当 xpath 存在时，无法在 selenium 中找到元素

Question

I am trying to scrape the text of this linked in post: https://www.linkedin.com/feed/update/urn:li:activity:6761903191849230336/?updateEntityUrn=urn%3Ali%3Afs_feedUpdate%3A%28V2%2Curn%3Ali%3Aactivity%3A6761903191849230336%29

my_url = 'https://www.linkedin.com/feed/update/urn:li:activity:6761903191849230336/?updateEntityUrn=urn%3Ali%3Afs_feedUpdate%3A%28V2%2Curn%3Ali%3Aactivity%3A6761903191849230336%29'
driver = webdriver.Chrome(r'C:\Users\Main\Documents\M&Saatchi\chromedriver')
driver.get(my_url)

sleep(5)
####MAIN PROGRAM#### - Page 1
source = soup(driver.page_source)

test = driver.find_element_by_xpath('//span[@class="break-words"]')

Currently I get:

NoSuchElementException: no such element: Unable to locate element: {"method":"xpath","selector":"//span[@class="break-words"]"}
  (Session info: chrome=88.0.4324.182)

I know this XPath exists using inspect element (see below)

Answer 1

Couldn't find the xpath for span class="break-words" inside Selenium but try this one.

wait = WebDriverWait(driver, 30)
driver.get('https://www.linkedin.com/feed/update/urn:li:activity:6761903191849230336/?updateEntityUrn=urn%3Ali%3Afs_feedUpdate%3A%28V2%2Curn%3Ali%3Aactivity%3A6761903191849230336%29')
elem=wait.until(EC.presence_of_element_located((By.CSS_SELECTOR,"p.share-update-card__update-text")))
print(elem.text)

Import

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