(C++) XML Sort by Content

Demonstrates the SortByContent method.

The input XML, available at http://www.chilkatsoft.com/data/fruitSort2.xml, is this:

<root>
    <fruits>
        <apples>
            <apple>fuji</apple>
            <apple>gala</apple>
            <apple>granny smith</apple>
            <apple>honeycrisp</apple>
            <apple>mcintosh</apple>
        </apples>
        <fruit>banana</fruit>
        <fruit>blackberry</fruit>
        <fruit>blueberry</fruit>
        <fruit>orange</fruit>
        <fruit>pear</fruit>
    </fruits>
</root>
