How to get first item of Varien_Data_Tree_Node_Collection

Question

I am not being able to figure out how to get the first item in this type of collection: Varien_Data_Tree_Node_Collection

without knowing the key, is this possible?

Answer 1

Class Varien_Data_Tree_Node_Collection implements ArrayAccess. Try to use

 reset($varienCollection);  //to reset the internal array pointer
 $firstElement = current($varienCollection);
