我正在尝试从以下选项中选择所有li元素:

I'm trying to select all the li elements in from the following:

<div> <ul> <li class="third left"> ... </li> <li class="third left"> ... </li> </ul> </div>

我正在使用以下XPath查询，但这不会返回任何内容.

I'm using the following XPath query but this returns nothing.

Dim result As HtmlNodeCollection = htmlDoc.DocumentNode.SelectNodes("//li[@class='third left']")

对空格的属性是否有不同的对待?使用此工具，XPath可以正常工作.

Are attributes with spaces treated differently? Using this tool the XPath works correctly.

推荐答案

正如@SimonMourier所说，您的XPath是正确的.我建议您执行以下操作:

As @SimonMourier said, your XPath is correct. I suggest you doing the following:

• 发布整个HTML源，并告诉我们是从文件中加载还是直接从Web加载

• Posting the entire HTML source and telling us if you're loading it from a file or directly from the web

将htmlDoc.DocumentNode.OuterHtml的内容写入文本文件.如果您是从网络上加载HTML，则可能是 404 (找不到 )之类的东西；)

Writing in a text file the content of htmlDoc.DocumentNode.OuterHtml into a text file. If you're loading the HTML from the web, maybe you're getting a 404 (Not Found) or something ;)
