            <apple>granny smith</apple>
            <apple>honeycrisp</apple>
            <apple>mcintosh</apple>
        </apples>
        <fruit>banana</fruit>
        <fruit>blackberry</fruit>
        <fruit>blueberry</fruit>

#  Note:  The "apples" node contains child nodes, but its
#  text content is 0-length (empty).  Therefore, when sorting in
#  ascending order, it will be positioned before the direct
