    // 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)")
        // Restore the reference back to the parent.
        success = xml.GetParent2()
