為什么 Selenium 按類查找元素的新方法不能正常工作？

Question

我已將我的 selenium 版本更新為selenium 4 ，它現在有一種查找元素的新方法，因為driver.find_elements_by_class()現在被認為已棄用。我正在使用此代碼：

import time
import csv
import requests
import re
from selenium import webdriver
from selenium.webdriver.firefox.service import Service
from selenium.webdriver.common.by import By



def load():
    geoblock = webdriver.FirefoxOptions()
    geoblock.set_preference("geo.prompt.testing", True)
    geoblock.set_preference("geo.prompt.testing.allow", False)
    driver = webdriver.Firefox(service=Service(executable_path="/home/thecowmilk/PycharmProjects/webscraping"
                                                               "/testing/geckodriver"), options=geoblock)
    driver.get(f"file:///home/thecowmilk/PycharmProjects/webscraping/testing/coches.html")

    href = driver.find_elements(By.CLASS_NAME, 'mt-CardBasic-titleLink')
    print(href)
    driver.quit()


def main():
    load()


main()

它給了我這個輸出：

想知道我錯過了什么...

編輯：我知道find_elements()會返回一個列表，但我期待這樣的事情：

<a class="mt-CardBasic-titleLink" title="LEXUS IS 300h Hybrid Drive Navi Tecno 4p." href="https://www.coches.net/lexus-is-300h-hybrid-drive-navi-tecno-4p-electrico-hibrido-2014-en-madrid-51582664-covo.aspx" target="_self"></a>

所以我可以獲得href值。

Answer 1

如果您只尋找一個元素，只需使用find_element()代替。 獲取元素后，您可以通過get_attribute('href')獲取href 。

簡而言之，

elem = driver.find_element(By.CLASS_NAME, 'mt-CardBasic-titleLink')
href = elem.get_attribute('href')
