Question

<div class="countdownHolder"> <span class="countMinutes"> <span class="position"> <span class="digit static" style="top: 0px; opacity: 1; transition: 350ms ease;">0</span> </span> <span class="position"> <span class="digit static" style="top: 0px; opacity: 1; transition: 350ms ease;">0</span> </span> </span> <span class="countDiv countDiv0">:</span> <span class="countSeconds"> <span class="position"> <span class="digit static" style="top: 0px; opacity: 1; transition: 350ms ease;">4</span> </span> <span class="position"> <span class="digit static" style="top: 0px; opacity: 1; transition: 350ms ease;">0</span> </span> </span> </div> 

我試着去閱讀的價值在閱讀HTML類此圖像中強調的，不太清楚如何從我在哪裏得到它。

功能

private HtmlElement[] GetElementsByClassName(WebBrowser wb, string tagName, string className) 
{ 
    var l = new System.Collections.Generic.List<HtmlElement>(); 

    if (wb != null && wb.Document != null) 
    { 
     var els = wb.Document.GetElementsByTagName(tagName); 
     foreach (HtmlElement el in els) 
     { 
      if (el.GetAttribute("className") == className) 
      { 
       l.Add(el); 
      } 
     } 
    } 

    return l.ToArray(); 
} 

IM如何調用它，它似乎找到countdownHolder類

var countdownHolder = GetElementsByClassName(_webBrowser, "div", "countdownHolder"); 
if (countdownHolder.Length != 0) 
{ 

} 

Answer 1

我不知道答案，但我建議的策略：

var countdownHolder = GetElementsByClassName(_webBrowser, "div", "countdownHolder"); 
foreach (var element in countdownHolder.ToList()) 
{ 
    // inspect element here 
} 

GetElementsByClassName工程。

已更新：

下面應該給你你想要的。 element

UPDATE的

foreach (var element in countdownHolder) 
{ 
    var item1 = element.InnerText; //or 
    var item2 = element.OuterText; //both give the same answer here 
    // do something 
} 

一般而言，查看屬性2：

實際結構是：

<div class='countdownHolder'> 
    <span class='countMinutes'> 
     <span class='position'> 
      <span class='digit static' style='top: 0px; opacity: 1; transition: 350ms ease;'> 
       0 
      </span> 
     </span> 
     <span class='position'> 
      <span class='digit static' style='top: 0px; opacity: 1; transition: 350ms ease;'> 
      0 
      </span> 
     </span> 
    </span> 
    <span class='countDiv countDiv0'> 
     : 
    </span> 
    <span class='countSeconds'> 
     <span class='position'> 
      <span class='digit static' style='top: 0px; opacity: 1; transition: 350ms ease;'> 
       4 
      </span> 
     </span> 
     <span class='position'> 
      <span class='digit static' style='top: 0px; opacity: 1; transition: 350ms ease;'> 
       0 
      </span> 
     </span> 
    </span> 
</div> 

嵌入文本給出了分，秒與:作爲分隔符。在這個例子中00:40。有了額外的空間：0 0 : 4 0

現在您只需要簡單的字符串處理。你可以用各種方法做到這一點。 string time = element.InnerText.Replace(" ", "");將刪除空格。然後有多種不同的方式來處理結果min:sec結構
