如何將字符串添加到現有的XML文件中的Java

Question

可能重複：
Append node to an existing xml-Java

我有這個代碼

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) 
    { 
    } 
} 

**我想在已創建的具有此位置的dbrepoloc.xml文件中的xmlval的先前條目之後附加字符串xmlval C：\ User s \ himu \ Documents \ NetBeansProjects \ database \ src \ database \ dbrepoloc.xml我沒有得到確切的代碼，上面提到的地方請幫我

你可能想要考慮一個XML解析器來讀寫一個預先存在的XML文檔。嘗試Stax
