HTML 元素未使用 python's.text 打印

Question

from selenium import webdriver
import selenium.webdriver.common.keys


def main():



    PATH = r"D:\msedgedriver"
    driver = webdriver.Edge(PATH)
    driver.get("https://reservation.frontdesksuite.ca/rcfs/richcraftkanata/Home/Index?Culture=en&PageId=b3b9b36f-8401-466d-b4c4-19eb5547b43a&ButtonId=00000000-0000-0000-0000-000000000000")
    #get the website
    list_of_elements = driver.find_elements_by_xpath('//a[@href]')
    #get all of the items in the content class
    print(len(list_of_elements))
    #print length - for testing
    driver.quit()
    for link in list_of_elements:
        #iterate through the list
        print("iterated!")
        print(link.text)
        print("printed!")



main()

我的目標是打印此網頁“a”標簽中每個元素的實際鏈接，並嘗試通過打印每個 python href 元素的 .text 形式來實現。 但是無論出於何種原因，它都不起作用。

這是我收到的錯誤：

您沒有顯示完整的錯誤消息，也沒有顯示最少的工作代碼——所以我猜。

Selenium 處理對瀏覽器 memory 中對象的引用 - 所以如果您仍想從瀏覽器中獲取某些內容，請不要關閉它。

你必須在for循環之后使用driver.close()

最小的工作代碼

from selenium import webdriver

def main():

    driver = webdriver.Firefox()
    driver.get('https://books.toscrape.com')

    list_of_elements = driver.find_elements_by_xpath('//a[@href]')

    print('len:', len(list_of_elements))

    for link in list_of_elements:
        print("iterated!")
        print(link.text)
        print("printed!")
        
    driver.quit()   # <--- after `for`-loop

# --- main ---

main()
