Check out my NSString category for XMLEntities. There’s methods to decode XML entities (including all HTML character references), encode XML entities, stripping tags and removing newlines and whitespace from a string: – (NSString *)stringByStrippingTags; – (NSString *)stringByDecodingXMLEntities; // Including all HTML character references – (NSString *)stringByEncodingXMLEntities; – (NSString *)stringWithNewLinesAsBRs; – (NSString *)stringByRemovingNewLinesAndWhitespace;
