Python 从新闻网站中提取用户评论

这是我需要提取所有评论的链接

---

但是我的代码只提取了前10条注释。单击按钮后，将动态加载其他10条注释。如何使用PythonSelenium提取所有这些注释的想法是查找页面上有多少“更多想法”元素。每次单击按钮并加载更多评论时，就会出现一个“更多想法”红色按钮。实施：

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


def wait(dr, x):
  element = WebDriverWait(dr, 50).until(
    EC.presence_of_all_elements_located((By.XPATH, x))
)
return element
from selenium import webdriver
browser = webdriver.Firefox()
browser.get("http://www.dinamalar.com/user_comments.asp? uid=14701&name=%E0%AE%A4%E0%AE%AE%E0%AE%BF%E0%AE%B4%E0%AF%8D%E0%AE%9A%E0%AF%86%E0%AE%B2%E0%AF%8D%E0%AE%B5%E0%AE%A9%E0%AF%8D")
for elem in wait(browser, '//*[@id="commsec"]/div[2]/div[1]'):
print elem.text

请注意，我还删除了URL中的额外空间。

谢谢，效果很好。我是这方面的初学者，那么如何comments@VinayakumarR我会在这里使用XPath:

comments=[element.text for element in browser.find_elements\u by_XPath（“//div[@class='boxcmt1']//a[@class='heading']/following sibling:：div”）]

。请测试一下。谢谢。在将这一行添加到现有代码后，显示了警告I/O警告找到了非ASCII，但我尝试运行它，它显示了一个错误此操作很好注释=[element.text for element in browser.find_elements_by_xpath（“//div[@class='boxcmt1']//a[@class='heading']”），但它返回unicode@VinayakumarR当然可以，但是unicode有什么问题？谢谢
