Any Method to remove comment characters from JSON response in XCode?

Question

I am new to JSON. Are there any methods in JSON parser to remove the comment characters from a response.

Eg. //{"response":"success".......

its SBJson for iPhone. from http://code.google.com/p/json-framework

Answer 1

The JSON grammar doesn't allow comments. That doesn't answer your question obviously, but I suspect you'll have to do some string manipulation and replace all those comment characters with empty strings and parse it with the JSON library only after doing so.

Answer 2

Can you post some more code? What part of the JSON string do you need?

Just don't parse the response into your dictionary/object/whatever...

Answer 3

The JSON parsers are very finicky about what is at the start of a JSON block to parse - they DO NOT like characters other than "{" at the start (at least that's what I found with TouchJSON, and it sounds like your case with SBJson is similar).

So just take your string and eliminate any characters before the opening "{", then you can parse:

NSRange startJSONRange = [myJSONString rangeOfString:@"{"];
startJSONRange.length = myJSONString.length - startJSONRange.location;
NSString *correctJSONString = [myJSONString substringWithRange:startJSONRange];

// parse correctJSONString

That will work, but the REAL fix is to tell whoever is sending you JSON to cut out the nonsense and send real JSON.
