Synonymsテーブルからコンテンツを抽出するには、 visibility_of_all_elements_located()に対してWebDriverWaitを誘導する必要があり、次のLocator Strategyを使用できます。

  • XPATH の使用:

    driver.get("https://pubchem.ncbi.nlm.nih.gov/compound/71308229")
print([my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//th[text()='Synonyms']//following::td[1]//p")))])

  • コンソール出力:

    ['Lanthanum boride', '12008-21-8', 'Lanthanum hexaboride', 'MFCD00151350', 'B6La']

  • 注：次のインポートを追加する必要があります：

    from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

要素のテキストを明示的に取得する必要があります

synonyms= []
driver= webdriver.Chrome()
url = "https://pubchem.ncbi.nlm.nih.gov/compound/71308229"
driver.get(url)
synonym = driver.find_elements_by_class_name("overflow-x-auto")
synonyms.append([s.text for s in synonym])
print(synonyms)
driver.close()
