Acess Simple xml object attributes

I am having a very strange issue i have a xml file structure like this

<hooks>
    <hook module="socialsharing" hook="displayHeader" position="1"/>
    <hook module="socialsharing" hook="displayRightColumnProduct" position="1"/>
    <hook module="socialsharing" hook="actionObjectProductUpdateAfter" position="1"/>
    <hook module="socialsharing" hook="actionObjectProductDeleteAfter" position="1"/>
    <hook module="socialsharing" hook="displayCompareExtraInformation" position="1"/>
    <hook module="blockbanner" hook="displayHeader" position="2"/>
    <hook module="blockbanner" hook="displayBanner" position="1"/>
    <hook module="blockbanner" hook="actionObjectLanguageAddAfter" position="1"/>
    <hook module="blockbestsellers" hook="displayLeftColumn" position="1" exceptions="category"/>
    <hook module="blockbestsellers" hook="displayHeader" position="3"/>
    <hook module="blockbestsellers" hook="actionProductAdd" position="1"/>
    <hook module="blockbestsellers" hook="actionProductUpdate" position="1"/>
</hooks>

And This is the code snipplet i am working with

if($xmlHooks=simplexml_load_file(_PS_ROOT_DIR_.'/assests/hooks.xml'))
        {


            foreach ($xmlHooks as $xmlHook)
            {
                die(print_r($xmlHook->attributes()->module));

            }   

        }

BUt it always output me no matter how i acess it

SimpleXMLElement Object
(
    [0] => socialsharing
)

Just want to get socialsharing freely not in array or object so i can use this word further

Thanks!
