Example

For our examples to work, a xml file named Student.xml is needed in our CLASSPATH. The contents of this XML are the following −

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<student id="10">
   <age>12</age>
   <name>Malik</name>
</student>

The following example shows the usage of Javax.xml.parsers.DocumentBuilder.getSchema() method.

package com.tutorialspoint;

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

public class DocumentBuilderDemo {

   public static void main(String[] args) {

      // create a new DocumentBuilderFactory
      DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();

      try {
         // use the factory to create a documentbuilder
         DocumentBuilder builder = factory.newDocumentBuilder();

         // get the Schema used by our builder
         Schema a = builder.getSchema();

         // print the schema if there is any
         System.out.println("" + a);

      } catch (Exception ex) {
         ex.printStackTrace();
      }
   }
}

If we compile the code and execute it, this will produce the following result −

null
