正如标题所述，我需要帮助从这个称为TripAdivsor的网站上刮取评论。我正在使用的特定链接是https://www.tripadvisor.co.uk/Restaurant_Review-g60834-d4106745-Reviews-McDonald_s-Page_Arizona.html
问题在于某些评论上有“更多”文本来查看其余评论（例如，上面链接中的第二条评论）。如何刮擦包含“更多”文字的评论？
当我单击链接时，是否已经可以打开它们？或者这是找到包含整个评论的正确标签的问题吗？

使用硒和美丽的汤。单击“更多”按钮，然后获取page_source。
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)
输出：
