通过ID获取div内容 [英] Get div content by id

问题描述

我有一个字符串，可以保存整个html文档.我想在具有特定ID的div中获取所有内容.例如:

I have a string that keeps entire html document. I would like to get all the content inside a div with specific id. For example:

<div id="myId" class = "myClass">
 <div class = "myClass">hello</div>
</div>

我需要id ="myId"标记与结束标记之间的内容. 有什么办法可以做到这一点?输出应为第二行.

I need the content between the tag with id="myId" and it's closing tag. Any way to achieve this? The output should be the second line.

推荐答案

干净正确的方法是通过HTML解析器，例如

The clean and correct way would be via an HTML parser, like HtmlAgilityPack:

string stringThatKeepsYourHtml = "<div id=....";
HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(stringThatKeepsYourHtml);
string whatUrLookingFor = doc.GetElementbyId("myId").InnerHtml;
