在.net中我想用正则获得这段html中的介绍，最终得到的这句话应该是：
何许人常用诗句描写画中之景，抒发自己的情愫，所题诗句透出清新的书卷气。在瓷板的左上角题诗“豪气冲寒雪浪开，骑驴蹴踏小桥来，梅花岭上馨香满，折得旋归助酒醅”。其书法行笔稳健，转折圆浑，顿挫变化明显，字与字之间少连笔，却有绵延直下、一气呵成之势。整个瓷板充分展现了瓷版画浅淡柔和、精美素雅的文人画风格，这种瓷画既蕴含着深厚的思想境界，又显示出非凡的艺术魅力。

用正则怎么处理。我用Regex.Replace(result, @"[^\u4e00-\u9fa5]", "");这样替换，结果这段话里面的逗号，分号，句号都没有了。求大神写个正则。

        static void Main(string[] args)
        {
            string s =File.ReadAllText("test.txt",Encoding.Default);
            string reg = @"sa"">(.+?)<";
            MatchCollection mc = Regex.Matches(s, reg);
            StringBuilder sb = new StringBuilder();
            foreach (Match item in mc)
            {
                sb.Append(item.Groups[1].ToString());
            }
            Console.WriteLine(sb.ToString());
            Console.ReadKey();
        }

Regex.Replace(s, "<[^>]*>", "");

引用 1 楼 zijiang001 的回复:

Regex.Replace(s, "<[^>]*>", "");

我的是Regex.Replace(s, "<[^>]*?>", "");这是去除<>里的内容

引用 2 楼 zhouxiulu 的回复:

        static void Main(string[] args)
        {
            string s =File.ReadAllText("test.txt",Encoding.Default);
            string reg = @"sa"">(.+?)<";
            MatchCollection mc = Regex.Matches(s, reg);
            StringBuilder sb = new StringBuilder();
            foreach (Match item in mc)
            {
                sb.Append(item.Groups[1].ToString());
            }
            Console.WriteLine(sb.ToString());
            Console.ReadKey();
        }

太麻烦，还有foreach。
