Hi Friend,

To create XML using DTD,you need to create a dtd 'students.dtd':
<?xml version="1.0" encoding="UTF-8"?>
<!-- JavaZOOM Sample -->
<!ELEMENT STUDENTS (USER*)>
<!ELEMENT STUDENT (#PCDATA)>
<!ATTLIST STUDENT
MARKS CDATA #REQUIRED
>

Now create java file 'CreateXML.java'
import java.io.*;
import org.w3c.dom.*;
import javax.xml.parsers.*;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;
import javax.xml.transform.dom.*;
public class CreateXML{
public static void main(String[]args) throws Exception{
PrintWriter out = new PrintWriter(new FileOutputStream("student.xml"));
Document xmldoc = null;
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
DOMImplementation impl = builder.getDOMImplementation();
Element e = null;
Node n = null;
xmldoc = impl.createDocument(null, "USERS", null);
Element root = xmldoc.getDocumentElement();
String[] marks = {"95","92","90"};
String[] desc = {"Angelina","Simran","Martina"};
for (int i=0;i<marks.length;i++){
e = xmldoc.createElementNS(null, "USER");
e.setAttributeNS(null, "Marks", marks[i]);
n = xmldoc.createTextNode(desc[i]);
e.appendChild(n);
root.appendChild(e);
}
DOMSource domSource = new DOMSource(xmldoc);
StreamResult streamResult = new StreamResult(out);
TransformerFactory tf = TransformerFactory.newInstance();
Transformer serializer = tf.newTransformer();
serializer.setOutputProperty(OutputKeys.ENCODING,"ISO-8859-1");
serializer.setOutputProperty(OutputKeys.DOCTYPE_SYSTEM,"students.dtd");
serializer.setOutputProperty(OutputKeys.INDENT,"yes");
serializer.transform(domSource, streamResult);
}
}
Thanks
