如何在 Python 中用 selenium 刮这条线？

Question

Hey so im using selenium and im trying to scrape this line:

<em id="home-payOrderCommission" data-spm-anchor-id="portals._cps_home.overview.i0.6da22fe0oBPXYk">US $7.68</em>

Im trying to scrape the $7.68 part but I cant figure out how to do it, I tried by element ID but it doesn't seem to work

This is what I tried:

search = driver.find_element_by_id("portals._cps_home.overview.i0.2e1b2fe03tjTTD").text
print(search)

Answer 1

you are using the wrong id

use this instead :

id = 'home-payOrderCommission'

in code :

search = driver.find_element_by_id("home-payOrderCommission").text
print(search)

or a way better approach here is to use Explicit waits :

from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC
wait = WebDriverWait(driver, 10)
print(wait.until(EC.visibility_of_element_located((By.ID, "home-payOrderCommission"))).text)

PS :-

.text is a method available in Selenium-Python bindings, basically to get the text between the ID tag in your case, and in general to extract the text of an web element.

Answer 2

You are using a wrong locator.
As can be seen from the element you presented, it has id attribute with value of home-payOrderCommission and data-spm-anchor-id attribute with value of portals._cps_home.overview.i0.6da22fe0oBPXYk .
So, to use find_element_by_id method the value is home-payOrderCommission .
Try this:

search = driver.find_element_by_id("home-payOrderCommission").text
print(search)
