如何使用c解析html文檔＃

我必須按如下方式解析文檔。我正在嘗試HtmlAgilityPack，但它非常複雜。我需要這個標籤內的文字：<td style="background: #36461f;color: #ffffff;font-weight: bold;padding: 2px;font-size: 12px;height: 25px;">Mac Bahsi</td>和兒童如何使用c解析html文檔＃

你可以使用類似的東西：

var document = new HtmlDocument(); 
document.LoadHtml(text); 
var tables = document.Descendants("table").ToList(); 
foreach (var table in tables) 
{ 
    var node = HtmlNode.CreateNode(table.InnerHtml); 

    var td = node.SelectNodes("//td[@style='background: #36461f;color: #ffffff;font-weight: bold;padding: 2px;font-size: 12px;height: 25px;'").FirstOrDefault(); 
    ... 
    var divs = node.SelectNodes("//div[@class='div1']").ToList(); 
    ... 
}

謝謝感興趣。但是，我無法理解「後代」。我添加這個命名空間「System.Xml.Linq」但沒有奏效。 –

此方法從HtmlNode類放置在HtmlAgilityPack命名空間中。 – Artem

對不起，但它不起作用。 Visual Studio查看缺少的參考。 HtmlAgilityPack名稱空間已附加。 –

我這樣做了。但這是一個很長的路。如果有更好的捷徑和更好的方法，請寫。

  HtmlWeb h = new HtmlWeb(); 
      HtmlDocument doc = h.Load(Server.MapPath("xml/htmlpage.html")); 
      HtmlNodeCollection n = doc.DocumentNode.SelectNodes("//html/body/table"); 

      string item; 
      string[] items; 
      string oran, oranadi; 
      int oran_id, secim; 
      for (int i = 1; i < n.Count + 1; i++) 
      { 
       HtmlNode ns = n[i - 1].SelectSingleNode(string.Format("//html/body/table[{0}]/tr[1]/td", i)); 
       HtmlNodeCollection nc = n[i-1].SelectNodes(string.Format("//html/body/table[{0}]/tr[2]/td[1]/div", i)); 
       Response.Write(string.Format("{0} --> {1}<br/>", i, ns.InnerHtml)); 
       for (int j = 1; j < nc.Count + 1; j++) 
       { 
        HtmlNode ncs = nc[j - 1].SelectSingleNode(string.Format("//html/body/table[{0}]/tr[2]/td[1]/div[{1}]", i, j)); 
        item = ncs.Attributes[2].Value.ToString(); 
        items = item.Split(';'); 
        oran_id = Convert.ToInt32(items[7].Replace("')", "")); 
        oranadi = items[6].ToString(); 
        secim = Convert.ToInt32(items[5]); 
        oran = items[4]; 

        Response.Write(string.Format("{0} --> {1} - {2} - {3} - {4} <br/>", j, secim, oran_id, oranadi, oran)); 
       } 
      }
