AttributeError:'str'对象没有属性'descendants'

问题描述

我正在尝试抓取网站的特定内容.我希望能到达:

I'm trying to scrape a particular piece of a website. I'm hoping to get to:

 <div class="inhoudsindicatie"><p><span class="hl0 highlightColor0">HR</span>: art. 81RO.</p></div>

，尤其是其中的第81RO条".

and in particular the "art. 81RO" part of it.

 from selenium import webdriver
 from bs4 import BeautifulSoup as soup
 driver.get('http://uitspraken.rechtspraak.nl/inziendocument?id=ECLI:NL:HR:2014:3004&showbutton=true&keyword=HR%3a')
 page=soup(driver.page_source, "html.parser")
 details=soup.findAll("span",{"class":"hl0 highlightColor0"})

它返回:

 AttributeError: 'str' object has no attribute 'descendants'

这对我的代码意味着什么?我阅读了有关后代的一般信息，并且我很确定自己听不懂.

What does this imply about my code ? I read the general information on descendants and I am quite sure I don't understand.

(我的主要兴趣是理解问题，解决问题是次要的，尽管当然受到高度赞赏)

(My main interest is in understanding the problem, solving it is secondary, though of course highly appreciated)

推荐答案

这对我有用:

import time
from selenium import webdriver
from bs4 import BeautifulSoup as soup
driver = webdriver.Chrome("/path/to/chromedriver")
driver.get('http://uitspraken.rechtspraak.nl/inziendocument?id=ECLI:NL:HR:2014:3004&showbutton=true&keyword=HR%3a')
time.sleep(5)
page = soup(driver.page_source, "html.parser")
details = page.select_one("span.hl0.highlightColor0").find_parent().get_text()
print(details)
driver.quit()

# output: HR: art. 81RO.

但是既然您还是在使用硒，为什么不坚持使用硒呢?

But since you're using selenium anyway, why not just stick with it?

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

driver = webdriver.Chrome("/path/to/chromedriver")
driver.get('http://uitspraken.rechtspraak.nl/inziendocument?id=ECLI:NL:HR:2014:3004&showbutton=true&keyword=HR%3a')
wait = WebDriverWait(driver, 10)
xpath = "//p/span[contains(@class, 'highlightColor0') and contains(@class, 'hl0')]/.."
details = wait.until(EC.visibility_of_element_located((By.XPATH, xpath)))
print(details.text)
driver.quit()

# output: HR: art. 81RO.

如果您不想使用"HR:"部分，可以将其删除:

If you don't want the 'HR:' part you can remove it:

details.split('HR: ')[1]

# output: art. 81RO.
