</div>

如何从上面的 HTML 中提取文本。 我尝试按照 XPath 提取文本

1. ‘//*[@class=“job-description”]’

2. //[@id=“main”]/div/div/div[1]/div[1]/div/div[2]/div[2]//text()

3. //[@id=“main”]//div[@class=“job-description”]/’
4. //div[@class=“job-description”]/p/text()
5. '//div[@class="job-description"]/following-sibling::node()/descendant-or-self::text()'

6.'//div[@class="job-description"]/p/descendant-or-self::text()'

但是没有得到输出 谁能告诉我如何抓取这些信息，因为它在类中有多个 {p}​​ 标签，(ul} 标签。

所以现在我很困惑如何获取信息。

提前致谢

您并不是很清楚您想要什么，但听起来您想要一个能为您提供所有文本节点的 XPath 查询。你可以这样做:

/descendant::text()
