Hi,

Following code might be useful:

import java.io.StringReader;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;

import org.w3c.dom.Document;
import org.xml.sax.InputSource;


public class UpdateData
{
public static void main(String[] args) 
{


String url="http://www.roseindia.net";
String strData = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n";
    strData = strData+"<urlset xmlns=\"http://www.sitemaps.org/schemas/sitemap/0.9\" 
xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" 

xsi:schemaLocation=\"http://www.sitemaps.org/schemas/sitemap/0.9 

http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd\">\n";

        strData = strData+" <url>\n";
        strData = strData+"     <loc><![CDATA[\"http://www.roseindia.net" + url +"\"]]></loc>\n";
        strData = strData+"     <changefreq>weekly</changefreq>\n";
        strData = strData+"     <priority>1.00</priority>\n";
        strData = strData+" </url>\n";

        strData = strData+"</urlset>\n";


System.out.println(strData);

    System.out.println("hello");



try {
  DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
  DocumentBuilder builder = factory.newDocumentBuilder();
  InputSource is = new InputSource( new StringReader( strData ) );
  Document d = builder.parse( is );
}
catch( Exception ex ) {
  ex.printStackTrace();
}
}

}

Thanks
