There are more nodes like title, description, so how to parse such xml, I am confused about image nodes, I am thinking to use NSMutableArray for this, but still not clear to do code?

Answer 1

use this it work

-(void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict{
    NSLog(@"%@",elementName);
    if([elementName isEqualToString:@"moths"]){
        mytblarray=[[NSMutableArray alloc] init];
    } else if([elementName isEqualToString:@"moth"]){
        tmpdic=[[NSMutableDictionary alloc] init];
    }
    else if([elementName isEqualToString:@"images"]){
        imgArray=[[NSMutableArray alloc] init];
    }

}

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

    if(tmpstr!=nil && [tmpstr retainCount]>0){ [tmpstr release]; tmpstr=nil; }
    tmpstr=[[NSString alloc] initWithString:string];

}

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

    if([elementName isEqualToString:@"moth"]){
        [mytblarray addObject:tmpdic];
        [tmpdic release];
    }if([elementName isEqualToString:@"images"]){
        [tmpdic setValue:imgArray forKey:elementName];
    }
    else if([elementName isEqualToString:@"image"]){
        [imgArray addObject:tmpstr];        
    }
}
