parsing xml file with spanish (non UTF-8 format) - iphone

Question

I need to parse xml files in spanish (were I don't have control over how are being generated). the parsing part works just fine but the problem is when the xml file has special characters for example:
Espectáculos
when is parse I get this:
áculos
I'm using CocoaXMLParser. any of you knows how can this been handle ?
this is my code:
-(void)getRss
{
NSString *urlString=#"http://mysite.com/content.xml";
NSURL *url=[NSURL URLWithString:urlString];
NSURLRequest *rssRequest=[NSURLRequest requestWithURL:url];
self.contentConnection=[[NSURLConnection alloc]initWithRequest:rssRequest delegate:self startImmediately:YES];
}
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
self.dataResponse = [NSMutableData data];
NSLog(#"didReceiveResponse");
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
[_dataResponse appendData:data];
NSLog(#"didReceiveData");
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
NSLog(#"didFailWithError");
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
NSLog(#"connectionDidFinishLoading ");
[self parseContent];
}
-(void)parseContent
{
NSString *response = [[NSString alloc] initWithData:_dataResponse encoding:NSUTF8StringEncoding];
NSLog(#"data received %#", response);
NSLog(#"parse content ");
NSXMLParser *parser = [[NSXMLParser alloc] initWithData:_dataResponse];
parser.delegate = self;
[parser parse];
}
- (void) parser:(NSXMLParser *)parser foundCharacters:(NSString *)string
{
self.currentNodeContent = (NSMutableString *) [string stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]];
}
- (void) parser:(NSXMLParser *)parser didStartElement:(NSString *)elementname namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict
{
if ([elementname isEqualToString:#"categoriaNoticias"])
{
self.validXML=YES;
NSLog(#"es xml valido");
}
else
{
self.validXML=YES;
}
}
- (void) parser:(NSXMLParser *)parser didEndElement:(NSString *)elementname namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName
{
if (_validXML) {
if ([elementname isEqualToString:#"titulo"])
{
NSString *string=_currentNodeContent;
NSLog(#"titulo %#", string);
}
if ([elementname isEqualToString:#"link"])
{
NSLog(#"titulo %#", _currentNodeContent);
}
}
}
I'll really appreciate any pointers

Assuming that your XML file is encoded in Latin-1 (ISO-8859-1), you fix the XML file on the fly:
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response {
const char* xmlDecl = "<?xml version=\"1.0\" encoding=\"ISO-8859-1\" ?>\r\n";
self.dataResponse = [NSMutableData data];
[self.dataResponse appendBytes: xmlDecl length: strlen(xmlDecl)];
}
Please check what the effective encoding is and adapt the accordingly if needed.
