Unable to locate element inside a table using xpath with selenium

I want to click on a button inside my table each row has a update button I want to click on a specfic button inside my table.
Here is a what my table looks like:
<table _ngcontent-vhp-c82="" datatable="" id="dtOptionsComments" class="display table table-striped table-bordered dt-responsive dataTable dtr-inline" aria-describedby="dtOptionsComments_info" style="width: 100%;" width="100%">

Here is my code trials:
IWebElement btnUpdate = _driver.FindElement(By.XPath("//*[update-comment-id='" + commentAction.GetLastQuoteInsertId().ToString() + "']"));
btnUpdate.Click();
I have validated that the function GetLastQuoteInsertId returns the proper value
Why is my xPath selector wrong how can I fix it thank you for your help.

You were almost there. While considering a xpath the attribute_name should be always preceded by a # sign.
Additionally to make the xpath more canonical as the element is a <span> element you can mention //span to start the xpath.
Effectively, your line of code will be:
IWebElement btnUpdate = _driver.FindElement(By.XPath("//span[#update-comment-id='" + commentAction.GetLastQuoteInsertId().ToString() + "']"));
btnUpdate.Click();

I need help to implement XPath

I have the following email from amazon that is from temp-mail.org
Basically amazon has sent me a verification code after i signed up with an email from temp-mail.org. I would like to use XPath to scrape/extract that Verification code and ignore everything else in the email and save it as a variable.
Here is the source for the email:

As you can see, the code is

Now how would i go about using XPath, or anything else (I have an open mind), to save that specific Code which will change everytime i run the program, to a variable called "verifyCode" or whatever variable name you please. Thank you!
Using inspect element, i have found the XPath which is:
//*[#cellspacing='0']/tbody/tr/td/table/tbody/tr[2]/td/p[2]
but when i use
var codeverify = driver.FindElement(By.XPath("//[#cellspacing='0']/tbody/tr/td/table/tbody/tr[2]/td/p[2]/text()"));
it tells me XPath is invalid

You can use HtmlAgilityPack nugget package and use below code. Input.html is the HTML which you mentioned in your question.
var htmlDoc = new HtmlDocument();
htmlDoc.LoadHtml(File.ReadAllText("Input.html"));
var element = htmlDoc.DocumentNode.Descendants()
.Where(x => x.InnerText == "To verify your identity, please use the following code:")
.ToList()
.FirstOrDefault();
while (element.NextSibling.Name != "p")
element = element.NextSibling;
var code= element.NextSibling.InnerText;

Unable to locate input element under div in Selenium

I am trying to located input element "mpcname" in js file which is under div and table elements.
The code I have written to locate the element is as follows but is not detecting the Input element with the name mpcName in it.
Driver.FindElement(By.XPath(".//input[contains(.,'mpcName')]"));
The HTML code looks like below.
<div enable-tooltips="" class="ng-scope">
<form name="InstanceDetailForm" ng-submit="doApply()" novalidate="" class="ng-pristine ng-invalid ng-invalid-required ng-valid-unnamed ng-valid-maxlength ng-valid-not-integer">

With xpath ".//input[contains(.,'mpcName')]" you are actually looking for an <input> element with text mpcName. mpcName is actually the id (and name and ng-model) attribute. You can use
Driver.FindElement(By.Id("mpcName"));
Or
Driver.FindElement(By.Name("mpcName"));

following code may be helpful
Driver.FindElement(By.XPath(".//input[contains(#id,'mpc')]");
Driver.FindElement(By.XPath(".//input[contains(#class,'ng-pris')]");

Parsing HTML content with C# Parser

I have the following HTML file, I want to get each H2 (Standard (Flexible Rate).. and Executive (Flexible Rate) ... with the Room Only , Breakfast Included .
Then push the Room Only and Breakfast Include with 2 Prices of each into objects where I have Standard along with 2 prices from Room Only and Breakfast Included, and the same for Executive
I tried Fizzler with AgilityPack however, I couldn't get the correct results, could you please suggest me an idea or one good parser for this case? Thanks

Here you go with a quick and dirty approach:
class RoomInfo
{
public String Name { get; set; }
public Dictionary<String, Double> Prices { get; set; }
}
private static void HtmlFile()
{
List<RoomInfo> rooms = new List<RoomInfo>();
HtmlDocument document = new HtmlDocument();
document.Load("file.txt");
var h2Nodes = document.DocumentNode.SelectNodes("//h2");
foreach (var h2Node in h2Nodes)
{
RoomInfo roomInfo = new RoomInfo
{
Name = h2Node.InnerText.Trim(),
Prices = new Dictionary<string, double>()
};
var labels = h2Node.NextSibling.NextSibling.SelectNodes(".//label");
foreach (var label in labels)
{
roomInfo.Prices.Add(label.InnerText.Trim(), Convert.ToDouble(label.Attributes["precio"].Value, CultureInfo.InvariantCulture));
}
rooms.Add(roomInfo);
}
}
The rest is up to you! ;-)

How do I scrape information off ASP.NET websites when paging and JavaScript links are being used?

I have been given a staff list which is supposed to be up to date but it doesn't match an intranet People Finder which is written in ASP.NET.
As the information is sensitive I am not able to access the database the People Finder is using so the only way I can get at the information is by scraping the structure starting at the top brass at the top and then going through each tier in turn.
Each person has a Staff number which then forms the URL http://intranet/peoplefinder/index.aspx?srn=ABC1234 and then all the people who report to them are listed underneth in the format <a id="gvEmployees_ctl03_lnkFullName" href="index.aspx?srn=ABC4321" target="_self"> where each URL indicates the Staff number and provides a link to their team.
The trouble arises when the teams are big as paging is implemented in the GridView with an URL such as 2.
How would I scrape this page, capture the SRN and other details along with the people who report to the person on all pages of the GridView then loop through each reportee and do the same process until the whole list is complete?

You could post a variable to the HTML page to go through the paging.
string lcUrl = "http://www.mysite.com/page.aspx";
HttpWebRequest loHttp =
(HttpWebRequest) WebRequest.Create(lcUrl);
// *** Send any POST data
string lcPostData =
"gvEmployees=" + HttpUtility.UrlEncode("Page$2");
loHttp.Method="POST";
byte [] lbPostBuffer = System.Text.
Encoding.GetEncoding(1252).GetBytes(lcPostData);
loHttp.ContentLength = lbPostBuffer.Length;
Stream loPostData = loHttp.GetRequestStream();
loPostData.Write(lbPostBuffer,0,lbPostBuffer.Length);
loPostData.Close();
HttpWebResponse loWebResponse = (HttpWebResponse) loHttp.GetResponse();
Encoding enc = System.Text.Encoding.GetEncoding(1252);
StreamReader loResponseStream =
new StreamReader(loWebResponse.GetResponseStream(),enc);
string lcHtml = loResponseStream.ReadToEnd();
loWebResponse.Close();
loResponseStream.Close();
Then parse out the data you need from the string.
--EDIT--
Here is what I would try (something similar) where all of the post data is sent:
string lcPostData =
"__EVENTTARGET" + HttpUtility.UrlEncode("gvEmployees"); &
"__EVENTARGUMENT" + HttpUtility.UrlEncode("Page%242"); &
"__VIEWSTATE" + HttpUtility.UrlEncode("<Value of _Viewstate>");

You open the fiddler and open the second page of asp.net website table.Go to webforms tab in Fiddler for that particular page session and check in the body what are the variables are posting.Concat all variables in same sequence format and post data using HttpWebRequest.
In my case it was:
string PostData = "__EVENTTARGET="
+ HttpUtility.UrlEncode("ctl00$ContentPlaceHolder2$grdDirectory")
+ "&"
+ "__EVENTARGUMENT="+HttpUtility.UrlEncode("Page$2")
+ "&"
