(C) XML SearchForTag Method

Demonstrates the SearchForTag and SearchForTag2 methods.

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

<root>
    <searchRoot>
        <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>
    </searchRoot>
    <fruit color="red">strawberry</fruit>
    <fruit color="orange">peach</fruit>
    <root></root>
</root>
