我的 Jsoup 解析代码再也找不到“价格”数据了-解网

问：

我正在解析一个网站的商品价格，在我的代码中我使用了：

val parseId : Elements = doc2.select("#PriceSection")
val spanSelected : Elements = parseId.select("span")
stringBuilder2.append(spanSelected)
val spanToString = stringBuilder2.toString()
for(char in spanToString){
    list2.add(char)
}
val newList2 = list2.toString()
val cutString2 = newList2.substring(75,105)

这已经工作了几个星期，但现在这似乎不起作用，除了我需要的那一点之外，我只是得到了其他所有东西。我不知道如何收集我需要的数据（HTML 代码的最后一行，在 span 类中）。我尝试了和的组合，但我无法弄清楚为什么 Jsoup 再也找不到文本了。:has:contains

以下是来自该网站的 HTML 代码：

过去发生的事情是，我可以阅读跨度类中的“£22,508.13”，但现在我不能（底部跨度类）。

我的代码查找一个名为“PriceSection”的类，然后在“PriceSection”内部查找以从内部获取所有跨度类。然后，我过滤掉我不需要的东西。

使用相同的代码，我现在得到一个单词“Relative”，它似乎来自包含我想要的信息的类之后的另一个 html 类。

为什么 Jsoup 现在找不到 span 类（包含价格），而它以前工作正常？

Android HTML Kotlin 解析 jsoup

事情停止工作是有原因的 - 要么是网站发生了变化，要么是你的代码发生了变化。您的代码是否包含您期望的所有 html？如果您打印（到屏幕或文件），它是否具有所有预期的 html？
您最近是否对代码进行了任何更改？
另一点 - 不要使用“幻数”，例如 75 和 105。由于价格在最后一个跨度中，因此可以使用以下代码：doc2

val el = doc2.select("#PriceSection span")
println(el?.last()?.text())

我的 Jsoup 解析代码再也找不到“价格”数据了

My Jsoup parsing code can no longer find the "price" data anymore
