P.S.到目前为止，我已经找到了使用xPath来获取元素的HTML敏捷包.

Hello, I want a simple html analyzer(in c#) which can get the contents of an html element. Let me explain: I want to download a page, get the contents of ".class1 .class2 #id1 div" and then display it to the user. Do you have any leads(besides System.Net.WebClient)?

P.S. So far I have found HTML agility pack which uses an xPath to get an element.

推荐答案

我认为jQuery可以从给定的html控件中获取所有信息.您可以通过ID/it的关联类从特定的Div/Table中获取InnerHtml内容.

假设您的HTML内容为，

Hi,

I think jQuery can get all the information from your given html control. you can get InnerHtml content from particular Div/Table through the ID/it''s Associated Class.

Suppose you have HTML content as ,

<div class="demo-container">
  <div class="demo-box">Demonstration Box</div>
</div>

然后您可以使用
提取内部Div

Then you can extract Inner Div using,

(' div.demo-container ').html();

('div.demo-container').html();

结果将是

And Result would be

<div class="demo-box">Demonstration Box</div>

(以上代码取自 jQuery [ ^ ])

但是，如果您已经有层次结构信息可以在html中导航，那么这是可能的.

希望我回答了您的查询，
谢谢

(Above code is taken from jQuery[^])

But this can be possible if you already have hierarchy information to navigate in the html.

Hope i answered your query,
Thanks

如果知道要查找的标签，则可以使用正则表达式解析文件.如果XmlDocument是XHTML，它也可以使用.

You can use regex to parse a file if you know the tags you''re looking for. XmlDocument also works, if its XHTML.
