通過XmlDocument修改帶有DOCTYPE的xml文件遇到如下問題：1，斷網時直接報錯：無法解析此遠程名稱- 'hibernate.sourceforge.net'2，連網時修改后：在DOCTYPE行后產生多余字符"[]"    --- 這是bug嗎 ？？C#代碼如下：            XmlDocument mydoc = new XmlDocument();            mydoc.Load(@"d:\hibernate.cfg.xml");            //XmlNode node = mydoc.DocumentElement;//移到config節點             //node = node.FirstChild;//移到database子節點             //node = node.FirstChild;//移到server子節點             //node = node.NextSibling;//移到sa子節點            //node = node.NextSibling;//移到passowrd子節點             //node.InnerText = "sfadsfs";//修改內容            mydoc.Save(@"d:\hibernate.cfg.xml");//保存XML文件:<?xml version="1.0" encoding="utf-8"?><!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN""http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"[]><hibernate-configuration>  <session-factory>...  </session-factory></hibernate-configuration>
