Selenium不会返回所需的所有元素

Question

我试图从这个website中获取一组房屋链接，但它只返回大约9个元素，尽管它有更多的元素。我也尝试过使用漂亮的汤，但同样的事情发生了，它并没有返回所有元素

含硒：

for i in range(10):
    time.sleep(1)
    scr1 = driver.find_element_by_xpath('//*[@id="search-page-list-container"]')
    driver.execute_script("arguments[0].scrollTop = arguments[0].scrollHeight", scr1)

link_tags = driver.find_elements_by_css_selector(".list-card-info a")
links = [link.get_attribute("href") for link in link_tags]
pprint(links)

对于bs4：

headers = {
           'accept-language': 'en-GB,en;q=0.8,en-US;q=0.6,ml;q=0.4',
           'user-agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko)'
                         'Chrome/74.0.3729.131 Safari/537.36'
           }
response = requests.get(ZILLOW_URL, headers=headers)
website_content = response.text

soup = BeautifulSoup(website_content, "html.parser")

link_tags = soup.select(".list-card-info a")
link_list = [link.get("href") for link in link_tags]
pprint(link_list)

输出：

'https://www.zillow.com/b/407-fairmount-ave-oakland-ca-9NTzMK/',
 'https://www.zillow.com/homedetails/1940-Buchanan-St-A-San-Francisco-CA-94115/15075413_zpid/',

有没有办法解决这个问题？我真的很感激你的帮助

您必须在循环中逐个滚动到每个元素，然后必须查找具有href的后代锚标记

driver.maximize_window()
#driver.implicitly_wait(30)
wait = WebDriverWait(driver, 50)
driver.get("https://www.zillow.com/homes/for_rent/1-_beds/?searchQueryState=%7B%22pagination%22%3A%7B%7D%2C%22mapBounds%22%3A%7B%22west%22%3A-123.7956336875%2C%22east%22%3A-121.6368202109375%2C%22south%22%3A37.02044483468766%2C%22north%22%3A38.36482775108166%7D%2C%22isMapVisible%22%3Atrue%2C%22filterState%22%3A%7B%22price%22%3A%7B%22max%22%3A872627%7D%2C%22beds%22%3A%7B%22min%22%3A1%7D%2C%22fore%22%3A%7B%22value%22%3Afalse%7D%2C%22mp%22%3A%7B%22max%22%3A3000%7D%2C%22auc%22%3A%7B%22value%22%3Afalse%7D%2C%22nc%22%3A%7B%22value%22%3Afalse%7D%2C%22fr%22%3A%7B%22value%22%3Atrue%7D%2C%22fsbo%22%3A%7B%22value%22%3Afalse%7D%2C%22cmsn%22%3A%7B%22value%22%3Afalse%7D%2C%22fsba%22%3A%7B%22value%22%3Afalse%7D%7D%2C%22isListVisible%22%3Atrue%2C%22mapZoom%22%3A9%7D")


j = 1
for i in range(len(driver.find_elements(By.XPATH, "//article"))):
    all_items = driver.find_element_by_xpath(f"(//article)[{j}]")
    driver.execute_script("arguments[0].scrollIntoView(true);", all_items)
    print(all_items.find_element_by_xpath('.//descendant::a').get_attribute('href'))
    j = j + 1
    time.sleep(2)

Answer 2

问题是网站。它添加了动态链接，因此您可以尝试滚动到页面底部，然后搜索链接

bottomFooter = driver.find_element_by_id("region-info-footer")
driver.execute_script("arguments[0].scrollIntoView();", bottomFooter)
