  Hi Edwin_Pro_Net,

  You can use the following method to find all the  TD tag, and remove the content from the html.

  Then you can eliminate that.

  Please check the following code:

  private string RemoveTDTag(string result)
      {
          Regex chr = new Regex(@"<TD[^>]*>([^<])+</TD>", RegexOptions.IgnoreCase);
          for (Match m = chr.Match(result); m.Success; m = m.NextMatch())
          {
              result = result.Remove(groups[0].ToString());
          }
          return result;
      }

  Just a small changes in Bold,
  

  public class MyProvider : System.Web.Hosting.VirtualPathProvider
  {
      int i = 0;
      public static void AppInitialize()  
      {  
          MyProvider fileProvider = new MyProvider();
          System.Web.Hosting.HostingEnvironment.RegisterVirtualPathProvider(fileProvider);
      }
  
      public override bool FileExists(string virtualPath)
      {
          if (virtualPath.EndsWith("YourVirtualPath.aspx"))
              return true;
          else
              return Previous.FileExists(virtualPath);
      }
  
      public override System.Web.Hosting.VirtualFile GetFile(string virtualPath)
      {
          if (virtualPath.EndsWith("YourVirtualPath.aspx"))
          {
              string s = "http://www.bing.com/search?q=Searching+Text+Box+In+Bing+Site&go=&form=QBRE&qs=n";//Default
              if (HttpContext.Current.Application["url"] != null)
                  s = HttpContext.Current.Application["url"].ToString();
              HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(s);
              HttpWebResponse respons;
              respons = (HttpWebResponse)request.GetResponse();
              StreamReader reader = new StreamReader(respons.GetResponseStream());
              string contents = reader.ReadToEnd().Replace("<input", "<input runat=\"server\"");
              contents =  System.Text.RegularExpressions.Regex.Replace(contents,"<table",new System.Text.RegularExpressions.MatchEvaluator(ReplaceIds),System.Text.RegularExpressions.RegexOptions.IgnoreCase);
              return new MyVirtualFile(virtualPath, contents);
          }
          else
              return Previous.GetFile(virtualPath);
  
      }
      private string ReplaceIds(System.Text.RegularExpressions.Match input)
      {
          i++;
          return "<table id=\"jjj"+i+"\" runat=\"server\"";
      }
  
  }

  There is no Literal in HTML instead it is ASP.NET Control which content paste as it is as I know.
