与web浏览器

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> 

我试着去阅读的价值在阅读HTML类此图像中强调的，不太清楚如何从我在哪里得到它。

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如何调用它，它似乎找到countdownHolder类

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

} 

Answer 1

我不知道答案，但我建议的策略：

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

GetElementsByClassName工程。

已更新：

下面应该给你你想要的。 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，查看属性2：

实际结构是：

<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> 

嵌入文本给出了分，秒与:作为分隔符。在这个例子中00:40。有了额外的空间：0 0 : 4 0

现在您只需要简单的字符串处理。你可以用各种方法做到这一点。 string time = element.InnerText.Replace(" ", "");将删除空格。然后有多种不同的方式来处理结果min:sec结构
