为什么在使用此 xpath 语法时收到已弃用的警告?
Why am I getting a deprecated warning when using this xpath syntax?
问:
我正在使用硒打印网页上的所有产品链接。这是我的代码:
from selenium.webdriver import Chrome
driver_path = PATH = r"C:\Users\David\Desktop\Selenium\chromedriver.exe"
driver = Chrome(executable_path=driver_path)
driver.get('https://www.lazada.com.ph/shop-portable-speakers/?spm=a2o4l.home.cate_2_2.2.239e359dxynAFV'
)
xpath = '//*[@id="root"]/div/div[2]/div[1]/div/div[1]/div[2]'
link_elements = driver.find_elements_by_xpath(xpath)
links = []
for link_el in link_elements:
href = link_el.get_attribute("href")
print (href)
links.append(href)
driver.quit()
该代码运行并打印以下内容:
runfile('C:/Users/David/Desktop/Selenium/untitled1.py', wdir='C:/Users/David/Desktop/Selenium')
C:\Users\David\Desktop\Selenium\untitled1.py:4: DeprecationWarning: executable_path has been deprecated, please pass in a Service object
driver = Chrome(executable_path=driver_path)
C:\Users\David\Desktop\Selenium\untitled1.py:10: DeprecationWarning: find_elements_by_* commands are deprecated. Please use find_elements() instead
link_elements = driver.find_elements_by_xpath(xpath)
None
关于我在这里做错了什么的任何想法?

弃用 selenium4 作为键 h 时,您必须使用该类的实例以及命令,如下所述。executable_pat
Service()
ChromeDriverManager().install()
先决条件 确保:
Selenium 升级到 v4.0.0
pip3 install -U selenium
已安装 Webdriver Manager for Python
pip3 install webdriver-manager
Selenium v4 兼容代码块
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from webdriver_manager.chrome import ChromeDriverManager
driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()))
driver.get("https://www.google.com")
也使用
driver.find_elements(By.XPATH, "xpath")
而不是
driver.find_elements_by_xpath(xpath)

看来我已经安装了这些。我认为这与错误有关:DeprecationWarning:find_elements_by_xpath已弃用。请使用 find_elements(by=By.XPATH, value=xpath) 代替 link_elements = driver.find_elements_by_xpath(xpath)。我尝试使用这种语法,但它告诉我变量是未定义的。不确定我是否在这里犯了错误。
