How to delete blank values from a table useing find_element of Selenium Python

Question

I got the problem with blank elements. I used to find elements in website selenium and I recived list with of elements but some of them are blank (exactly half).

Website: https://www.cmegroup.com/markets/energy/refined-products/gasoil-01-rotterdam-barges-swap.quotes.html

I'm looking for value from column name "MONTH", rest of columns work correctly (I recived list without empty values).

main = driver.find_element(By.ID, "main-content")
time.sleep(10)
matches = main.find_elements(By.XPATH,
                          '//*[@id="productTabData"]/div/div/div/div/div/div[2]/div/div/div/div/div/div[5]/div/div/div/div[1]/div/table/tbody/tr')
time.sleep(10)
dane = []
for match in matches:
    Date = match.find_element(By.XPATH, "./td[1]/div/span/b").text
    Price = match.find_element(By.XPATH, "./td[5]").text
    Updated = match.find_element(By.XPATH, "./td[10]").text
    print(Date)
    table = {
        "DataPL" : Date,
        "GO" : Price,
        "Updated" : Updated
    }

    dane.append(table)
df=pd.DataFrame(dane)

To solve problem I used .shift method(pandas) but I'm looking better solve

df["DataPL"] = df["DataPL"].shift(-18)
df = df.iloc[0:17,:2]

maybe you can check if its empty and not append it at all? – Rolandas Ulevicius Feb 23 '23 at 09:50 — Rolandas Ulevicius, Feb 23 '23 at 09:50

To scrape table within the webpage you need to induce WebDriverWait for the visibility_of_element_located() for the <table> element and using DataFrame from Pandas you can use the following Locator Strategy:

Code block:

driver.get('https://www.cmegroup.com/markets/energy/refined-products/gasoil-01-rotterdam-barges-swap.quotes.html')
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "button#onetrust-accept-btn-handler"))).click()
data = WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.CSS_SELECTOR, "div#productTabData table"))).get_attribute("outerHTML")
df = pd.read_html(data)
print(df)
driver.quit()

Console Output:
