I have some difficulties to understand how to use NSXMLParser despite all the tutos I've watched...I have the following XML file with for example :\[code\]<rss><channel><title>The Title</title><link>A URL</link><language>English</language><item> <name>John</name> <title>John4034</title> <city>LA</city> <country>USA</country></item>....<item> <name>Marc</name> <title>Marc2942</title> <city>London</city> <country>England</country></item></channel></rss>\[/code\]I aim to stock all the items in a NSMutableArray of Item. My class Item has 4 NSString (name, title, city, country).Here is my XMLParser.m file :\[code\]- (id) loadXMLbyURL : (NSString *) urlString{ items = [[NSMutableArray alloc] init]; NSURL *url = [NSURL URLWithString:urlString]; NSData *data = http://stackoverflow.com/questions/10777116/[NSData dataWithContentsOfURL:url]; parser = [[NSXMLParser alloc] initWithData:data]; parser.delegate = self; [parser parse]; return self;}- (void) parser
NSXMLParser *)parser foundCharactersNSString *)string{ currentNodeContent = (NSMutableString *) [string stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];}- (void) parserNSXMLParser *)parser didStartElementNSString *)elementName namespaceURINSString *)namespaceURI qualifiedNameNSString *)qName attributesNSDictionary *)attributeDict{ if([elementName isEqualToString

- I've no data in my items properties... everything is (null) when I try to print it in the log.
