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)];

So here is what I am trying to do in this html page on line there
are to points which stays the same and in the middle of the points
is what I need here is an example.
<a href="example.com" title="Ttitle">text I want</a>
so I want to get the text in the middle of points title="Ttitle">
and </a>
Here is what I tried and did not work
NSString *url = [NSString stringWithContentsOfURL:[NSURL
URLWithString:@"http://www.example.com/file.html";]];
NSString *s = url;
NSRange f, l;
f = [url rangeOfString:@"{\" title=\"Ttitle\">"];
Maybe it failed because your source string ("url", which is not a
URL, BTW) does NOT have a { character in it? (I'm thinking perhaps
you accidently added the { when you typed the ".)
