It should be easy to walk the string with NSScanner.
Try this as a very primitive starter (no error checking, no warranty, nothing)
- don't use this verbatim in production code, it will work for some simple
cases but not for others (e.g. unmatched brackets etc.).
- (NSString *)throwOutBracketedStuffFrom:(NSString *)aString {
NSScanner *theScanner;
NSString *text = nil;
theScanner = [NSScanner scannerWithString:aString];
while ([theScanner isAtEnd] == NO) {
[theScanner scanUpToString:@( intoString:NULL] ;
[theScanner scanUpToString:@) intoString:text] ;
aString = [aString stringByReplacingOccurrencesOfString:[NSString
stringWithFormat:@%@%@, text, @)] withString:@];
}
return aString;
}
Read up on NSScanner.
Or try RegExKitLite, which I
prefer.___

It's slightly overkill for the situation, but CoreParse (http://www.github.org/beelsebob) will deal with nested parens quite happily.___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

For a minimal solution, you could just use rangeOfString:options: to find the parentheses. Depends on whether you might have multiple pairs, whether you might have parentheses inside pairs and how you want to treat that, whether you also want to remove the whitespace adjacent to but outside the parentheses, etc... First, define your problem. :) ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

I always end up taking the ghetto route and just using -rangeOfSubstring: and substringWithRange: for stuff like this. It would probably be cleaner to use NSScanner though, at least until NSRegularExpression goes mainstream. —Jens smime.p7s Description: S/MIME cryptographic signature ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
