mwebcall addObject:str1];
NSLog(#"%#",str1);
}
if ([str isEqualToString:#"title"])
{
[mwebcall addObject:str1];
NSLog(#"%#",str1);
}
}

Use this GitHub library.
OR
NSString *url=#"http://www.lancers.jp/work";
NSData *data=[NSData dataWithContentsOfURL:[NSURL URLWithString:url]];
NSDictionary *dict=[XMLParser dictionaryForXMLData:data error:nil];
NSLog(#"%#",[dict description]);
Use this code and create the following files
