使用Web浏览器控件按类名获取div的内容? [英] Get the content of a div by class name using Web Browser control?

问题描述

我有一个带有 webBrowser1 控件的表单，该表单用于加载HTML行中包含以下行的页面:

I have a form with webBrowser1 control that is used to load a page that contains in its HTML part the following line:

 ...
 <div class="cls">
 Hello World !
 </div>

我需要获取 div 元素的 innerText .我尝试了以下方法:

I need to get the innerText of the div element. I tried the following:

 string result = "";
 foreach (HtmlElement el in webBrowser1.Document.GetElementsByTagName("div"))
                if (el.GetAttribute("class") == "cls")
                {
                    result = el.InnerText;
                }

但是上面的代码似乎不起作用，并且根据 表示，

But the code above doesn't seem to work, and according to Solution 1 for a similar question on another website, it is stated that

引起我注意的第一件事是:< div class ="thin"> 没有定义 div 元素的名称，它定义了CSS样式班级.而是使用属性名称(或同时使用两者)，例如:< div class ="thin" name ="thin"> .

First thing which caught my eye is: <div class="thin"> does not define the name of the div element, it defines its CSS style class. Instead, use the attribute name (or both), for example: <div class="thin" name="thin">.

如果仅具有 class 属性，如何获取 div 元素的 innerText ?

How can I get the innerText of the div element, if there is a class attribute only?

任何帮助将不胜感激.

推荐答案

您应使用 ClassName 而不是 class :

 if (el.GetAttribute("className") == "cls") { … }
