python - Xpath 选择 标签后的数据

Question

我有这个html:

<div class="sys_key-facts">
  <p>
   <strong>Full-time </strong>1 year<br>
   <strong>Part-time</strong> 2 years
  </p>
</div>

我想获取Part-time(After Part-time)的值，即:

2 years</p>

我的 Xpath 代码是:

//div[@class="sys_key-facts"]/p[strong[contains(text(), "Part-time")]][preceding-sibling::br]/text() 

但这返回空。请让我知道我错在哪里。谢谢

Answer 1

问题是 p[preceding-sibling::br]表示该段落有换行兄弟，而 br实际上是p的 child - 不是 sibling

因此您可以将 XPath 更新为

//div[@class="sys_key-facts"]/p[strong[contains(text(), "Part-time")] and br]/text()[last()]

或者尝试下面的 XPath 来获取所需的输出:

//div[@class="sys_key-facts"]//strong[.="Part-time"]/following-sibling::text()
