I need help to implement XPath

Question

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:

        </div>
      </div>
    </div>

As you can see, the code is

<p>451429</p>

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;
