(Node.js) 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:

<root>
    <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:
    console.log("model = " + carNode.GetAttrValue("model"));

    // Get the value of the "hp" attribute as an integer:
    horsepower = carNode.GetAttrValueInt("hp");
    console.log("horsepower = " + horsepower);

    // Iterate over the attributes and show the name/value of each:
    numAttr = carNode.NumAttributes;

    while (i < numAttr) {
        console.log(carNode.GetAttributeName(i) + ": " + carNode.GetAttributeValue(i));
