假设我有一个 HTML<p> and <br>里面有标签。之后，我将剥离 HTML 以清理标签。我怎样才能把它们变成换行符？
我正在使用Python的美丽汤 http://www.crummy.com/software/BeautifulSoup/图书馆，如果有帮助的话。
如果没有一些细节，很难确定这完全符合您的要求，但这应该给您一个想法......它假设您的 b 标签包含在 p 元素内。
from BeautifulSoup import BeautifulSoup
import six
def replace_with_newlines(element):
text = ''
for elem in element.recursiveChildGenerator():
if isinstance(elem, six.string_types):
text += elem.strip()
elif elem.name == 'br':
text += '\n'
return text
page = """<html>
<body>
<p>America,<br>
Now is the<br>time for all good men to come to the aid<br>of their country.</p>
<p>pile on taxpayer debt<br></p>
<p>Now is the<br>time for all good men to come to the aid<br>of their country.</p>
</body>
</html>
"""
soup = BeautifulSoup(page)
lines = soup.find("body")
for line in lines.findAll('p'):
line = replace_with_newlines(line)
print line
运行此结果...
