I just start learning python. So on this chapter it's basically to a create a price tracker using selenium.

The photo below is what I'm trying to get using selenium.

Screenshot

if i try

search_box = driver.find_element(By.CLASS_NAME, "a-price a-text-price a-size-medium apexPriceToPay")

it shows red sea of lines , saying no buch Message: no such element

Then I try

search_box = driver.find_element(By.CLASS_NAME, "a-offscreen")

the output is: <selenium.webdriver.remote.webelement.WebElement (session="0e1349ab77fff9cc0f9c565cc173927d", element="bbd837af-3cdf-4bd1-825c-9fd8cd27f719")>

I'm really new to programming...so I tried using .text at the end, no luck!

what can i do to get the price?

I would try this:

search_box = driver.find_element(By.CLASS_NAME, "apexPriceToPay")

Or maybe

search_box = driver.find_element(By.CSS_SELECTOR, ".a-price.a-text-price")

To give a precise answer we need to see the entire page HTML to find the shortest unique locator

CodePudding user response：

You need to take care of a couple of things:

1. You can't pass multiple classnames within driver.find_element(By.CLASS_NAME, "classA classB classC classD") as it may raise invalid selector.

2. Passing the classname a-offscreen selects 18 elements, so you even can't use it.

3. You will see the output as:

   <selenium.webdriver.remote.webelement.WebElement (session="0e1349ab77fff9cc0f9c565cc173927d", element="bbd837af-3cdf-4bd1-825c-9fd8cd27f719")>
   

   when you will print the element itself, which you don't need either.

Solution

To print the text $20.97 you can use the following Locator Strategy:

• Using xpath and text attribute:

  print(driver.find_element(By.XPATH, "//td[starts-with(., 'Price')]//following-sibling::td[1]/span[contains(@class, 'a-price')]/span[@aria-hidden='true']").text)
  

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

• Using xpath, the second <span> and get_attribute("innerHTML"):

  print(WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.XPATH, "//td[starts-with(., 'Price')]//following-sibling::td[1]/span[contains(@class, 'a-price')]/span[@aria-hidden='true']"))).get_attribute("innerHTML"))
  

• Console Output:

  $20.97
  

• 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
