You have to use nested foreach:

foreach( $xml->object->field as $key => $value )
{
    (...)
    if( $value['name'] == 'scans' )
    {
        foreach( $value->object as $obj )
        {
            /* Here you can output <object> attributes */
            foreach( $obj->field as $field )
            {
                /* Here you can output <field> attributes and values */
            }
        }
    }
}
