我的代码正在从Facebook Marketplace抓取房屋数据，但遇到了一个问题。最初，当页面打开时，它只能读取24个房源。但是，当我尝试通过向下滚动页面加载更多房源时，我的代码开始从开头读取所有房源，而不是第25个房源。如何解决此问题？

open = driver.find_elements(By.XPATH, '//div[@ class="x3ct3a4"]')
#open it's a list of all clickable housing listings when I open the page

while True:
    for o in open:
        sleep(random.randint(1, 2))

        #Here I read the data that I need 

        close_button = driver.find_element(By.XPATH, close_xpath)
        close_button.click()
        sleep(random.randint(1, 2))
        #Here I close the listing and go to the next one
        
    #When I read all 24 listings that were in the 'open' list, I then scroll the page down and try to get new listings and then read them

    driver.execute_script('window.scrollTo(0, document.body.scrollHeight);')
    sleep(random.randint(2, 4)
    open = driver.find_elements(By.XPATH, open_xpath)

    #But after the scroll, my code starts reading the same listings that it already read.

以下是我的输出：

1
['', '2 Beds 1 Bath Apartment']
['$1,600 / Month']
2
['', '1 Bed 1 Bath Apartment']
['$1,500 / Month']

.

.
24
['', '2 Beds 2 Baths Apartment']
['$1,350 / Month']
25
['', '2 Beds 1 Bath Apartment']
['$1,600 / Month']
26
['', '1 Bed 1 Bath Apartment']
['$1,500 / Month']

因此，在第24次打开链接后，代码再次开始读取所有清单。
