Answer 1

(?is)<td[^>]*?>\s*(<div[^>]*?>)?(.*?)(</div>)?\s*</td>

Answer 2

不只  <div class="consumeBizNo">2012102800001000310009864627 </div> </td>一个啊，还有其他那，其他怎么做啊？其他的又不一样，

Answer 3

 string html = System.IO.File.ReadAllText(@"C:\1.txt", Encoding.GetEncoding("GB2312"));
            string pattern1 = @"(?is)(?<=<td\s*class=""[^""]*?"">).*?(?=</td>)";
            string pattern2 = @"(?is)<(div|ul)[^>]*?>\s*(<li[^>]*?>)?(.*?)(</li>\s*)?</\1>";
            List<string> list1 = new List<string>();
            List<string> list2 = new List<string>();
            foreach (System.Text.RegularExpressions.Match m in System.Text.RegularExpressions.Regex.Matches(html, pattern1))
            {
                list1.Add(m.Value);
            }
            string ss = "";
            foreach (string l in list1)
            {                if (Regex.IsMatch(l, pattern2))
                {
                    ss = Regex.Match(l, pattern2).Groups[3].Value;
                }
                else
                    ss = l;
                list2.Add(ss);
            }
            list2.ForEach(x => Console.WriteLine(x)); 其余的自行处理

Answer 4

这儿有两个方法。。你可以试试。 全部封装好了。不用导入任何东西。直接拷进去引用就行了   public static string NoHTML(string Htmlstring)
    {        //删除脚本        Htmlstring = System.Text.RegularExpressions.Regex.Replace(Htmlstring, @"<script[^>]*?>.*?</script>", "", System.Text.RegularExpressions.RegexOptions.IgnoreCase);        //删除HTML        Htmlstring = System.Text.RegularExpressions.Regex.Replace(Htmlstring, @"<(.[^>]*)>", "", System.Text.RegularExpressions.RegexOptions.IgnoreCase);        Htmlstring = System.Text.RegularExpressions.Regex.Replace(Htmlstring, @"([\r\n])[\s]+", "", System.Text.RegularExpressions.RegexOptions.IgnoreCase);        Htmlstring = System.Text.RegularExpressions.Regex.Replace(Htmlstring, @"-->", "", System.Text.RegularExpressions.RegexOptions.IgnoreCase);        Htmlstring = System.Text.RegularExpressions.Regex.Replace(Htmlstring, @"<!--.*", "", System.Text.RegularExpressions.RegexOptions.IgnoreCase);        Htmlstring = System.Text.RegularExpressions.Regex.Replace(Htmlstring, @"&(quot|#34);", "\"", System.Text.RegularExpressions.RegexOptions.IgnoreCase);        Htmlstring = System.Text.RegularExpressions.Regex.Replace(Htmlstring, @"&(amp|#38);", "&", System.Text.RegularExpressions.RegexOptions.IgnoreCase);        Htmlstring = System.Text.RegularExpressions.Regex.Replace(Htmlstring, @"&(lt|#60);", "<", System.Text.RegularExpressions.RegexOptions.IgnoreCase);        Htmlstring = System.Text.RegularExpressions.Regex.Replace(Htmlstring, @"&(gt|#62);", ">", System.Text.RegularExpressions.RegexOptions.IgnoreCase);        Htmlstring = System.Text.RegularExpressions.Regex.Replace(Htmlstring, @"&(nbsp|#160);", " ", System.Text.RegularExpressions.RegexOptions.IgnoreCase);        Htmlstring = System.Text.RegularExpressions.Regex.Replace(Htmlstring, @"&(iexcl|#161);", "\xa1", System.Text.RegularExpressions.RegexOptions.IgnoreCase);        Htmlstring = System.Text.RegularExpressions.Regex.Replace(Htmlstring, @"&(cent|#162);", "\xa2", System.Text.RegularExpressions.RegexOptions.IgnoreCase);        Htmlstring = System.Text.RegularExpressions.Regex.Replace(Htmlstring, @"&(pound|#163);", "\xa3", System.Text.RegularExpressions.RegexOptions.IgnoreCase);        Htmlstring = System.Text.RegularExpressions.Regex.Replace(Htmlstring, @"&(copy|#169);", "\xa9", System.Text.RegularExpressions.RegexOptions.IgnoreCase);        Htmlstring = System.Text.RegularExpressions.Regex.Replace(Htmlstring, @"&#(\d+);", "", System.Text.RegularExpressions.RegexOptions.IgnoreCase);        Htmlstring.Replace("<", "");        Htmlstring.Replace(">", "");        Htmlstring.Replace("\r\n", "");        Htmlstring = HttpContext.Current.Server.HtmlEncode(Htmlstring).Trim();        return Htmlstring;    }    public string StripHTML(string strHtml)
