I'd like to get the elements by Selenium as the attached pic:

ess-cell 

However, the following code didn't work even though:

find_element_by_tag_name('div')

part works correctly. Does anyone know why?

row.find_element_by_tag_name('div').find_element_by_tag_name('div').find_elements_by_tag_name('ess-cell')

CodePudding user response：

To get the elements <ess-cell ...> you can use either of the following Locator Strategies:

• Using css_selector:

  elements = row.find_elements(By.CSS_SELECTOR, "div > div ess-cell.data-numeric")
  

• Using xpath:

  elements = row.find_elements(By.XPATH, "./div/div//ess-cell[contains(@class, 'data-numeric')]")
  

Ideally you have to induce WebDriverWait for presence_of_all_elements_located() and you can use either of the following locator strategies:

• Using CSS_SELECTOR:

  elements = WebDriverWait(row, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "div > div ess-cell.data-numeric")))
  

• Using XPATH:

  elements = WebDriverWait(row, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "./div/div//ess-cell[contains(@class, 'data-numeric')]")))
  

• Note : You have to add the following imports :

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