   //输出格式的缩进字符为两个空格
   format.setIndent("  ");
   try {
    //因为输出内容有汉字，所以输出格式的字符编码为GB2312
    format.setEncoding("GB2312");
    //为XML输出对象指定输出格式
    outer.setFormat(format);
    //创建写文件对象
    FileWriter writer = new FileWriter(fileName);
    //将根节点输出到XML文档
    outer.output(doc, writer);
    writer.close();
   } catch (Exception e) {
    e.printStackTrace();
   }
  } 

}

运行后，在目标路径产生了一个以下的XML文档

<?xml version="1.0" encoding="GB2312"?>
<books>
  <!--The sample class for Handling XML-->
  <book id="0">1</book>
  <book id="1">2</book>
  <book id="2">3</book>
  <book id="3">4</book>
</books>
