(Lianja) Iterate over Direct Children with a Specific Tag

Demonstrates how to iterate over direct children having a specific tag.

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

<root>
    <fruit color="red">apple</fruit>
    <fruit color="green">pear</fruit>
    <veg color="orange">carrot</veg>
    <meat animal="cow">beef</meat>
    <xyz>
        <fruit color="blue">blueberry</fruit>
        <veg color="green">broccoli</veg>
    </xyz>
    <fruit color="purple">grape</fruit>
    <cheese color="yellow">cheddar</cheese>
</root>

    // Do the same as the above loop, but instead of creating
    // a new object instance for each child, call GetNthChildWithTag2 to
    // update the object's reference instead.

        // Navigate to the Nth child.
