[iPhone] Any built in way to convert HTML entities to Unicode?

Question

I have a string with contents something like:
"© 2008"
Is there some method that I can't seem to find that will convert this to:
"© 2008"
Basically is there something built in to convert all of the '&xxx;' HTML entities to their Unicode counterpart? I can write my own code to do it but I want to check here first.
Thanks.

I had the same problem and did only find a semi built in solution using NSXMLParser
@interface MREntitiesConverter : NSObject {
NSMutableString* resultString;
@property (nonatomic, retain) NSMutableString* resultString;
- (NSString)convertEntiesInString:(NSString)s;
@end
@implementation MREntitiesConverter
@synthesize resultString;
- (id)init
if([super init]) {
resultString = [[NSMutableString alloc] init];
return self;
- (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)s {
[self.resultString appendString:s];
- (NSString)convertEntiesInString:(NSString)s {
if(s == nil) {
NSLog(@"ERROR : Parameter string is nil");
NSString* xmlStr = [NSString stringWithFormat:@"<d>%@</d>", s];
NSData *data = [xmlStr dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];
NSXMLParser* xmlParse = [[NSXMLParser alloc] initWithData:data];
[xmlParse setDelegate:self];
[xmlParse parse];
NSString* returnStr = [[NSString alloc] initWithFormat:@"%@",resultString];
return returnStr;
- (void)dealloc {
[resultString release];
[super dealloc];
@end
In Cocoa (Core Foundation) there is
NSString* sI = (NSString*)CFXMLCreateStringByUnescapingEntities(NULL, (CFStringRef)s, NULL);
but that does not (yet?) exist on the IPhone (2.01)
