(Android™) AddAttribute - Insert New Attribute in an XML Node

Demonstrates adding an name=value attribute to an XML element.

This example uses the XML sample file here: sample1.xml. The sample1.xml file contains this content:

Chilkat Android™ Downloads Android™ Java Libraries Android C/C++ Libraries

// 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);

    CkXml xml = new CkXml();

    boolean success = xml.LoadXmlFile("qa_data/xml/sample1.xml");
    if (success != true) {
        Log.i(TAG, xml.lastErrorText());
        return;
        }

    // Navigate to the "books" element:
    boolean bFound = xml.FindChild2("books");
    if (bFound == false) {
        Log.i(TAG, "No books child found!");
        return;
        }

    int numChildren = xml.get_NumChildren();

    int i = 0;
    while (i < numChildren) {

        // Navigate to the Nth book 
        xml.GetChild2(i);

        // Display the book title:
        Log.i(TAG, xml.getAttrValue("title"));

        // Add a new integer attribute:
        // Should never fail..
        xml.AddAttributeInt("bookId",i);

        // Add a new unread="yes" attribute:
        xml.AddAttribute("unread","yes");

        // Navigate back up to the parent:
        xml.GetParent2();

        i = i + 1;
        }

    // Navigate back to the document root:
    xml.GetRoot2();

    // Save the updated document:
    success = xml.SaveXml("modified.xml");
    if (success != true) {
        Log.i(TAG, xml.lastErrorText());
        return;
        }

    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."
