[解决办法]

C# code

 static void Main(string[] args)            {                string htmlStr = @"你的HTML代码">                        Regex re = new Regex(@"(?is)<h1[^>]+>[^<]+</h1>\s*<div[^>]+>\s*<h3[^>]+>[^<]+</h3>\s*<div[^>]+>[^>]*?</div>\s*<div[^>]+>.*?</div>.*?<div[^>]+>.*?</div>", RegexOptions.None);                htmlStr = re.Match(htmlStr).Value;               Console.WriteLine(htmlStr);               Console.ReadLine();            }//结果：就是你3楼的HTML
