python - 如何在手风琴Python中抓取隐藏的文本

问题描述

我编写了一个简单的脚本，它从澳大利亚赌博网站返回特定信息。

它工作得很好，但是我在自动打开每个手风琴下拉菜单时遇到了很多麻烦。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： 截图

- 例如，我无法在“双重结果”标题下抓取数据

一旦它被“点击”，脚本就可以正常工作。

我已经编写了一些脚本来自动点击手风琴，但不幸的是 xpath 名称随着每次匹配而改变。

有谁知道如何自动一次单击所有手风琴（不知道元素信息），或者有没有人有替代解决方案。

欢迎任何帮助，谢谢

更新：

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
import time


chrome_path =r"C:\Users\Tom\Desktop\chromedriver.exe"

d = webdriver.Chrome(chrome_path)
d.get("https://pointsbet.com.au/basketball/NCAA-March-Madness")

time.sleep(2)

d.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)

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()


posts = d.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')

d.quit()

错误：

解决方案

您可以使用 css 类选择器来获取下拉列表的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()
