<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>

#  The sample input XML is available at http://www.chilkatsoft.com/data/fruit.xml
success = xml.LoadXmlFile("fruit.xml")
if (success != true)

    exit
end

#  Find the direct child node having the tag "meat", and
#  return a new instance of the XML object referencing the
#  child node, if found.
# child is a CkXml
child = xml.FindChild("meat")
if (child == nil )
    print "No direct child having the tag \"meat\" was found." + "\n";
else
    print "Content = " + child.content() + "\n";

end

#  The same can be accomplished without creating a new
#  XML object instance.  Instead, the FindChild2 method updates
#  the caller's internal reference to the found child, if successful.
success = xml.FindChild2("meat")
if (success == true)
    #  Success!  The xml object now references the found child.
    print "Content = " + xml.content() + "\n";
    #  Restore the reference back to the parent.
    xml.GetParent2()
else
    print "No direct child having the tag \"meat\" was found." + "\n";
