parse strings separated by 2 elements

On Mac OS X, in Ojective-C, I wanted to know if anyone could give me some pointers as to how I could parse strings contained between "x" and "y".

My current code only enables me to separate the strings separated by one componennt : 

NSArray * allLines = [theDataObject componentsSeparatedByString:@"word-1"];

Ideally, I would like to isolate the strings contained between @"word-1" and @"word-2".

Could anyone help please? Thanks in advance!

Check the documentation for NSScanner. The methods you want are -scanUpToString:intoString: and -scanString:intoString:

NSString *str = [theDataObject stringByReplacingOccurencesOfString:@"word-2" withString:@"word-1"];
NSArray *allLines = [str componetnsSeperatedByString:@"word-1"];

You don't care whether its word-1 or word-2 as those do not come back in the array anyways.
