XML在我们的程序中用到的越来越多，因为它存储、读取、修改都比较方便。
下面我来分享一下XML的常用操作(增删改查)，下面是程序运行效果：
增(增加节点包括创建XML):
/// <summary>
/// 创建XML文档
/// </summary>
/// <param name="path"></param>
......
1.route.xml文件内容
<?xml version="1.0" encoding="GBK"?>
<root>
<route id="1111">
<id>111</id>
<name>四川</name>
<path>www.baidu.com/hehe.html</path>
</route>
</root>
2.test.html代码
<html>
<body>
<script> ......
