c# 取出特定标签的内容 去除html标签

Match match = Regex.Match(x, "(?<=(<p[.\s\S]*?>))[.\s\S]*?(?=(</p>))", RegexOptions.Multiline | RegexOptions.Singleline);
            MatchCollection m=Regex.Matches(x, "(?<=<p[.\s\S]*?>)[.\s\S]*?(?=</p>)", RegexOptions.Multiline | RegexOptions.Singleline);
            while (match.Success)
            {
                Console.WriteLine(match.Value);
                match = match.NextMatch();
            }

取出p标签的内容，就是下一个的时候，还会带着<p>，好像有些奇怪

tem_description = Regex.Replace(tem_description, "<[^>]+>", "");
                        tem_description = Regex.Replace(tem_description, "&[^;]+;", "");
