My code is:

}
-(void)parser:(NSXMLParser *)parser

{
currentElement = elementName;
if ([elementName isEqualToString:#"ValCurs"]) {
itemActive = YES;
currentValute = [[NSMutableString alloc]init];
currentNumCode = [[NSMutableString alloc]init];
currentCharCode = [[NSMutableString alloc]init];
nominal = [[NSMutableString alloc]init];
currentName = [[NSMutableString alloc]init];
currentValue = [[NSMutableString alloc]init];
}
}
-(void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
if (itemActive) {
NSString *fixedString = [string stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
if ([currentElement isEqualToString:#"Valute"])
[currentValute appendString:fixedString];
if ([currentElement isEqualToString:#"NumCode"])
[currentNumCode appendString:fixedString];
if ([currentElement isEqualToString:#"CharCode"])
[currentCharCode appendString:fixedString];
if ([currentElement isEqualToString:#"Nominal"])
[nominal appendString:fixedString];
if ([currentElement isEqualToString:#"Name"])
[currentName appendString:fixedString];
if ([currentElement isEqualToString:#"Value"])
[currentValue appendString:fixedString];
}
}

}
}
-(void)parserDidEndDocument:(NSXMLParser *)parser
{
NSLog(#"%#",articles);
//text.text = (#"%#",currentCharCode);
}
-(void)retrieveXML:(id)sender
{
[parser parse];
}
........
- (void)viewDidLoad {
[super viewDidLoad];
articles = [[NSMutableArray alloc]init];
NSString *myURL = [NSString stringWithFormat:#"http://www.cbr.ru/scripts/XML_daily.asp"];
NSURL *url = [NSURL URLWithString:myURL];
//NSString *urla = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:nil];
parser = [[NSXMLParser alloc]initWithContentsOfURL:url];
parser.delegate = self;
[self createUI];
}
From NSXMLParser reference -NSXMLParserUnknownEncodingError = 31.
May be i need use encoding to NSWindowsCP1251StringEncoding for solve problem ?

Answer 1

NSXMLParserUnknownEncodingError = 31 occurs when document encoding is unknown.
Try this:
NSString *myStr = [[NSString alloc] initWithData:myData encoding:NSWindowsCP1251StringEncoding];
myStr = [myStr stringByReplacingOccurrencesOfString:#"encoding=\"windows-1251\"" withString:#""];
NSData* aData = [myStr dataUsingEncoding:NSUTF8StringEncoding];
NSXMLParser *parser = [[NSXMLParser alloc] initWithData:aData];
