Hi,

Java programming language has many API's to create xml file from program.

Here is the code example:

import org.w3c.dom.*;
import javax.xml.parsers.*;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;
import javax.xml.transform.dom.*;

public class TestDOM {
public TestDOM() { }
public String doit()
throws javax.xml.parsers.ParserConfigurationException,
javax.xml.transform.TransformerException,
javax.xml.transform.TransformerConfigurationException{

DocumentBuilderFactory factory
= DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
DOMImplementation impl = builder.getDOMImplementation();

Document doc = impl.createDocument(null,null,null);
Element e1 = doc.createElement("howto");
doc.appendChild(e1);

Element e2 = doc.createElement("java");
e1.appendChild(e2);

e2.setAttribute("url","http://www.google.com";);


// transform the Document into a String
DOMSource domSource = new DOMSource(doc);
TransformerFactory tf = TransformerFactory.newInstance();
Transformer transformer = tf.newTransformer();
//transformer.setOutputProperty
(OutputKeys.OMIT_XML_DECLARATION, "yes");
transformer.setOutputProperty(OutputKeys.METHOD, "xml");
transformer.setOutputProperty(OutputKeys.ENCODING,"ISO-8859-1");
transformer.setOutputProperty
("{http://xml.apache.org/xslt}indent-amount";, "4");
transformer.setOutputProperty(OutputKeys.INDENT, "yes");
java.io.StringWriter sw = new java.io.StringWriter();
StreamResult sr = new StreamResult(sw);
transformer.transform(domSource, sr);
String xml = sw.toString();
return xml;
}

public static void main(String args[])
throws javax.xml.parsers.ParserConfigurationException,
javax.xml.transform.TransformerException,
javax.xml.transform.TransformerConfigurationException{
System.out.println(new TestDOM().doit());

}
}

Thanks
