Update an XML Attribute

See more XML Examples

Demonstrates how to update XML attributes.

The output XML is this:

<abc b="pear" c="orange" a="130">Test</abc>

Java

import com.chilkatsoft.*;

public class ChilkatExample {

  static {
    try {
        System.loadLibrary("chilkat");
    } catch (UnsatisfiedLinkError e) {
      System.err.println("Native code library failed to load.\n" + e);
      System.exit(1);
    }
  }

  public static void main(String argv[])
  {
    boolean success = false;

    CkXml xml = new CkXml();

    success = 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".
    success = xml.UpdateAttribute("b","pear");

    // Because no attribute named "c" exists, UpdateAttribute
    // will create it:
    success = 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());
  }
