Beautifulsoup split text in tag by <br/>

问题

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

I have this tag contents: [u'+420 777 593 531', <br/>, u'+420 776 593 531', <br/>, u'+420 775 593 531']

And I want to get only numbers. Any advices?

EDIT:

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

Does not work at all.

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']

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)

Demo:

>>> from bs4 import BeautifulSoup
>>> soup = BeautifulSoup('''\
... <dt>Term</dt>
... <dd>
...     +420 777 593 531<br/>
...     +420 776 593 531<br/>
...     +420 775 593 531<br/>
... </dd>
... ''')
>>> dt = soup.dt
>>> [x for x in dt.find_next_sibling('dd').contents if getattr(x, 'name', None) != 'br']
[u'\n    +420 777 593 531', u'\n    +420 776 593 531', u'\n    +420 775 593 531', u'\n']
>>> list(dt.find_next_sibling('dd').stripped_strings)
[u'+420 777 593 531', u'+420 776 593 531', u'+420 775 593 531']
