Python，Selenium - 解析。无法从动态填充中获取信息

Question

我想学习如何从动态生成的字段中获取信息。 当我尝试简单的网站时，一切正常。然后我决定尝试更困难，现在我无法弄清楚。我花了大约两周的时间，一遍又一遍地划掉我在 Internet 上找到的解决方案选项。 现在我不确定我是否可以通过这种方式获得出现在网站上的信息。当然，很可能我做错了什么，但我无法接受一些新的想法。现在，我决定在这里问。或许有人明白这一点，可以提示。如果是 - 请给我一些例子。

我用来学习的网站 - kbp.aero/en

我想要获取的信息（到达时间表） - .tbody .tr .td

例如我试过：

1.

URL = 'https://kbp.aero/en/'
    HEADERS = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/95.0.4638.69 Safari/537.36'
    }
    time.sleep(1)
    response = requests.get(URL, headers = HEADERS)
    soup = BeautifulSoup(response.content, 'html.parser')
    items = soup.find('div', class_ = 'table_wrp out yesterday')
    items = items.findAll('tr', class_ = 'tr')
    comps = []
    if(len(items) > 0):
        for item in items:
            comps.append({
                'title':item.find('td', class_ = 'td').get_text(strip = True),
            })
    for comp in comps:
        print(comp['title'])
    # for item in items:
    #     comps.append({
    #         'text': item.get_text(strip=True)
    #     })
    #
    # for comp in comps:
    #     print(comp['text'])

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


def main():
    driver = webdriver.Chrome()
    driver.get("https://kbp.aero/en/")

    wait = WebDriverWait(driver, 10)
    element = wait.until(EC.text_to_be_present_in_element((By.CLASS_NAME, 'tbody'), ''))

    tds = element.find_elements(By.CLASS_NAME, "td")
    for td in tds:
        print(td.text)

    # try:
    #     element = WebDriverWait(driver, 10).until(
    #         EC.presence_of_element_located((By.CLASS_NAME, "tbody"))
    #     )
    #     tds = element.find_elements(By.CLASS_NAME, "td")
    #     for td in tds:
    #         print(td.text)
    #
    # finally:
    #     driver.quit()

感谢您的建议。

Answer 1

这将获取整个表格数据：

   from time import sleep
   from selenium import webdriver
   from selenium.webdriver.common.by import By

   PATH = r"chromedriverexe path"
   driver = webdriver.Chrome(PATH)

   driver.get("https://kbp.aero/en/")
   driver.maximize_window()
   sleep(3)
   print(driver.find_element(By.CSS_SELECTOR, "div.table_wrp.out.today > table").text)

输出：
