使用HTMLAgilityPack提取特定的HTML文本

Question

<table class="result" summary="Summary Description."> 
<tbody> 
<tr> 
    <th scope="col" class="firstcol">Column 1</th> 
    <th scope="col">Column 2</th> 
    <th scope="col">Column 3</th> 
    <th scope="col" class="lastcol">Column 4</th> 
</tr> 
<tr class="even"> 
    <td class="firstcol">Text 1</td> 
    <td>Text 2</td> 
    <td>4Text 3</td> 
    <td class="lastcol">Text 4</td> 
</tr> 
</tbody></table> 

HTML Im感興趣的部分看起來像這樣。我想要文本1，文本2，文本3和文本4.使用HTMLAgilityPack，我如何提取數據？我谷歌和檢查這個網站，但沒有找到一些完全符合我的情況。

 if (htmlDoc.DocumentNode != null) 
     { 
      foreach (HtmlNode text in htmlDoc.DocumentNode.SelectNodes(???) 
      { 
       ??? 
      } 
     }

試試這個：

 var html = @"<table class=""result"" summary=""Summary Description.""> <tbody> <tr>  <th scope=""col"" class=""firstcol"">Column 1</th>  <th scope=""col"">Column 2</th>  <th scope=""col"">Column 3</th>  <th scope=""col"" class=""lastcol"">Column 4</th> </tr> <tr class=""even"">  <td class=""firstcol"">Text 1</td>  <td>Text 2</td>  <td>4Text 3</td>  <td class=""lastcol"">Text 4</td> </tr> </tbody></table>"; 
     var doc = new HtmlDocument(); 
     doc.LoadHtml(html); 
     var textNodes = doc.DocumentNode.SelectNodes(@"//tr[@class='even']/td/text()").ToList(); 
     foreach(var textNode in textNodes) 
     { 
      Console.WriteLine(textNode.InnerText); 
     }
