使用HTML敏捷包刪除表列

Question

我從使用C＃的網站爲我自己的網站抓取了一張表並將其加載到字符串中。有太多列，所以我想知道是否有一個簡單的方法來刪除一些，可能使用HTML敏捷包，但在C＃中，如果有必要。

字符串中的表看起來像這樣：

<table> 
     <tr> 
      <th scope="col">&nbsp; </th> 
      <th scope="col">&nbsp; </th> 
      <th scope="col">P </th> 
      <th scope="col">W </th> 
      <th scope="col">L </th> 
      <th scope="col">T </th> 
      <th scope="col">NR </th> 
      <th scope="col">Bat </th> 
      <th scope="col">Bowl </th> 
      <th scope="col">Pen </th> 
      <th scope="col">Pts </th> 
     </tr> 
     <tr>

我想刪除列8-10（蝙蝠，碗和筆）。我不確定從哪裏開始，所以任何指針都會有所幫助！

您需要遍歷每個tr，並從每個節點中刪除第8,9,10個節點的td節點。

bool first = true; 
foreach (HtmlNode row in doc.DocumentNode.SelectNodes("//tr")) 
{ 
    if (first) 
    { 
     row.RemoveChild(row.SelectSingleNode("th[10]")); 
     row.RemoveChild(row.SelectSingleNode("th[9]")); 
     row.RemoveChild(row.SelectSingleNode("th[8]")); 
     first = false; 
    } 
    else 
    { 
     row.RemoveChild(row.SelectSingleNode("td[10]")); 
     row.RemoveChild(row.SelectSingleNode("td[9]")); 
     row.RemoveChild(row.SelectSingleNode("td[8]")); 
    } 
}
