我正在嘗試從 booking.com 上抓取一些資訊。我處理了一些東西，比如分頁，提取標題等。
我試圖從這里提取客人的數量。
這是我的代碼：
driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()))
driver.maximize_window()
test_url = 'https://www.booking.com/hotel/gr/diamandi-20.en-gb.html?label=gen173nr-1DCAEoggI46AdIM1gEaFyIAQGYAQm4ARjIAQzYAQPoAQGIAgGoAgS4ApGp7ZgGwAIB0gIkZTBjOTA2MTQtYTc0MC00YWUwLTk5ZWEtMWNiYzg3NThiNGQ12AIE4AIB&sid=47583bd8c0122ee70cdd7bb0b06b0944&aid=304142&ucfs=1&arphpl=1&checkin=2022-10-24&checkout=2022-10-30&dest_id=-829252&dest_type=city&group_adults=2&req_adults=2&no_rooms=1&group_children=0&req_children=0&hpos=2&hapos=2&sr_order=popularity&srpvid=f0f16af3449102aa&srepoch=1662736362&all_sr_blocks=852390201_352617405_2_0_0&highlighted_blocks=852390201_352617405_2_0_0&matching_block_id=852390201_352617405_2_0_0&sr_pri_blocks=852390201_352617405_2_0_0__30000&from=searchresults#hotelTmpl'
driver.get(test_url)
time.sleep(3)
soup2 = BeautifulSoup(driver.page_source, 'lxml')
guests = soup2.select_one('span.xp__guests__count')
guests = guests.text if price else None
amenities = soup2.select_one('div.hprt-facilities-block')
結果是這個'\n2 adults\n·\n\n0 children\n\n·\n\n1 room\n\n'
我知道使用一些正則運算式我可以提取資訊，但我想要，但我想了解是否有辦法從上面的圖片中直接提取“2 個成年人”。
謝謝。

這是獲取該資訊的一種方法，無需使用 BeautifulSoup（為什么要決議頁面兩次？）：
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
[...]
wait = WebDriverWait(browser, 20)
url = 'https://www.booking.com/hotel/gr/diamandi-20.en-gb.html?label=gen173nr-1DCAEoggI46AdIM1gEaFyIAQGYAQm4ARjIAQzYAQPoAQGIAgGoAgS4ApGp7ZgGwAIB0gIkZTBjOTA2MTQtYTc0MC00YWUwLTk5ZWEtMWNiYzg3NThiNGQ12AIE4AIB&sid=47583bd8c0122ee70cdd7bb0b06b0944&aid=304142&ucfs=1&arphpl=1&checkin=2022-10-24&checkout=2022-10-30&dest_id=-829252&dest_type=city&group_adults=2&req_adults=2&no_rooms=1&group_children=0&req_children=0&hpos=2&hapos=2&sr_order=popularity&srpvid=f0f16af3449102aa&srepoch=1662736362&all_sr_blocks=852390201_352617405_2_0_0&highlighted_blocks=852390201_352617405_2_0_0&matching_block_id=852390201_352617405_2_0_0&sr_pri_blocks=852390201_352617405_2_0_0__30000&from=searchresults#hotelTmpl'
browser.get(url)
guest_count = wait.until(EC.element_to_be_clickable((By.CSS_SELECTOR, "span[class='xp__guests__count']"))).find_element(By.TAG_NAME, "span")
print(guest_count.text)
結果在終端：
2 adults

我沒用過BeautifulSoup。我使用硒。這就是我在 Selenium 中的做法：
import time
from selenium import webdriver
from selenium.webdriver.common.by import By
driver = webdriver.Chrome()
driver.maximize_window()
test_url = 'https://www.booking.com/hotel/gr/diamandi-20.en-gb.html?label=gen173nr-1DCAEoggI46AdIM1gEaFyIAQGYAQm4ARjIAQzYAQPoAQGIAgGoAgS4ApGp7ZgGwAIB0gIkZTBjOTA2MTQtYTc0MC00YWUwLTk5ZWEtMWNiYzg3NThiNGQ12AIE4AIB&sid=47583bd8c0122ee70cdd7bb0b06b0944&aid=304142&ucfs=1&arphpl=1&checkin=2022-10-24&checkout=2022-10-30&dest_id=-829252&dest_type=city&group_adults=2&req_adults=2&no_rooms=1&group_children=0&req_children=0&hpos=2&hapos=2&sr_order=popularity&srpvid=f0f16af3449102aa&srepoch=1662736362&all_sr_blocks=852390201_352617405_2_0_0&highlighted_blocks=852390201_352617405_2_0_0&matching_block_id=852390201_352617405_2_0_0&sr_pri_blocks=852390201_352617405_2_0_0__30000&from=searchresults#hotelTmpl'
driver.get(test_url)
time.sleep(3)
element = driver.find_element(By.XPATH,"//span[@class='xp__guests__count']")
adults = int(element.text.split(" adults")[0])
print(str(adults))
基本上，我找到了包含您要查找的文本的 span 元素。.text為您提供所有內部文本（在本例中為“2 個成人·0 個兒童·1 個房間”）。
下一行只取“成年人”之前的字串部分，然后將其轉換為 int。
