Writing XML in multiple lines

Question

Hi,
I am running into a glitch when i tried to write multiple XMLs into 1 file (each XML on each line).
I am using XMLWriter and trying to use CompactFormat (in XMLWriter).
Let me first explain my problem. I am trying to write several XML lines (let's say orders) into 1 file and i want each order to be in a single line. My problem is that all the xml orders are coming in the same line because i am using the compact format.. How can i make each order xml go into different lines in the same file?
                    try
                         OutputFormat format = OutputFormat.createPrettyPrint();
                         format = OutputFormat.createCompactFormat();
                         format.setSuppressDeclaration(true);
                         fileOutputStream = new FileOutputStream("C:\\CODE\\FINAL\\test.txt");
                         xmlWriter = new XMLWriter(fileOutputStream, format);
                    } catch(Exception e)
                         System.out.println("File not found");
                    }After this, i will prepare XML using DOM4J APIs and write that to this file using XMLWriter.
Please help me how to write into different line..
Thanks in advance

One way is to first convert each XML into a string, e.g. via
      * Prints a textual representation of a DOM object into a text string..
      * @param document DOM object to parse.
      * @return String representation of <i>document</i>.
    static public String toString(Document document) {
        String result = null;
        if (document != null) {
            StreamResult strResult = new StreamResult(new StringWriter());
            try {
                Transformer t = TransformerFactory.newInstance().newTransformer();
                t.setOutputProperty(OutputKeys.ENCODING, "iso-8859-1");
                t.setOutputProperty(OutputKeys.INDENT, "yes");
                t.setOutputProperty(OutputKeys.METHOD, "xml"); //xml, html, text
                t.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "4");
                t.transform(new DOMSource(document.getDocumentElement()), strResult);
            } catch (Exception e) {
                e.printStackTrace();
            result = strResult.getWriter().toString();
        return result;
    }//toString()then remove all line separators and add the result to the file followed by a line separator.
