Answer 1

You can use below code to find your "id" value in XML parsing method,

- (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName 
  namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName 
    attributes:(NSDictionary *)attributeDict {

    if([elementName isEqualToString:@"p"])
    {

     int idValue = [[attributeDict objectForKey:@"id"] intValue];

     NSLog(@"Reading id value :%d", idValue);
    }

}

Answer 2

In your (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDictmethod, the attributeDict argument contains all the attributes. For example, to access the 'id' attribute, simply call [attributeDict objectForKey:@"id"].
