    Default Write an xml dom to a xml file

    I have got the xml to print in the system, but I want to have that printed into a .xml file, how do I do that? Here is what I got so far
    import javax.xml.stream.*;
     
    import javax.xml.parsers.DocumentBuilder;
    import javax.xml.parsers.DocumentBuilderFactory;
    import org.w3c.dom.Document;
    import java.io.*;
     
    public class XMLWriter {
     
     
       public static void main(String[] args) throws XMLStreamException  {
     
       File xmlFile = new File("file.xml");
       try{
           Document document;
           FileWriter fstream = new FileWriter(xmlFile);
           BufferedWriter out = new BufferedWriter(fstream);
           DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
           DocumentBuilder builder = factory.newDocumentBuilder();
     
          // Create an output factory
          XMLOutputFactory xmlof = XMLOutputFactory.newInstance();
     
          // Create an XML stream writer
          XMLStreamWriter xmlw = xmlof.createXMLStreamWriter(System.out);
     
          xmlw.writeStartDocument();
          xmlw.writeDTD("<!DOCTYPE file SYSTEM \"file.dtd\">");
          xmlw.writeStartElement("file");
          xmlw.writeEmptyElement("filename");
          xmlw.writeAttribute("filename", "ReadMe.txt");
          xmlw.writeEmptyElement("keyword");
          xmlw.writeAttribute("keyword", "Some word to match");
          xmlw.writeEmptyElement("option");
          xmlw.writeAttribute("option", "matchcase");
     
     
          // Write document end. This closes all open structures
          xmlw.writeEndDocument();
          // Close the writer to flush the output
     
          xmlw.close();
           }catch (Exception e){//Catch exception if any
          System.err.println("Error: " + e.getMessage());
        }
     
       }
     
    }

    Default Re: Write an xml dom to a xml file

    See a) the API for XMLOutputFactory - the method createXMLStreamWriter takes an OutputStream to write to (currently you are using System.out) b) See FileOutputStream (Java Platform SE 6). In other words, create a FileOutputStream and pass this instead of System.out

    XMLStreamWriter xmlw = xmlof.createXMLStreamWriter(new FileOutputStream("file.xml"));
