I don't find NSScanner all that useful for searching for specific strings in a stream. For example, they don't make a good tokenizer for structured grammars, except in the limited case of a token being a single character. It would be useful if it were extended to allow use of lists of words that had some specific meaning using a dictionary (in an analogous manner to the way it can use character sets), but that's an exercise for another day. Can you not just search for the substrings using the -rangeOfString: family of methods in NSString? --Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
