如何通过 xpath 在 Selenium 中进行抓取？

Question

我想通过 xpath 单击页面上的按钮：https://igs.org/network/。我在下面写了这样的示例代码：

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import time

PATH = "C:\Program Files (x86)\chromedriver.exe"

driver = webdriver.Chrome(PATH)
url='https://igs.org/network/'
driver.get(url)
time.sleep(4)
myxpath = '/html/body/main/div/div/div[2]/div/div[2]/div[1]/div[2]/button[2]'
el = driver.find_element_by_xpath(myxpath).click()

我有这样的错误

NoSuchElementException: no such element: Unable to locate element: {"method":"xpath","selector":"/html/body/main/div/div/div2/div/div2/div1/div2/button2"}

我做错了什么？有人对导航这些元素有任何想法吗？

Answer 1

那个按钮的 xpath 就是这个 //*[@id="side-controls"]/button[2]

Answer 2

您尝试点击的元素在 iframe 中。您需要先切换到 iframe 才能访问该元素。

使用 WebDriverWait() 并等待框架可用并切换它并跟随 css 选择器。

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import time

PATH = "C:\Program Files (x86)\chromedriver.exe"

driver = webdriver.Chrome(PATH)
url='https://igs.org/network/'
driver.get(url
wait=WebDriverWait(driver, 20)
wait.until(EC.frame_to_be_available_and_switch_to_it((By.CSS_SELECTOR, "iframe[src='/imaps/map.html']")))
wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, 'button.toggler'))).click()
