Encode NSString for XML/HTML

Question

Is there a way to HTML encode a string (NSString) in Objective-C, something along the lines of Server.HtmlEncode in .NET?

Answer 1

the samets's routine forgot the hex digit. Here's the routine I came up with that works:

- (NSString*)convertEntities:(NSString*)string
{

NSString    *returnStr = nil;

    if( string )
    {
        returnStr = [ string stringByReplacingOccurrencesOfString:@"&" withString: @"&"  ];

        returnStr = [ returnStr stringByReplacingOccurrencesOfString:@""" withString:@"\""  ];

        returnStr = [ returnStr stringByReplacingOccurrencesOfString:@"'" withString:@"'"  ];

        returnStr = [ returnStr stringByReplacingOccurrencesOfString:@"9" withString:@"'"  ];

        returnStr = [ returnStr stringByReplacingOccurrencesOfString:@"’" withString:@"'"  ];

        returnStr = [ returnStr stringByReplacingOccurrencesOfString:@"–" withString:@"'"  ];

        returnStr = [ returnStr stringByReplacingOccurrencesOfString:@">" withString:@">"  ];

        returnStr = [ returnStr stringByReplacingOccurrencesOfString:@"<" withString:@"<"  ];

        returnStr = [ [ NSString alloc ] initWithString:returnStr ];
    }

    return returnStr;
}
