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 ;)
