XML Parser

If XML inside bundle :

NSString *pathStr = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"Mobile_amountDue.xml"]; 

    

    NSData *dataXml = [NSData dataWithContentsOfFile:pathStr];

    

url = [[NSURL alloc] initWithString:pathStr];

    xmlParser = [[NSXMLParser alloc] initWithData:dataXml];

    parser = [[XMLParser alloc] initXMLParser:@"success"];

    [xmlParser setDelegate:parser];

    [xmlParser parse];

if([newsArray count]>0)

{

[newsArray removeAllObjects]; 

}

    newsArray=[parser.parsedXML mutableCopy];

XML read from URL :

#define URL_STRING @"http://www.espncricinfo.com/rss/content/story/feeds/0.xml"// RSS url

#define OUTER_TAG @"item" //Parent Tag

url = [[NSURL alloc] initWithString:URL_STRING];

    xmlParser = [[NSXMLParser alloc] initWithContentsOfURL:url];

    parser = [[XMLParser alloc] initXMLParser:OUTER_TAG];

    [xmlParser parse];
