(Unicode C) Find Direct Child with Specific TagDemonstrates how to find a direct child 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>
