如何获取 html 页面中两个字符串之间的数据
How to get the data in between two strings in a html page
我有几个 html 页面是这样的：
标题
简介
Table 的内容：
选项1。艺术
选项2。运动
选项3。跳舞
选择说明
选项1。艺术
一个。水彩
描述
b.油画
描述
C。丙烯画
描述
选项2。运动
一个。篮球
描述
b.蟋蟀
描述
C。足球
描述
选项3。舞蹈
一个。霹雳舞
所有这些内容都以不同的 html 格式保存在每个 html 页面中。我想在每个页面的运动选项下收集整个文本。 （无论如何，除了弄清楚 xpaths 之外，我还能实现这个吗，因为每个 html 页面的结构都不同）。
请帮忙。谢谢你。

好吧，我会在这里使用 jQuery .text()，因为它似乎完全符合您的要求（仅显示所有 selected 节点的文本内容）。
除此之外，select使用正确的元素是一件简单的事情，所以我们确实需要知道 "section" 到 select 是什么。可能是这样的：
$("P:contains('option 2')").nextUntil("p:contains('option 3')").text()
console.log($("P:contains('option 2')").nextUntil("p:contains('option 3')").text())
