Within HTML code, I am trying to extract an email address only if it is provided by the user. Here is a sample of the HTML: 

<div class="header">
 <div class="details">
   <span>
     <!-- Random description here which MAY contain an email address -->
   </span>
 </div>
</div>

I have managed to get to <span>by using HTML Agility Pack as follows: 

var getWeb = new HtmlWeb();
var pageHtml = getWeb.Load("website here");
IEnumerable<string> listItemHtml = pageHtml.DocumentNode.SelectNodes(
                    @"//div[@class='header']
                    /div[@class='details']
                    /span").Select(span => span.InnerText);

My next challenge is to search through this text and check if an email has been provided, which I am unable to figure out. Could someone please help me with this?

  • You **could** use a regexp but then you'd have the regexp as a second problem :) – Irwene Jul 27 '17 at 10:07
