Python/Selenium - “没有这样的元素:无法定位元素" [英] Python/Selenium - "no such element: Unable to locate element"

问题描述

我很难找到

另一个更新:

driver.get(https://www.weforum.org/reports/global-gender-gap-report-2021/in-full/economy-profiles#economy-profiles")等待=WebDriverWait(驱动程序，10)等到(EC.frame_to_be_available_and_switch_to_it((按.ID，iFrameResizer0")))driver.find_element_by_xpath("///*[name()='svg' and @class='sc-gxMtzJ bRxjeC']").click()

I'm having a really hard time locating elements on this website. My ultimate aim here is scrape the score card data for each country. The way I've envisioned doing that is to have selenium click list view (as opposed to the default country view) and loop going in and out of all the country profiles, scraping the data for each country along the way. But methods to locate elements on the page that worked for me in the past, have been fruitless with this site.

Here's some sample code outlining my issue.

from selenium import webdriver

driver = webdriver.Chrome(executable_path= "C:/work/chromedriver.exe")
driver.get('https://www.weforum.org/reports/global-gender-gap-report-2021/in-full/economy-profiles#economy-profiles')

# click the `list` view option
driver.find_element_by_xpath('//*[@id="root"]/div/div[1]/div[2]/div[2]/svg[2]')

As you can see, I've only gotten as far as step 1 of my plan. I've tried what other questions have suggested as far as adding waits, but to no avail. I see the site fully loaded in my DOM, but no xpaths are working for any element on there I can find. I apologize if this question is posted too often, but do know that any and all help is immensely appreciated. Thank you!

解决方案

The element is inside an iframe you need to switch it to access the element.

Use WebDriverWait() wait for frame_to_be_available_and_switch_to_it()

driver.get("https://www.weforum.org/reports/global-gender-gap-report-2021/in-full/economy-profiles#economy-profiles")
wait=WebDriverWait(driver,10)
wait.until(EC.frame_to_be_available_and_switch_to_it((By.ID, "iFrameResizer0")))
wait.until(EC.element_to_be_clickable((By.XPATH,"//*[name()='svg' and @class='sc-gxMtzJ bRxjeC']"))).click()

You need following imports.

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

Another update:

driver.get("https://www.weforum.org/reports/global-gender-gap-report-2021/in-full/economy-profiles#economy-profiles")
wait=WebDriverWait(driver,10)
wait.until(EC.frame_to_be_available_and_switch_to_it((By.ID, "iFrameResizer0")))
driver.find_element_by_xpath("//*[name()='svg' and @class='sc-gxMtzJ bRxjeC']").click()
