c# - 通过 html 敏捷包从 wiki 获取数据

Question

我正在尝试通过 HTML 敏捷包从 wiki 主页（https://en.wikipedia.org/wiki/Main_Page ）获取数据。您能否帮助 Xpath 查询以获取与“您知道...”表相关的所有数据。它实际上包含元素列表，我想得到它们。

<h2 id="mp-dyk-h2" style="clear:both; margin:0.5em; background:#cef2e0; font-family:inherit; font-size:120%; font-weight:bold; border:1px solid #a3bfb1; color:#000; padding:0.2em 0.4em;"><span class="mw-headline" id="Did_you_know...">Did you know...</span></h2>
<div id="mp-dyk" style="padding:0.1em 0.6em 0.5em;">
<div class="dyk-img" style="float: right; margin-left: 0.5em;">
<div class="thumbinner mp-thumb" style="background: transparent; border: none; padding: 0; max-width: 180px;">

</div>
<ul><li>... that the <b><a href="/wiki/Carron_Bridge_(River_Spey)" title="Carron Bridge (River Spey)">Carron Bridge</a></b> <i>(pictured)</i> was the last cast-iron railway bridge to be built and used in Scotland?</li>

<li>... that an inscription at the <b><a href="/wiki/Tomb_of_Isa_Khan" title="Tomb of Isa Khan">tomb of Isa Khan</a></b> claims that it is an "asylum of paradise"?</li>

我对此进行了研究，但我需要知道的信息范围如此之大，任务如此之少

IEnumerable<string> listItemHtml = htmlDoc.DocumentNode.SelectNodes(
    @"//div[@class='Wiki']/div[@class='Did_you_know...']/ul/li")
    .Select(li => li.OuterHtml);
use this for search
