Python 如何使用bs4浏览html？

今天下午刚开始学习python。尝试从kubuntu.org（简单html）的rss提要中获取信息，但我不知道如何浏览html，只打印提要标题：

#!/usr/bin/python3.5
import bs4 as bs
import urllib.request

site = urllib.request.urlopen('https://kubuntu.org/feed').read()
soup = bs.BeautifulSoup(site, 'lxml')

for title in soup.find_all('item'):
    print(title.text)

编辑：

将

title

添加到

find_all

行可以满足我的需求，但仍有大量数据使用title标记

#!/usr/bin/python3.5
import bs4 as bs
import urllib.request

site = urllib.request.urlopen('https://kubuntu.org/feed').read()
soup = bs.BeautifulSoup(site, 'lxml')

for title in soup.find_all(['item', 'title']):
    print(title.text)

---

只需访问

标题

标记为

项目

的子节点：

...
for item in soup.find_all('item'):
    print(item.title.text)

输出：
