dom4j读取xml，对这个xml修改后写入一个新的文件

Question

现在发现问题：

新写入的这个文件，对比就文件发现在代码格式上有区别

我现在想做到修改的地方修改，没修改的地方不需要修改~

即时缩进严重不靠谱

//加载
SAXReader reader = new SAXReader();  
Document document = reader.read(new File(fileName));
//打印了一下发现这个时候似乎格式已经不对了
System.out.print(document.asXML()); 

//对document 进行修改，此时忽略

 //写入一个文件（此处都没敢使用格式）
XMLWriter writer = new XMLWriter(new FileOutputStream(destFile));
writer.write(document);
writer.close();

原来的xml：

<?xml version="1.0" encoding="UTF-8"?>
<!-- edited with XMLSpy v2008 rel. 2 sp2 (http://www.altova.com) by xdowns.com (xdowns.com) -->

                              <property name="encoding" 
                              value="UTF-8" />
                    </bean>
  <bean></bean>
</beans>

生成后的XML：

<?xml version="1.0" encoding="UTF-8"?>

           http://www.springframework.org/schema/lang http://www.springframework.org/schema/lang/spring-lang-2.0.xsd
           http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">

  <!-- Service -->
  <bean id="baseService" class="com.test.test" >
                              <property name="encoding" 
                              value="UTF-8" />
                    </bean>
  </bean/>
</beans>

第二行注释部分没有换行

倒数第二行标签变了样子

你修改这個XML文件的代码是怎么写的，能贴出来看看么？
