欢迎使用StackOverflow！请阅读常见问题解答的How to ask a question部分。

解释你是如何遇到你试图解决的问题，以及任何妨碍你自己解决问题的困难。

到目前为止，您试图解决这个问题是什么？

让我们开始吧。

您需要的只是find和find_all功能。

soup = BeautifulSoup(html_string)

status = soup.find('img').get('alt')  # get 'alt' content of the first <img> tag.

# find the first <td> tag with a class="test", get its content, split it using spaces,
version = soup.find('td', class_='test').text.split()[0]  # and get the first substring
time_start = soup.find('div', class_='start').text
time_end = soup.find('div', class_='end').text
user = soup.find_all('td')[2].text  # get a third <td>'s content.

print status  # QUEUED
print version  # v1402beta_150127_1_OTM_TICKETS_dv_c_UID142307274200
print time_start  # (04.02) 23:29
print time_end  # ~  >        () >
print user  # mcordeix

只需阅读bs4's documentation 10分钟并亲自尝试只需弹出Python解释器，分配html_string变量，导入beautifulsoup库，然后尝试。

我确定您可以自己解决time_end内容留下的问题。这并不难。

使用beautifulsoup在python中解析html
