Beautifulsoup在标签中用< br/>分割了文本 [英] Beautifulsoup split text in tag by <br/>

问题描述

是否可以通过br标签从标签中拆分文本?

Is it possible to split a text from a tag by br tags?

我有这个标签内容:[u'[phone]', <br/>, u'[phone]', <br/>, u'[phone]']

我只想得到数字. 有什么建议吗?

And I want to get only numbers. Any advices?

[x for x in dt.find_next_sibling('dd').contents if x!=' <br/>']

根本不起作用.

推荐答案

您需要测试标记为Element实例的标签. Element对象具有name属性，而文本元素则没有(NavigableText实例):

You need to test for tags, which are modelled as Element instances. Element objects have a name attribute, while text elements don't (which are NavigableText instances):

[x for x in dt.find_next_sibling('dd').contents if getattr(x, 'name', None) != 'br']

由于您似乎在该<dd>元素中仅包含文本和<br />元素，因此您也可能会得到

Since you appear to only have text and <br /> elements in that <dd> element, you may as well just get all the contained strings instead:

list(dt.find_next_sibling('dd').stripped_strings)

演示:

>>> from bs4 import BeautifulSoup
>>> soup = BeautifulSoup('''\
... <dt>Term</dt>
... <dd>
...     [phone]<br/>
...     [phone]<br/>
...     [phone]<br/>
... </dd>
... ''')
>>> dt = soup.dt
>>> [x for x in dt.find_next_sibling('dd').contents if getattr(x, 'name', None) != 'br']
[u'\n    [phone]', u'\n    [phone]', u'\n    [phone]', u'\n']
>>> list(dt.find_next_sibling('dd').stripped_strings)
[u'[phone]', u'[phone]', u'[phone]']
