C＃，Html Agility，选择div标签中的每个段落 [英] C#, Html Agility, Selecting every paragraph within a div tag

问题描述

 < div id =body_text>如何选择div标签中的每个段落？ 
< p>嗨< / p> 
< p>请帮助我< / P> 
< p> Thankyou< / P> 
  

我在程序中下载并引用了Html Agility，我需要的是段落。可能有不定数量的段落，并且有不同的div标签加载，但我只需要body_text内的内容。然后我认为这可以存储为一个字符串，然后我想写入一个.txt文件供以后参考。谢谢。

解决方案

您的案件的有效XPATH是 // div [@ id ='body_text' ] / p

  foreach（HtmlNode node in yourHTMLAgilityPackDocument.DocumentNode.SelectNodes（// div [ @ b = b）
 {
 string text = node.InnerText; //这就是你正在寻找的文本
} 
  

How can I select every paragraph in a div tag for example.

<div id="body_text">
<p>Hi</p>
<p>Help Me Please</P>
<p>Thankyou</P>

I have got Html Agility downloaded and referenced in my program, All I need is the paragraphs. There may be a variable number of paragraphs and there are loads of different div tags but I only need the content within the body_text. Then I assume this can be stored as a string which I then want to write to a .txt file for later reference. Thankyou.

解决方案

The valid XPATH for your case is //div[@id='body_text']/p

foreach(HtmlNode node in yourHTMLAgilityPackDocument.DocumentNode.SelectNodes("//div[@id='body_text']/p")
{
  string text = node.InnerText; //that's the text you are looking for
}
