 If you want to access to deeper elements like `admin` for example, just chain :
 ```swift
 let blogAdmin: String! = parser["users"]["admin"].stringValue

 To iterate over **all** children of an element, just use the `for in` classic syntax :

 Until now, we always retrieved existing tags but what would happen if a tag doesn't exist ? Fortunaly for us, CheatyXML manages this case. Let's take an example :
 ```swift
 let articleDate: String! = parser["article", 0]["infos"]["date"].stringValue
-println(articleDate) // 2015-03-15 15:42:42
+print(articleDate) // 2015-03-15 15:42:42
 let articleDateFail: String! = parser["articles", 0]["infos"]["date"].string // I intentionally add an 's' to 'article'
-println(articleDateFail) // nil
+print(articleDateFail) // nil
 ```
 > ###### Note
 If you have doubts on your chain, keep in mind that using `.string` is safer than using `.stringValue`. In the previous example, using `.stringValue` on `articleDateFail` will result in your application to crash.
