(MFC) Methods for Getting Attributes

Demonstrates some methods for getting attribute name/values.

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

    <car color="black" make="mercedes" model="C350" hp="302" engine="v6" type="sedan">Mercedes Benz C350</car>
</root>

    //  Navigate to the "car" node, which is the 1st child:
    carNode = xml.FirstChild();

    //  Get the value of the "model" attribute:
    strOut.append("model = ");
    strOut.append(carNode->GetAttrValue("model"));
    strOut.append("\r\n");

    //  Get the value of the "hp" attribute as an integer:

    strOut.append("horsepower = ");
    strOut.appendInt(horsepower);
