can you change your code for this input:

Array
(
    [0] => Array
        (
            [text] => paris
            [nodes] => Array
                (
                    [jacque] => Array
                        (
                            [text] => jacque
                            [nodes] => Array
                                (
                                    [0] => 32.png
                                )
                        )

                    [anis] => Array
                        (
                            [text] => anis
                            [nodes] => Array
                                (
                                    [0] => 5384a97ee9d6b (2).pd
                                )
                        )
                )
        )
