Get specific value from NSMutableArray

Question

I'm parsing an XML and saving result to NSMutableArray. When I do NSLog,

NSLog(@"Data : %@",_data);

I'm getting

Data : (
        {
        SessionToken = 9e72dd029e0e8268380b919356881935;
    }
)

I only want 9e72dd029e0e8268380b919356881935 from the array. What is the best solution to achieve this?

EDIT : There will be only one SessionToken at a time.

Your data is an array of dictionary. You just need to use "SessionToken" key and you will get the value. — Anupdas

An NSDictionary can only map one object to one instance of a key. — Tim

@jack My question was if _data array contain more than one sessionToken at a time? — Anupdas

You can try this code :

for (NSDictionary *data1 in _data) {
    NSlog("session token %@",[data1 objectForKey:@"SessionToken"]);//Other wise add into another array which contain session token.. only..
}

Since there will be only one session at a time.

NSDictionary *session = [_data lastObject];
NSString *sessionToken = session[@"SessionToken"];

OR with literals

NSString *sessionToken = _data[0][@"SessionToken"];

@Viral As per the OP, there will be only one object in the array. If I don't use literals i always use lastObject as it will not crash if there are no objects. The second alternative was to show how this can be done with literals thats it.

if ([_data count]) {
    NSDictionary *dic = [_data objectAtIndex:0];
    NSLog(@"Data : %@",[dic objectForKey:@"SessionToken"]);
}

You could potentially expand this answer / explain it a bit more.
