Demonstrates how to update XML attributes.

The output XML is this:

Chilkat2 Java

import com.chilkatsoft.chilkat2.Xml;

public class ChilkatExample {

    public static void main(String[] args) {
        Xml xml = new Xml();

        xml.loadXml("<abc a=\"123\" b=\"apple\">Test</abc>");

        // The UpdateAttribute and AddOrUpdateAttribute methods
        // are identical.  Both will replace the attribute's value if it
        // already exists, or insert a new attribute if it does not yet exist.

        // Change the value of attribute "b" to "pear".
        xml.updateAttribute("b", "pear");

        // Because no attribute named "c" exists, UpdateAttribute
        // will create it:
        xml.updateAttribute("c", "orange");

        // If an attribute's value is an integer, the AddToAttribute
        // method may be called to update it by adding an integer value.
        // For example, update the value of "a" to "130" by adding 7.
        xml.addToAttribute("a", 7);

        // Examine the result:
        System.out.println(xml.getXml());
    }
