现在有很多的xml工具软件都能根据xsd文件书写出xml文档，.net 没有实现此方法，如是我写了几个浏览、校验、和创建xml的方法
全部代码如下：
using system;
using system.data;
using system.configuration;
using system.web;
using system.web.security;
using system.web.ui;
using system.web.ui.webcontrols;
using system.web.ui.webcontrols.webparts;
using system.web.ui.htmlcontrols;
using system.xml;
using system.xml.schema;
using system.collections;
