I am trying to extract the text content from a ::before pseudo-element in an HTML document. I understand that traditional HTML parsers like BeautifulSoup cannot render CSS and thus cannot access pseudo-elements directly. Therefore, I am using Selenium to achieve this.

enter image description here
I want to get the text content of the ::before pseudo-element associated with the span element that has the class hs_kw11_configMs.

from selenium import webdriver

driver = webdriver.Chrome()

driver.get('example.com')


# The class is different every time. The general pattern is "hs_kw/d/d_config/w/w"
element = driver.find_element_by_css_selector('.hs_kw11_configMs')

before_content = driver.execute_script(
    "return window.getComputedStyle(arguments[0], '::before').getPropertyValue('content');",
    element
)

print(before_content.strip('"'))

driver.quit()

#Output: "content"
#Actual output: 

enter image description here

While this script runs without errors, I am not getting the expected text content from the ::before pseudo-element. Can anyone help me identify what I might be doing wrong or suggest a better approach to achieve this?
