Can anyone let me know how to fetch the [response] value from the below response object
SimpleXMLElement Object (
[MaterialInfo] => SimpleXMLElement Object
    (
        
        [QueryList] => Array
            (
                [0] => SimpleXMLElement Object
                    (
                        [@attributes] => Array
                            (
                                [identity] => EUROHS-0508
                            )
                        [Query] => Array
                            (
                                [0] => SimpleXMLElement Object
                                    (
                                        [@attributes] => Array
                                            (
                                                [statement] => Product Meets EU RoHS Requirements Without Any Exemptions
                                                [response] => false
                                            )
                                    )
