read xml simple element objects into an array

Question

i have read an xml file but it returns like this

Array
(
[0] => Array
    (
        [0] => SimpleXMLElement Object
            (
                [0] => 94351
            )
    )

[1] => Array
    (
        [0] => SimpleXMLElement Object
            (
                [0] => 94351
            )
    )

 )

this is the code i have writen to read from the xml file

$root = new SimpleXMLElement($xml);     
$cart = array();
foreach ($root->Docs as $Docs) {    
    $x = $Docs;
    $cart[] = array($x);
}
}

but i want my array to look like this failing to get bellow result. im not getting the bellow result. reason i want bellow result is to compare this array to another array

Array
(
[0] => Array
    (
        [0] => 94351
    )

[1] => Array
    (
        [0] => 94352
    )

)

Answer 1

For those, who'll open this question later Just cast SimpleXMLElement to string

E.g:

$cart[] = (string) $x;
