How to use HTML Agility pack

I have html code below:

<div><span class="help">This is text.</span>Hello, this is text.</div>
<div>I have a question.<span class="help">Hi</span></div>

Now, I want to remove text which is between <span class="help"></span> using C#. So, I want to leave only

<div>Hello, this is text.</div>
<div>I have a question.</div>

Anyone has any idea?

You should use Html Agility Pack to work with html.

string text = @"<div><span class=""help"">This is text.</span>Hello, this is text.      </div>
                <div>I have a question.<span class=""help"">Hi</span></div>";
HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(text);
var nodes = doc.DocumentNode.SelectNodes("//span[@class='help']");
foreach( HtmlNode node in nodes)
{
   node.Remove();
} 
String result = doc.DocumentNode.InnerHtml;
