Demonstrates the SortByTag method.

The input XML, available at http://www.chilkatsoft.com/data/fruitSort1.xml, is this:

<root>
    <fruits>
        <apple>
            <fuji>blah</fuji>
            <gala>blah</gala>
            <grannySmith>blah</grannySmith>
            <honeycrisp>blah</honeycrisp>
            <mcIntosh>blah</mcIntosh>
        </apple>
        <banana>blah</banana>
        <blackberry>blah</blackberry>
        <blueberry>blah</blueberry>
        <orange>blah</orange>
        <pear>blah</pear>
    </fruits>
</root>
