HTMLAgility pack C# unclosed colgroup tag

I have a string (HTML) being posted to server side and then it is validated using HTMLAgility pack. In the HTML there is an unclosed colgroup tag.
After sanitizing, the closing colgroup tag appears but right between closing "tbody" and "table" tag

I tried setting "OptionFixNestedTags" flag to true. I still get the same result.

I tried various options from HTMLAgility pack and setting them true. This didn't work.
OptionFixNestedTags = true;
OptionAutoCloseOnEnd = true;
There is a nice Nuget package which sanitizes the html. The problem which I faced was tackled here -> HtmlSanitizer
Hope this helps.

for some reason, i want to use this ascx for example to send data to the server side. however, i have problem because when using asp.net button, the event doesnot fire back. can anyone give me more advice to accomplish this current condition. or should i use bootstrap modal rather than jquery mobile ui ? and how to use ascx as modal ? thank you very much :)
PS: i am using
<link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.css" />
<script src="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.js"></script>

you have to try bootstrap Modal like

How to save necessary information of HTML file to string variable

A HTML file is generated by Android MobileBiz Pro invoice app. I'm trying to make software for print HTML based invoice via receipt printer
I need to save necessary information of HTML file to string variable as mentioned below. I tried using IndexOf method. but it's not working for me. How can I get this information using visual c#?
string subtotal = 2,976.00;
string total = 2,976.00;
string payment= 2,760.00;
string balance= 216.00;
This is an example of the HTML code:
<tr><td align="right" colspan="3">Subtotal</td><td align="right">2,976.00</td></tr><tr><td align="right" colspan="3"><b>TOTAL</b></td><td align="right"><b>2,976.00</b></td></tr><tr><td align="right" colspan="3">Less Payment</td><td align="right">2,760.00</td></tr><tr class="total"><td align="right" colspan="3"><strong>Balance Due</strong></td><td align="right">216.00</td></tr>

You need an html parser, try this one http://htmlagilitypack.codeplex.com/
Load page into HtmlDocument
HtmlWeb htmlWeb = new HtmlWeb();
HtmlDocument htmlDocument = htmlWeb.Load("url");
Get table with specified Id
HtmlNode table = htmlDocument.DocumentNode.Descendants("table").SingleOrDefault(x => x.Id == "tableId");
Loop through nodes to find values
foreach(HtmlNode child in table.ChildNodes)
{
if (child.NodeType != HtmlNodeType.Text)
{
Console.WriteLine(child.Name);
}
}
More you can check here http://www.codeproject.com/Articles/691119/Html-Agility-Pack-Massive-information-extraction-f

You have to use parseHTML function of jquery and then loop through each element to get the values. Below is the working example (It can be more refined as per your need)
$(document).ready(function () {
var str = '<tr><td align="right" colspan="3">Subtotal</td><td align="right">2,976.00</td></tr><tr><td align="right" colspan="3"><b>TOTAL</b></td><td align="right"><b>2,976.00</b></td></tr><tr><td align="right" colspan="3">Less Payment</td><td align="right">2,760.00</td></tr><tr class="total"><td align="right" colspan="3"><strong>Balance Due</strong></td><td align="right">216.00</td></tr>';
var html = $.parseHTML(str);
$.each(html, function (index, element) {
if ($(this).find("td:first").html() == "Subtotal")
console.log($(this).find("td:last").html());
else if ($(this).find("td:first b").html() == "TOTAL")
console.log($(this).find("td:last b").html());
else if ($(this).find("td:first").html() == "Less Payment")
console.log($(this).find("td:last").html());
else if ($(this).find("td:first strong").html() == "Balance Due")
console.log($(this).find("td:last").html());
});
});

I need text which preserves Newline. All these text are getting combined into a single line. How to handle this? Below is my C# code
string text = File.ReadAllText(#"C:\a.txt",Encoding.UTF8);
Regex regex = new Regex("<[^>]+>");
text = regex.Replace(text, " ").Replace("( )+", Environment.NewLine).Replace(" ", "").Replace("’", "'").Replace("\r\n\r\n(\r\n)+", Environment.NewLine);
text = HttpUtility.HtmlDecode(text);
Console.WriteLine(text);

I would never use regex to parse HTML, instead, use the HtmlAgilityPack, you can do a lot of things just using simple XQuery/XPath, example:
HtmlDocument doc = new HtmlDocument();
doc.Load(#"C:\temp\stackoverflow\question23657841\question23657841\a.html");
foreach (HtmlNode node in doc.DocumentNode.SelectNodes("//p"))
{
Console.WriteLine(node.InnerHtml);
}
The output is:
UNITED STATES
SECURITIES AND EXCHANGE COMMISSION
WASHINGTON, D.C. 20549
<b> </b>
And simply switching the XQuery to //font you get this:
[X]
ANNUAL REPORT UNDER SECTION 13 OR 15(d) OF THE SECURITIES EXCHANGE ACT OF 1934
For the fiscal year ended <b><u>October 31, 2012</u></b>
[ ]
TRANSITION REPORT UNDER SECTION 13 OR 15(d) OF THE SECURITIES EXCHANGE ACT OF 1934
For the transition period from _________ to ________

Why not read File line by line File.ReadAllLines() does just that

Here is my brief code.Problem is my modal pop up is not displaying. I can trace by alret in alert i am getting 0; but modal pop up not displaying. Can anyone help me to resolve?

asp:ModalPopupExtender is a Server control.
If you want to show it you ave to post a server side Show() event; client side (javascript I mean) won't work.
If you need to work client side, using jQuery, you don't need a server side control: an hidden div set at the top of the window will be enough for you.

Set BehaviorID for modal popup extender..
<asp:ModalPopupExtender ID="MPE" runat="server" BackgroundCssClass="modalBackground"
PopupControlID="pnlGame" CancelControlID="imgCloseBtn" BehaviorID="PopUp"TargetControlID="btnHidden">
</asp:ModalPopupExtender>
Javascript:
<script type="text/javascript">
function ShowReport() {
var Asgn1 = document.getElementById("<%=ddlAssignments.ClientID%>").value;
var Assn1 = document.getElementById("<%=ddlAssessment.ClientID%>").value;
var Asgn2 = document.getElementById("<%=ddlAssignments1.ClientID%>").value;
var Assn2 = document.getElementById("<%=ddlAssessment1.ClientID%>").value;
alert(Asgn1);
if (Asgn1 == 0)
{
$find("<%=ModalPopupExtender1.BehaviorID%>").show();
return false;
}
}
