Selenium Python 从网站中提取信息并将其转储为 JSON 格式

Question

I'm trying to open a Hotel website www.booking.com and extract the name, price, location, and link from the top 50 search results which are sorted by cheapest first. I'm using Selenium python to automate the process However some HTML elements are targetable while others are not. after inspecting the website I realized that all hotel names have the class name: fcab3ed991 a23c043802

I tried to target all of them and put them into an array as seen in my code below. But I can't seem to target the element correctly. What I'm I doing wrong?

Answer 1

To extract the texts from the name and price fields you can use list comprehension and you can use the following locator strategies :

• Code block:

   driver.execute("get", {'url': 'https://www.booking.com/searchresults.html?label=gen173nr-1FCAEoggI46AdIM1gEaAKIAQGYATG4ARfIAQzYAQHoAQH4AQKIAgGoAgO4AvqR75YGwAIB0gIkZDQ4MTdjZDctYzIyNC00N2RlLWJhYjItZDU1YTAwMGU2M2Q12AIF4AIB&sid=8005d0cc6b75af8d0d2e74451b73cb8b&aid=304142&sb=1&sb_lp=1&src_elem=sb&error_url=https%3A%2F%2Fwww.booking.com%2Findex.html%3Flabel%3Dgen173nr-1FCAEoggI46AdIM1gEaAKIAQGYATG4ARfIAQzYAQHoAQH4AQKIAgGoAgO4AvqR75YGwAIB0gIkZDQ4MTdjZDctYzIyNC00N2RlLWJhYjItZDU1YTAwMGU2M2Q12AIF4AIB%26sid%3D8005d0cc6b75af8d0d2e74451b73cb8b%26sb_price_type%3Dtotal%26%26&ss=Jumeirah%2C+Dubai%2C+Dubai+Emirate%2C+United+Arab+Emirates&is_ski_area=&checkin_year=2022&checkin_month=8&checkin_monthday=1&checkout_year=2022&checkout_month=8&checkout_monthday=3&group_adults=2&group_children=0&no_rooms=1&map=1&b_h4u_keep_filters=&from_sf=1&ss_raw=jum&ac_position=1&ac_langcode=en&ac_click_type=b&dest_id=941&dest_type=district&place_id_lat=25.205553&place_id_lon=55.239216&search_pageview_id=c0ac477da63f02c2&search_pageview_id=c0ac477da63f02c2&search_selected=true&ac_suggestion_list_length=5&ac_suggestion_theme_list_length=0&order=price#map_closed'}) names = [my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "div[data-testid='title']")))] prices = [my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "div[data-testid='price-and-discounted-price'] > span")))] for i,j in zip(names, prices): print(f"{i} hotel price is {j}")

• Note : You have to add the following imports :

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

• Console Output:
