如何在手风琴Python中抓取隐藏文本

Question

我写了一个简单的脚本，返回澳大利亚赌博网站的具体信息。

它运作良好，但是我在打开每个手风琴下降时遇到了很多麻烦。我的脚本如下。

from selenium import webdriver
import time

chrome_path =r"C:\Users\Tom\Desktop\chromedriver.exe"
driver = webdriver.Chrome(chrome_path)
driver.get("https://pointsbet.com.au/basketball/NBA")

time.sleep(2)

driver.find_element_by_xpath("""/html/body/div[1]/div[2]/sport-competition-component/div[1]/div[2]/div[1]/div/event-list/div[1]/event/div/header/div[1]/h2/a""").click()
time.sleep(2)


posts = driver.find_elements_by_class_name("market")
for post in posts:
    print(post.text)
    with open('output.xls',mode ='a') as f:
        f.write(post.text)
        f.write('\n')

driver.quit()

该脚本打印类名“market”中包含的所有可见文本。

输出如下：

HEAD TO HEAD
Brooklyn Nets
1.29
Atlanta Hawks
3.78
LINE
Brooklyn Nets -8.0
1.95
Atlanta Hawks +8.0
1.89
TOTAL POINTS
Over 227.0
1.91
Under 227.0
1.91

我的问题是手风琴下有隐藏的文字。看截图：screenshot

- 例如，我无法抓取“双重结果”标题下的数据

一旦'点击'，脚本就可以了。

我写了一些自动点击手风琴的脚本，但不幸的是xpath名称随着每场比赛而改变。

有没有人知道如何自动点击所有手风琴（不知道元素信息），或者是否有人有替代解决方案。

欢迎任何帮助，谢谢

        f.write('\n')

d.quit()

您可以使用css类选择器来获取下拉列表集合，并通过迭代集合来单击它们。示例页面：

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.common.by import By

d = webdriver.Chrome()
d.get("https://pointsbet.com.au/basketball/NBA/58738")
expandable = WebDriverWait(d, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, ".h2.accordion-toggle.event-name")))
expandables = d.find_elements_by_css_selector('.h2.accordion-toggle.event-name')
for item in expandables:
    item.click()
