我正在尝试将一个'& nbsp'添加到Beautifulsoup标签中。 BS将tag.string
转换为\ 
而不是 
。它必须是一些编码问题,但我无法弄明白。
请注意:忽略后面的'\'字符。我必须添加它,所以stackoverflow会正确地格式化我的问题。
import bs4 as Beautifulsoup
html = "<td><span></span></td>"
soup = Beautifulsoup(html)
tag = soup.find("td")
tag.string = " "
当前输出为html =“\&amp; amp; nbsp;”
有什么想法吗?

尽管如果您不介意使用formatter=None
,alecxe的the answer也可以使用,但是如果您想将
插入您要执行的某些HTML中,则没有用
"html5"
或"html"
)。
我发现Muposat使用"\xa0"
的{{3}}对我有用。
因此,要适应alecxe的答案:
from bs4 import BeautifulSoup
html = "<td><span></span></td>"
soup = BeautifulSoup(html, "html.parser")
tag = soup.find("span")
tag.string = "\xa0"
print soup.prettify(formatter="html5")
打印:
<td>
<span>
</span>
</td>
这是使用python 3.7。

默认情况下,BeautifulSoup
使用minimal
输出格式化程序并转换HTML实体。
解决方法是将输出格式化程序设置为None
,引用BS源代码(PageElement
docstring):
# There are five possible values for the "formatter" argument passed in
# to methods like encode() and prettify():
#
# "html" - All Unicode characters with corresponding HTML entities
# are converted to those entities on output.
# "minimal" - Bare ampersands and angle brackets are converted to
# XML entities: & < >
# None - The null formatter. Unicode characters are never
# converted to entities. This is not recommended, but it's
# faster than "minimal".
示例:
from bs4 import BeautifulSoup
html = "<td><span></span></td>"
soup = BeautifulSoup(html, 'html.parser')
tag = soup.find("span")
tag.string = ' '
print soup.prettify(formatter=None)
打印:
<td>
<span>
</span>
</td>
希望有所帮助。

您需要添加unicode非中断空间,可以表示为&#34; \ xa0&#34;在python:
soup = BeautifulSoup("", "html5lib") # html5lib will add html and body tags by default
soup.body.string = "\xa0" # uncode non-breaking space
soup.encode("ascii") # to see final html in ascii encoding
结果:
b'<html><head></head><body> </body></html>'
