Python 使用beautifulsoup获取跨度标题

我有这个跨度，我想用beautifulsoup把它缩短7分钟

<span>In current traffic: 7 mins</span>

但不起作用

我的账号在下面

from bs4 import BeautifulSoup
import urllib2


url = "https://maps.google.com.au/maps?saddr=A6&daddr=A6&hl=en&ll=-33.877613,151.039867&spn=0.081236,0.083599&sll=-33.869204,151.034546&sspn=0.081244,0.083599&geocode=FYSu-v0d2KMACQ%3BFbp0-_0dJKoACQ&mra=ls&t=m&z=14&layer=t"

content = urllib2.urlopen(url).read()
soup = BeautifulSoup(content)

res = soup.find('span')
title = res['In current traffic']
print 'Current Listeners:', res.text

---

res

是带有文本的

标记。不能让BeautifulSoup进一步分解该文本，整个文本是一个单元：

使用字符串方法获取所需的零件：

>>> res.text.rsplit(':', 1)[-1].strip()
'7 mins'

---

res[…]

语法将允许您访问标记上的HTML属性，但是

根本没有属性。

您已经收到了它：

>>> res = soup.find('span')
>>> res
<span>In current traffic: 7 mins</span>
>>> 

要查找所需零件，可以使用“查找”：

pos = res.text.find(': ')
res.text[pos+2:]

因此，您的完整代码应该是：

from bs4 import BeautifulSoup
import urllib2


url = "https://maps.google.com.au/maps?saddr=A6&daddr=A6&hl=en&ll=-33.877613,151.039867&spn=0.081236,0.083599&sll=-33.869204,151.034546&sspn=0.081244,0.083599&geocode=FYSu-v0d2KMACQ%3BFbp0-_0dJKoACQ&mra=ls&t=m&z=14&layer=t"

content = urllib2.urlopen(url).read()
soup = BeautifulSoup(content)

div = soup.find('div', {'class':'altroute-rcol altroute-aux'}) #get the div where it's located
span = div.find('span')
pos = span.text.find(': ')
print 'Current Listeners:', span.text[pos+2:]

结果:

Current Listeners: 7 min

编辑：更新我的代码以使用您的链接。

希望这有帮助

抱歉，Martijn的答案完全回答了问题。抱歉，但它不起作用，请在我的编辑上方查找。我是从一个有很多跨度的网站上得到这个消息的，很抱歉edit7min是一个动态值我感觉自己像一个noob，我得到了下面的错误文件“traffic.py”，第13行，打印为“Current Listeners:”，res.text[pos+2:]NameError:name“res”没有定义非常抱歉，这是我的错误，现已修复。它应该是

span.text

，而不是

res.text

。哈哈哈

pos = res.text.find(': ')
res.text[pos+2:]
