Demonstrates some methods for getting attribute name/values.

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

#import <CkoXml.h>

CkoXml *xml = [[CkoXml alloc] init];
CkoXml *carNode = 0;
int numAttr;
int horsepower;
int i;

BOOL success;
// The sample input XML is available at http://www.chilkatsoft.com/data/car.xml
success = [xml LoadXmlFile: @"car.xml"];
if (success != YES) {
    NSLog(@"%@",xml.LastErrorText);
    return;
}

// Navigate to the "car" node, which is the 1st child:
carNode = [xml FirstChild];

// Get the value of the "model" attribute:
NSLog(@"%@%@",@"model = ",[carNode GetAttrValue: @"model"]);

// Get the value of the "hp" attribute as an integer:
horsepower = [[carNode GetAttrValueInt: @"hp"] intValue];
NSLog(@"%@%d",@"horsepower = ",horsepower);

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

i = 0;
while (i < numAttr) {
    NSLog(@"%@%@%@",[carNode GetAttributeName: [NSNumber numberWithInt: i]],@": ",[carNode GetAttributeValue: [NSNumber numberWithInt: i]]);
    i = i + 1;
}
