Adding DOCTYPE to a  XML File

     

In this section, you will learn to add a DOCTYPE to your XML file  using the DOM APIs. 

Description of program:

The following program helps to add a  DOCTYPE in your XML  file. Program takes a XML file name on the console and it checks, the given file exists or not. If the given file exists then it is  parsed using the parse() method and a Document object treee is created . Abstract class Transformer is used to transform a source tree into a xml file The setOutputProperty() method invokes to the Transformer object and sets the systemId and publicId to the  DOCTYPE in the XML file. 

Here is the XML File: Employee-Detail.xml

<?xml version = "1.0" ?>
<Employee-Detail>

<Employee>
<Emp_Id> E-001 </Emp_Id>
<Emp_Name> Vinod </Emp_Name>
<Emp_E-mail> [email protected] </Emp_E-mail>
</Employee>

<Employee>
<Emp_Id> E-002 </Emp_Id>
<Emp_Name> Amit </Emp_Name>
<Emp_E-mail> [email protected] </Emp_E-mail>
</Employee>

<Employee>
<Emp_Id> E-003 </Emp_Id>
<Emp_Name> Deepak </Emp_Name>
<Emp_E-mail> [email protected] </Emp_E-mail>
</Employee>

</Employee-Detail>

Here is the Java File: AddDocType.java

import java.io.*;
import javax.xml.parsers.*;
import org.w3c.dom.*;
import org.xml.sax.*;
import javax.xml.transform.*; 
import javax.xml.transform.dom.DOMSource; 
import javax.xml.transform.stream.StreamResult;

public class AddDocType{
  static public void main(String[] args){
  try{
  BufferedReader bf = new BufferedReader(
 
new InputStreamReader(System.in));
  System.out.print("Enter XML file name: ");
  String xmlFile = bf.readLine();
  System.out.println();
  File file = new File(xmlFile);
  if (file.exists()){
  DocumentBuilderFactory factory = 
  DocumentBuilderFactory.newInstance
();
  DocumentBuilder builder = factory.newDocumentBuilder();
  Document doc = builder.parse(xmlFile);
//  Create transformer
  Transformer tFormer = 
  TransformerFactory.newInstance
().newTransformer();
//  Set system id
  tFormer.setOutputProperty(
  OutputKeys.DOCTYPE_SYSTEM, 
"systmId");

  Source source = new DOMSource(doc);
  Result result = new StreamResult(System.out);
  tFormer.transform(source, result);
  System.out.println();
  }
  else{
  System.out.println("File not found!");
  }
  }
  catch (Exception e){
  e.getMessage();
  }
  }
}
