Answer 1

要从指定区域提取文本，您需要为visibility_of_element_located()归纳WebDriverWait，您可以使用以下解决方案：

• 代码块：

  from selenium import webdriver
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.support import expected_conditions as EC
  
  options = webdriver.ChromeOptions() 
  options.add_argument("start-maximized")
  options.add_argument("--disable-extensions")
  options.add_argument('disable-infobars')
  driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
  driver.get('https://www.kobo.com/tw/zh/ebook/NXUCYsE9cD6OWhvtdTqQQQ')
  print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//h2[text()='電子書詳細資料']//following::ul[1]//li/a[@class='description-anchor']/span"))).text)
  driver.quit()

Answer 2

尝试以下代码。在

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

driver.get("https://www.kobo.com/tw/zh/ebook/NXUCYsE9cD6OWhvtdTqQQQ")
element=WebDriverWait(driver,30).until(EC.element_to_be_clickable((By.CSS_SELECTOR,'a.description-anchor span[translate="no"]')))
print(element.text)

Answer 3

你做错事了：

BookTitle[0].getWindowHandle()不应该在这里做任何事情

只需尝试：

driver.find_element_by_css_selector("a[class='description-anchor']>span").text
