How to get the value of an element in Python + Selenium?

问题

I have got this HTML element in my Python (3.6.3) code (as Selenium webelement of course):

<span class="ocenaCzastkowa masterTooltip" style="color:#000000;" alt="Kod: 
pd1<br/>Opis: praca domowa<br/>Waga: 2,00<br/>Data: 12.09.2017<br/>Nauczyciel: 
(NAME CENSORED)">5</span>

and I want to get the value at the end (which is 5 in this case) and I have got no idea how to get it. obviously I can't use webelement.get_attribute() cause I don't know the name of the attribute.

回答1:

Try the following code:

span_element = driver.find_element_by_css_selector(".ocenaCzastkowa.masterTooltip")
span_element.text # This will return "5".

PS: Also you can use span_element.get_attribute("value").

Hope it helps you!

To print the textContent i.e. 5 you can use either of the following Locator Strategies:

• Using css_selector:

  print(driver.find_element(By.CSS_SELECTOR, "div.ocenaCzastkowa.masterTooltip").text)
  

• Using xpath:

  print(driver.find_element(By.XPATH, "//span[@class='ocenaCzastkowa masterTooltip']").text)

Ideally you need to induce WebDriverWait for the visibility_of_element_located() and you can use either of the following Locator Strategies:

• Using CSS_SELECTOR:

  print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "div.ocenaCzastkowa.masterTooltip"))).text)
  

• Using XPATH:

  print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//span[@class='ocenaCzastkowa masterTooltip']"))).text)
  

• 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
