get value of enc:arraSize from an attribute

Hi 

Im trying to get the value of hotels enc:arraySize, and I do not know how to, could you please help me with this?

<return xsi:type="enc:Struct">
    <session xsi:type="xsd:string">5762c037bc3a8</session> // To read what is in session on a transfer I do it like this //sesssion
    <hotels enc:itemType="enc:Struct" enc:arraySize="235" xsi:type="enc:Array">
        <item xsi:type="enc:Struct">
