Android provides the facility to parse the xml file using SAX, DOM etc. parsers. The SAX parser cannot be used to create the XML file, It can be used to parse the xml file only.

Advantage of SAX Parser over DOM

It consumes less memory than DOM.

Example of android SAX Xml parsing

activity_main.xml

Drag the one textview from the pallete. Now the activity_main.xml file will look like this:

File: activity_main.xml

xml document

Create an xml file named file.xml inside the assets directory of your project.

File: file.xml

Activity class

Now write the code to parse the xml using sax parser.

File: MainActivity.java
package com.javatpoint.saxxmlparsing;  
  
  
import java.io.InputStream;  
import javax.xml.parsers.SAXParser;  
import javax.xml.parsers.SAXParserFactory;  
import org.xml.sax.Attributes;  
import org.xml.sax.SAXException;  
import org.xml.sax.helpers.DefaultHandler;  
import android.app.Activity;  
import android.os.Bundle;  
import android.widget.TextView;  
public class MainActivity extends Activity {  
TextView tv;  
@Override  
  
public void onCreate(Bundle savedInstanceState) {  
super.onCreate(savedInstanceState);  
setContentView(R.layout.activity_main);  
tv=(TextView)findViewById(R.id.textView1);  
try {  
SAXParserFactory factory = SAXParserFactory.newInstance();  
  
SAXParser saxParser = factory.newSAXParser();  
  
  
DefaultHandler handler = new DefaultHandler() {  
  
boolean name = false;  
  
boolean salary = false;  
  
  
public void startElement(String uri, String localName,String qName,  
Attributes attributes) throws SAXException {  
if (qName.equalsIgnoreCase("name"))  
{  
name = true;  
}  
if (qName.equalsIgnoreCase("salary"))  
{  
salary = true;  
}  
}//end of startElement method  
public void endElement(String uri, String localName,  
String qName) throws SAXException {  
}  
  
public void characters(char ch[], int start, int length) throws SAXException {  
if (name) {  
  
tv.setText(tv.getText()+"\n\n Name : " + new String(ch, start, length));  
name = false;  
}  
if (salary) {  
tv.setText(tv.getText()+"\n Salary : " + new String(ch, start, length));  
salary = false;  
}  
}//end of characters  
 method  
};//end of DefaultHandler object  
  
InputStream is = getAssets().open("file.xml");  
saxParser.parse(is, handler);  
  
} catch (Exception e) {e.printStackTrace();}  
}  
}

Output:

SAX Xml Parsing
