问题描述

我试图修改使用JDOM和变压器的概念XML数据，这两个功能在2.2版本的作品。但每当我试图编译2.1我收到异常。此外，我在谷歌搜索到这个问题，他们提到2.1版不会支持变压器的概念。什么是修改的XML文件的另一种方法。

I tried to modify XML data using JDOm and transformer concept, this two functions are works in 2.2 version. but whenever i tried to compile in 2.1 i am getting exception. Also i searched this issue in google, they mentioned 2.1 version never support transformer concept. what is the alternative way to modify XML file.

String filePath = Environment.getExternalStorageDirectory() + getDir;  
File file = new File(filePath);
if (file.exists()) {
    Document document = (Document) builder.build(file);

    Element root = document.getRootElement();
    Element EditableTag = root.getChild("firsttag");
    EditableTag.setText("changed String");

    /**
     * Print the modified xml document
     */
    String des = new XMLOutputter().outputString(document);
    System.out.println("String: " + des);

    /**
     * Modify the orginal document using FileWritter
     */
    FileWriter fileWriter = new FileWriter(file);
    fileWriter.write(des);
    fileWriter.close();
}

这code是在2.2版本的作品，同时我编这2.1我收到FleNotFound例外。
