使用“更多”文本抓取評論

Question

正如標題所述，我需要幫助從這個名為 TripAdivsor 的網站上抓取評論。 我使用的具體鏈接是https://www.tripadvisor.co.uk/Restaurant_Review-g60834-d4106745-Reviews-McDonald_s-Page_Arizona.html

問題是在某些評論中，有“更多”文本可以查看評論的其余部分（例如，上面鏈接上的第二個評論）。 如何抓取包含此“更多”文本的評論？

有沒有辦法在我點擊鏈接時已經打開它們，或者這是找到包含整個評論的正確標簽的問題？

使用硒和美麗的湯。如果點擊更多按鈕並獲取 page_source，請檢查更多按鈕。

from selenium import webdriver
from bs4 import BeautifulSoup
import time
driver = webdriver.Chrome()
driver.get('https://www.tripadvisor.co.uk/Restaurant_Review-g60834-d4106745-Reviews-McDonald_s-Page_Arizona.html')
if len(driver.find_elements_by_xpath("//span[@class='taLnk ulBlueLinks'][contains(.,'More')]"))>0:
    driver.find_elements_by_xpath("//span[@class='taLnk ulBlueLinks'][contains(.,'More')]")[0].click()

time.sleep(3)
soup=BeautifulSoup(driver.page_source,'html.parser')
driver.quit()
items=[item.text for item in soup.select("p.partial_entry")]
print(items)
