Hi,

I want to append data to xml file using java.
but it never be added to my users.xml file.

<?xml version="1.0" encoding="iso-8859-1"?>
<logins>
    <user id="xxx" system="yyy" envlib="AAA" env="2" prefix="SPW" depot="NL2" proddiv="FD" lang="NED" />
    <user id="xxx" system="yyy" envlib="AAA" env="2" prefix="SPW" depot="NL2" proddiv="FD" lang="NED" />
    <user id="xxx" system="yyy" envlib="AAA" env="4" prefix="SPR" depot="ASD" proddiv="AV" lang="NED" />
</logins>



this is my code :

String strFileName = getServletContext().getRealPath("/xml/user/users.xml");
   File file = new File(strFileName);
   Document doc = null;
   try{

       DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
       DocumentBuilder db = dbf.newDocumentBuilder();
       doc = db.parse(file);
       }
   catch(IOException e){
       System.out.println(e);
       }


    Element root = doc.getDocumentElement();
    String nodeValue = root.getNodeName();
    out.println(root.getParentNode().getNodeName());

    Element newElement = doc.createElement("user");
    newElement.setAttributeNode(doc.createAttribute("i d"));
    newElement.setAttribute("id", "andhiez");
    newElement.setAttributeNode(doc.createAttribute("s ystem"));
    newElement.setAttribute("system", "andhiez");
    newElement.setAttributeNode(doc.createAttribute("e nvlib"));
    newElement.setAttribute("envlib", "andhiez");
    newElement.setAttributeNode(doc.createAttribute("e nv"));
    newElement.setAttribute("env", "andhiez");
    newElement.setAttributeNode(doc.createAttribute("p refix"));
