Exactement une table en utilisant scrapysharp

Question

J'ai des données d'un site Web que je suis en train de gratter. Les données ressemblent à ci-dessous. Comment puis-je extraire le table en utilisant scrapysharp?

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 

using HtmlAgilityPack; 
using ScrapySharp.Extensions; 
using ScrapySharp.Network; 

namespace Scrape 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      ScrapingBrowser browser = new ScrapingBrowser(); 

      //set UseDefaultCookiesParser as false if a website returns invalid cookies format 
      //browser.UseDefaultCookiesParser = false; 

      WebPage homePage = browser.NavigateToPage(new Uri("http://www.nasdaq.com/earnings/earnings-calendar.aspx")); 
      var divs = homePage.Html.CssSelect("div"); //all div elements 
      var trs = homePage.Html.SelectNodes("//div") 
       .Where(n => !String.IsNullOrEmpty(n.GetAttributeValue("class")) 
       //(n.GetAttributeValue("class") == "genTable") 
       );      
     } 
    } 
} 

Ceci est la partie pertinente du html:

<div class="clearB"></div> 

     <div class="genTable"> 
      <div id="_confirmed" > 
       <!--<div class="floatL"> 
        <h3>Earnings Date - Confirmed by Zacks</h3> 
       </div> 
       <div class="clearB"></div> 
       <br />--> 

       <div id="two_column_main_content_pnlInsider"> 


          <table class="USMN_EarningsCalendar" id="ECCompaniesTable" border="0"cellpadding="0" cellspacing="0">

j'imagine quelque chose comme ce code

var hw = new HtmlWeb(); 
     doc = hw.Load("http://www.nasdaq.com/earnings/earnings-calendar.aspx"); 

     foreach (HtmlNode row in doc.DocumentNode.Descendants("table").FirstOrDefault(_ => _.Id.Equals("ECCompaniesTable")).Descendants("tr")) 
     { 
      Console.WriteLine(row.InnerText); 
     }
