我有这个代码

private void nextActionPerformed(java.awt.event.ActionEvent evt) {
   File myfile;
   FileInputStream   myInputStream;
   InputStreamReader myInputStreamReader; 
   BufferedReader    myBufferedReader;

   String databasedir =
      "C:\\Users\\himu\\Documents\\NetBeansProjects\\database\\src\\database\\databases\\";
   try{
      myfile              = new File(databasedir+dbname.getText());
      myInputStream       = new FileInputStream(myfile);
      myInputStreamReader = new InputStreamReader(myInputStream);
      myBufferedReader    = new BufferedReader(myInputStreamReader);

      String xmlval =
         "<database>"
         + "<db id ="  +dbname.getText() +">"
         + " <dbfileloc>" +myfile
         + "</dbfileloc>  "
         + "</db>"
         + "</database>";
   }
   catch(Exception e)
   {
   }

You might want to consider one of the XML parsers to read and write a pre-existing XML document. Try Stax

您可能希望考虑使用其中一个XML解析器来读取和写入预先存在的XML文档。试试Stax
