So, how do I keep a copy hanging around AND kill the mysterious new copy then (which shares the same name as the old one presumably)?


Retain the copy you want to keep around manually:


while([inputString isMatchedByRegex:regexString])
{
	NSAutoreleasePool* pool = [NSAutoreleasePool new];

	range = [inputString rangeOfRegex:regexString];

NSString * newString = [inputString stringByReplacingCharactersInRange:range withString:@""];

	[inputString release]; // release old inputString

	inputString = [newString retain]; // retain new inputString

	[pool drain];
}

WARING: this code not tested for correctness but should give you the idea

The autorelease pool may or may not be necessary here, but given the size of the input may be good defensive coding.
