(Ruby) 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>

Chilkat Ruby Downloads install from rubygems.org gem install chilkat or download... Ruby Library for Windows, MacOS, Linux, Alpine Linux

require 'chilkat'

xml = Chilkat::CkXml.new()

# The sample input XML is available at http://www.chilkatsoft.com/data/car.xml
success = xml.LoadXmlFile("car.xml")
if (success != true)
    print xml.lastErrorText() + "\n";
    exit
end

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

# Get the value of the "model" attribute:
print "model = " + carNode.getAttrValue("model") + "\n";

# Get the value of the "hp" attribute as an integer:
horsepower = carNode.GetAttrValueInt("hp")
print "horsepower = " + horsepower.to_s() + "\n";

# Iterate over the attributes and show the name/value of each:
numAttr = carNode.get_NumAttributes()

i = 0
while i < numAttr
    print carNode.getAttributeName(i) + ": " + carNode.getAttributeValue(i) + "\n";
    i = i + 1
end
