/**
 * Find node in the set of nodes by the node path and set the value into it.

 * For example:
 *   node and children:
 *     ABC-- A -- A11 -- A111
 *           B -- B11 -- B111
 *           C -- C11 
 *        
 *    NodePath: C/C11/C111
 *    
 *    will create C111 node and return C111 node.
