隨着HtmlAgility包，我怎麼能得到<td valign="top" class="m92_h_bigimg">和他的收盤<td>之間的數據。我試着用這個代碼不使用HtmlAgility-pack，這個工程，但它發現第一個</td>並關閉。所以代碼是不正確的。我讀過HtmlAgility-pack是這類問題的最佳解決方案。讀取數據開始到結束

public static string[] GetStringInBetween(string strBegin, string strEnd, string strSource, bool includeBegin, bool includeEnd) 
{ 
    string[] result = { "", "" }; 
    int iIndexOfBegin = strSource.IndexOf(strBegin, StringComparison.Ordinal); 

    if (iIndexOfBegin != -1) 
    { 
     int iEnd = strSource.IndexOf(strEnd, iIndexOfBegin, StringComparison.Ordinal); 

     if (iEnd != -1) 
     { 
      result[0] = strSource.Substring(iIndexOfBegin + (includeBegin ? 0 : strBegin.Length), iEnd + (includeEnd ? strEnd.Length : 0) - iIndexOfBegin); 

      if (iEnd + strEnd.Length < strSource.Length) 
         result[1] = strSource.Substring(iEnd + strEnd.Length); 
     } 
    } 
    return result; 
}

我該怎麼做？

例如對於這個特定的搜索正則表達式可能是一個更簡單的解決方案，在AgilityPack中使用SelectNodes（「...」）;-) – jwillmer 2012-03-07 09:45:07

HtmlAgilityPack.HtmlDocument htmlDoc = new HtmlAgilityPack.HtmlDocument(); 
htmlDoc.LoadHtml(html); 
var str = htmlDoc.DocumentNode 
    .Descendants("td") 
    .Where(x => x.Attributes["class"] != null && x.Attributes["class"].Value == "m92_h_bigimg") 
    .Select(x => x.InnerHtml) 
    .First();

thx你很LB – senzacionale 2012-03-07 12:44:03

的HtmlAgilityPack支持標準XPath查詢，所以我認爲你可以這樣做：

foreach (var node in doc.DocumentElement.SelectNodes("//td[@class='m92_h_bigimg']")) 
{ 
    // Do work on your node. 
}

...其中doc是你的HtmlDocument
