To clone an XML document at runtime, use the StAX XMLEventReader and XMLEventWriter classes like this:
//AirWings_order.xml - the original XML in this example
//AirWings_order_clone.xml - the clone of AirWings_order.xml
import javax.xml.stream.*;
import java.io.*;
public class StAXBasicEventWriter_clone{
public StAXBasicEventWriter_clone(){}
public static void main(String[] args)
{
XMLInputFactory XMLif=null;
XMLOutputFactory XMLof=null;
XMLEventReader XMLer=null;
XMLEventWriter XMLew=null;
System.setProperty("javax.xml.stream.XMLInputFactory",
"com.sun.xml.stream.ZephyrParserFactory");
System.setProperty("javax.xml.stream.XMLOutputFactory",
"com.sun.xml.stream.ZephyrWriterFactory");
//get the XMLInputFactory and XMLOutputFactory objects
XMLif=XMLInputFactory.newInstance();
XMLof=XMLOutputFactory.newInstance();
//get the XMLEventReader and XMLEventWriter objects
try{
XMLer=XMLif.createXMLEventReader
("file:///C://Data_Local//xml//docs//",
new FileReader
("C://Data_local//xml//docs//AirWings_order.xml"));
XMLew=XMLof.createXMLEventWriter(
new FileWriter
("C://Data_local//xml//docs//AirWings_order_clone.xml"));
}catch(java.io.IOException e)
{System.out.println(e.getMessage());
}catch(javax.xml.stream.XMLStreamException e)
{System.out.println(e.getMessage());}
//generate the XML document
try{
XMLew.add(XMLer);
//clean up
XMLew.close();
XMLer.close();
}catch(javax.xml.stream.XMLStreamException e)
{System.out.println(e.getMessage());}
}
