This class implements the SAX ContentHandler API, and could possibly be used directly with a SAX Parser, but is designed to be used manually as shown below.

Example usage:

 import org.xml.sax.helpers.AttributesImpl;
 // send simple row data as node with attributes
 InputStream getDataInputStream(Request req, Response resp) {
 Connection conn = DriverManager.getConnection(ConnectionPoolManager.URL_PREFIX + alias, null, null);
 Statement stmt = conn.createStatement();
 ResultSet resultset = stmt.executeQuery("SELECT NAME, AGE, ID FROM EMPLOYEES");
 AttributesImpl emptyAttr = new AttributesImpl();
 DataEncoder db = new DataEncoder();
 db.startDocument();
 db.startElement("results", emptyAttr);
 while (resultset.next()) {
 AttributesImpl attrs = new AttributesImpl();
 //Output the values as attributes
 attrs.addAttribute("", "name", "", "CDATA", resultset.getString("name"));
 attrs.addAttribute("", "age", "", "CDATA", resultset.getString("age"));
 attrs.addAttribute("", "id", "", "CDATA", resultset.getString("id"));
 db.startElement("row", attrs);
 db.endElement();
 }
 db.endElement();
 db.endDocument();
 OutputStream out = resp.getOutputStream();
 return db.getInputStream();
 }
