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>

Android™

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
package com.test;

import android.app.Activity;
import com.chilkatsoft.*;

import android.widget.TextView;
import android.os.Bundle;

public class SimpleActivity extends Activity {

  private static final String TAG = "Chilkat";

  // Called when the activity is first created.
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    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:
    Log.i(TAG, xml.getXml());

  }

  static {
      System.loadLibrary("chilkat");

      // Note: If the incorrect library name is passed to System.loadLibrary,
      // then you will see the following error message at application startup:
      //"The application <your-application-name> has stopped unexpectedly. Please try again."
