How do I create XML output as string without the ?xml ? tag

Question

I need to create xml from a database query result. I am able to do this but it includes the <?xml ?> header tag. I need to create the xml without the header tag <?xml ?>. Please advise.
Here is my source:
package sql_test;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;
import javax.xml.transform.dom.*;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import java.sql.*;
public class SQLConnector {
     java.sql.Connection conn;
     public SQLConnector()
            conn = null;
             try {
                     Class.forName("com.mysql.jdbc.Driver").newInstance();
                     conn = DriverManager.getConnection("jdbc:mysql://localhost/test", "admin", "admin");
                   } catch(Exception e) {
                     System.err.println("Exception: " + e.getMessage());
     public String getTestData()
          Document doc = null;
          Statement s = null;
          ResultSet rs = null;
          String str = null;
          try {
               DocumentBuilderFactory factory =
              DocumentBuilderFactory.newInstance();
              DocumentBuilder builder = factory.newDocumentBuilder();
              doc = builder.newDocument();
              Element results = doc.createElement("Results");
              doc.appendChild(results);
               s = conn.createStatement();
               s.executeQuery("select * from test_table");
               rs = s.getResultSet ();
              ResultSetMetaData rsmd = rs.getMetaData();
              int colCount = rsmd.getColumnCount();
                while (rs.next()) {
                    Element row = doc.createElement("Row");
                    results.appendChild(row);
                    for (int ii = 1; ii <= colCount; ii++) {
                       String columnName = rsmd.getColumnName(ii);
                       Object value = rs.getObject(ii);
                       Element node = doc.createElement(columnName);
                       node.appendChild(doc.createTextNode(value.toString()));
                       row.appendChild(node);
              str = getDocumentAsXml(doc);
         catch (Exception e) {
             e.printStackTrace();
         finally {
           try {
             if (conn != null) conn.close();
             if (s != null) s.close();
             if (rs != null) rs.close();
           catch (Exception e) {
         return str;
     public static String getDocumentAsXml(Document doc) throws TransformerConfigurationException, TransformerException
          DOMSource domSource = new DOMSource(doc);
          TransformerFactory tf = TransformerFactory.newInstance();
          Transformer transformer = tf.newTransformer();
          transformer.setOutputProperty(OutputKeys.INDENT, "yes");
          java.io.StringWriter sw = new java.io.StringWriter();
          StreamResult sr = new StreamResult(sw);
          transformer.transform(domSource, sr);
          return sw.toString();
}
