NSString Backslash escaping

Question

Hi,

I am working on an iPhone OS application that sends an xml request to a webservice. In order to send the request, the xml is added to an NSString. When doing this I have experienced some trouble with quotation marks " and backslashes \ in the xml file, which have required escaping. Is there a complete list of characters that need to be escaped?

Also, is there an accepted way of doing this escaping (ie replacing \ with \\ and " with \") or is it a case of creating a method myself?

Thanks

Answer 1

NSString *escapedString = [unescapedString stringByReplacingOccurrencesOfString:@"\\" withString:@"\\\\"];
escapedString = [escapedString stringByReplacingOccurrencesOfString:@"\"" withString:@"\\\""];

Doesn't fully answer your question, but seems like it might help with the second part...
