Read UTF-8 XML file using SAX Parser

In this tutorial we are going to see how to read XML file with UTF-8 character using SAX parser.
1. Create Project Called JavaXML.
2. Create package called com.javatutorialscorner.xml.sax under JavaXML.
3. Create Java class called ReadUTF8XMLFile.java under com.javatutorialscorner.xml.sax package.
ReadUTF8XMLFile.java

package com.javatutorialscorner.xml.sax;
 
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.Reader;
 
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;
 
import org.xml.sax.Attributes;
import org.xml.sax.InputSource;
import org.xml.sax.SAXException;
import org.xml.sax.helpers.DefaultHandler;
 
public class ReadUTF8XMLFile {
 
 /**
  * @param args
  */
 public static void main(String[] args) {
  // TODO Auto-generated method stub
  try {
   SAXParserFactory saxParserFactory = SAXParserFactory.newInstance();
   SAXParser parser = saxParserFactory.newSAXParser();
   DefaultHandler defaultHandler = new DefaultHandler() {
    boolean firstName = false;
    boolean lastName = false;
    boolean petName = false;
 
    public void startElement(String uri, String localName,
      String qName, Attributes attribute) throws SAXException {
     System.out.println("Start Element : " + qName);
     if (qName.equalsIgnoreCase("FIRSTNAME")) {
      firstName = true;
     }
     if (qName.equalsIgnoreCase("LASTNAME")) {
      lastName = true;
     }
     if (qName.equalsIgnoreCase("PETNAME")) {
      petName = true;
     }
    }
 
    public void endElement(String uri, String localName,
      String qName) throws SAXException {
     System.out.println("End Element : " + qName);
    }
 
    public void characters(char ch[], int start, int length)
      throws SAXException {
     if (firstName) {
      System.out.println("First Name : "
        + new String(ch, start, length));
      firstName = false;
     }
     if (lastName) {
      System.out.println("Last Name : "
        + new String(ch, start, length));
      lastName = false;
     }
     if (petName) {
      System.out.println("Pet Name : "
        + new String(ch, start, length));
      petName = false;
 
     }
    }
   };
   File xmlFile = new File("C:\\jtc\\student.xml");
   InputStream inputStream = new FileInputStream(xmlFile);
   Reader reader = new InputStreamReader(inputStream, "UTF-8");
   InputSource inputSource = new InputSource(reader);
   parser.parse(inputSource, defaultHandler);
  } catch (ParserConfigurationException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  } catch (SAXException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  } catch (IOException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
 
 }
 
}

If you parse XML file that contains UTF character that throws error.So avoid this error convert xml to UTF-8 InputStream by using following lines of code.

File xmlFile = new File("C:\\jtc\\student.xml");
   InputStream inputStream = new FileInputStream(xmlFile);
   Reader reader = new InputStreamReader(inputStream, "UTF-8");
   InputSource inputSource = new InputSource(reader);
   parser.parse(inputSource, defaultHandler);

student.xml

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<college>
<student>
<firstname>Shiva</firstname>
<lastname>J</lastname>
<petname>§</petname>
</student>
</college>

Now you can run the program see the following output in console.

Start Element : college

Start Element : student

Start Element : firstname

First Name : Shiva

End Element : firstname

Start Element : lastname

Last Name : J

End Element : lastname

Start Element : petname

Pet Name : §

End Element : petname

End Element : student

End Element : college
