从Booking.com中抓取信息
从Booking.com中抓取信息
提问于 2022-09-11 20:46:21
我正在尝试从booking.com中获取一些信息。我处理了一些事情，如分页，摘录，标题等。
我在试着从这里提取客人的数量。
这是我的密码：
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') 结果是这个'\n2 adults\n·\n\n0 children\n\n·\n\n1 room\n\n'
我知道，通过一些regexp，我可以提取信息，但我想知道，但我想了解是否有办法直接从上面的图片中提取“2个成年人”。
谢谢。

这是一种无需使用BeautifulSoup (为什么要解析页面两次)的获取信息的方法：
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)终点站的结果：

我还没用过BeautifulSoup。我用硒。我在Selenium中就是这样做的：
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，我找到包含您要查找的文本的span元素。.text为您提供了所有的内部文本(在本例中，“2个成人·0名儿童·1个房间”)。
下一行只接受字符串中“成年人”之前的部分，然后将其转换为int。
