检索< li>内的部分文本 [英] Retrieve parts of text inside <li>

问题描述

我有这样的HTML

<li class="in-ttl-b">(a) kanji; a Chinese character [ideograph]
    <ul class="list-data-b-in"><li class="text-jejp text-c"><span class="ex">漢字で書く</span></li><li class="text-jeen text-c">write in <i>kanji</i> [<i>Chinese characters</i>]</li></ul>
    <ul class="list-data-b-in"><li class="text-jejp text-c"><span class="ex">常用漢字</span></li><li class="text-jeen text-c"><i>Chinese characters</i> for everyday use (in Japan)</li></ul>
</li>

我怎么只能得到kanji; a Chinese character [ideograph]?

推荐答案

您可以通过选择第一个 text节点作为外部li元素的子元素来获得.例如，假设li和class="in-ttl-b"可以有多个实例:

You can get that by selecting the first text node that is child of the outer li element. For example, assuming there can be more than one instance of li with class="in-ttl-b" :

Dim lis = HTMLDoc.DocumentNode.SelectNodes("//li[@class='in-ttl-b']")
For Each li As HtmlNode in lis 
    'select the first text node in <li> :
    Dim txt = li.SelectSingleNode("text()[1]")
    Console.WriteLine(li.InnerText)
Next
