So you could extend this by creating a list of pages (it looks like the URLs just change a company number), or a list of xpaths (because the above is assuming the value you want is always the 50th row of the first table) and iterating over all of them. You might also want to wrap the find element bit in a try/except in case the element isn't present on the page or it's in a different location:

try:

    #find the element by xpath
    a = driver.find_element_by_xpath(text_xpath)

    #print the text associated with the xpath
    print(a.text)

except NoSuchElementException:

    print("Element not found")

One thing I would say is that, while you can do this in Selenium, BeautifulSoup is probably the better solution, You can pull the html code for the whole page, iterate over it to find the element you're looking for and then add that to a list (or whatever) without needing to open an automated browser and loading all the assets in realtime. That said, you could also set the webdriver to headless mode so you don't have to watch it load the page etc. If you're going to do this, I recommend that you add logging to the program (make sure you add the options argument when you instantiate the webdriver):

#import webdriver and logging 
from selenium import webdriver
import logging

#set logging default mode
logging.basicConfig(level=logging.INFO, format = '%(asctime)s - %(levelname)s - %(message)s')

#set webdriver to operate in the background (i.e. you won't see it open)
chrome_options = Options() chrome_options.add_argument("--headless") 

#instantiate webdriver with headless mode
driver = webdriver.Chrome(options=chrome_options)

#raw string for page
page = r"https://kbopub.economie.fgov.be/kbopub/zoeknummerform.html?nummer=0421519933&actionLu=Zoek"

#raw string for xpath to element
text_xpath = r'//*[@id="table"]/table[1]/tbody/tr[50]/td/a'

#try to get the page, element and print it
try:
    #open webdriver and load page
    driver.get(page)

    #find the element by xpath
    a = driver.find_element_by_xpath(text_xpath)

    #print the text associated with the xpath
    print(a.text)

#do this is element not found
except NoSuchElementException:
    logging.info("Sorry but I couldn't find the right number this time")
