I figured it out
NSString *s = [NSString stringWithContentsOfURL:[NSURL URLWithString:@"http://www.example.com/file.html
"]];
NSRange f, l;

f = [s rangeOfString:@" title=\"Title\">"];
if (f.location == NSNotFound) NSLog(@"failed");
s = [s substringFromIndex:f.location + f.length];

l = [s rangeOfString:@"</a>"];
if (l.location == NSNotFound) NSLog(@"failed");
s = [s substringWithRange:NSMakeRange(0, l.location)];
