Android UI Layout (activity_main.xml)

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginLeft="86dp"
        android:layout_marginTop="77dp"
        android:text="TextView" />

</RelativeLayout>

Android Activity (MainActivity.java)

package com.androidsurya.xmlparsing;

import java.io.InputStream;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;

import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;

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

public class MainActivity extends Activity {
TextView textView;
InputStream inputStream;
DocumentBuilderFactory dbFactory;
DocumentBuilder docBuilder;
Document doc;
Element element;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView = (TextView) findViewById(R.id.textView1);
try {
inputStream = getAssets().open("employeesdetails.xml");

dbFactory = DocumentBuilderFactory.newInstance();
docBuilder = dbFactory.newDocumentBuilder();
doc = docBuilder.parse(inputStream);

element = doc.getDocumentElement();
element.normalize();

NodeList nList = doc.getElementsByTagName("employee");
for (int i = 0; i < nList.getLength(); i++) {

Node node = nList.item(i);
if (node.getNodeType() == Node.ELEMENT_NODE) {
Element element2 = (Element) node;
textView.setText(textView.getText() + "\nEmployee Id : "
+ getValuefromTagName("employee_id", element2) + "\n");
textView.setText(textView.getText() + "Employee Name : "
+ getValuefromTagName("employee_name", element2) + "\n");
textView.setText(textView.getText() + "Employee Salary: "
+ getValuefromTagName("employee_salary", element2) + "\n");
textView.setText(textView.getText()
+ "===========================");
}
}
} catch (Exception e) {
e.printStackTrace();
}

}

private static String getValuefromTagName(String tag, Element element) {
NodeList nodeList = element.getElementsByTagName(tag).item(0)
.getChildNodes();
Node node = (Node) nodeList.item(0);
return node.getNodeValue();
}

}

Register Activity in Android Manifest file

 <activity
            android:name="com.androidsurya.xmlparsing.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
