解决我的问题

Answer 1

1. 你怎么得到usb错误和蓝牙?发生什么事了?

2. type hefrom selenium import webdriver从哪里复制粘贴?

3. 变量all_matches_button从未在您的代码中使用过，并且当单击元素时不需要保存任何内容到变量

   #Locating and clicking an element
   all_matches_button=driver.find_element(by='xpath',value="//label[normalize-space()='All matches']").click()
   

4. 这里是开始深入挖掘的工作代码

   from time import sleep
   from selenium import webdriver
   from selenium.webdriver.common.by import By
   from selenium.webdriver.chrome.options import Options
   chrome_options = Options()
   chrome_options.add_experimental_option("detach", True)
   website = 'https://www.adamchoi.co.uk/overs/detailed'
   driver = webdriver.Chrome(options=chrome_options)
   driver.get(website)
   sleep(4)
   tr_elements = driver.find_elements(By.XPATH, "//tr")
   for tr in tr_elements:
   print(tr.tag_name, tr.get_attribute('textContent'))
   

Answer 2

但是，此消息不应阻止您获得抓取结果。尝试在最后一行添加斜杠

来更正xpath。

matches=driver.find_elements(by="xpath",value='//tr')
