我有这个:
li.current+li>a
但是我只有 XPath 的基本知识。 我需要它用于 AutoPager Firefox 扩展。
我也想只获得第一场比赛。
最佳答案
如果您的li属于很多类，那么...
//li[contains(concat(' ',normalize-space(@class),' '),' current ')]/following-sibling::*[1]/self::li/a
为了清楚起见，这里将同一件事分成多行:
//li[contains(
concat(' ',normalize-space(@class),' '),
' current '
)
]/following-sibling::*[1]/self::li/a

我用Online XPath 2 evaluator测试了它使用以下 XML:

您应该注意，您作为输入链接到的页面 - http://forums.whirlpool.net.au/forum-replies.cfm?t=1543353&p=26 - 是 HTML，不是 XML:
- 其文档类型声明适用于 HTML 4.01
- 文档包含未封闭的标签，例如
<br>这必须是<br />
...因此您在使用它作为 XPath 评估的输入时可能会遇到问题。
关于css - 包含类、子级和相邻同级选择器的 CSS 选择器的等效 XPath 是什么？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/5338933/
