Hoo*_*ked 8 python xml beautifulsoup xml-parsing
这个问题特定于BeautifulSoup4,这使得它与以前的问题不同:
BeautifulSoup中的selfClosingTags
既然BeautifulStoneSoup已经消失了(以前的xml解析器),我怎样才能bs4尊重新的自闭标签？例如:
import bs4
S = '''<foo> <bar a="3"/> </foo>'''
soup = bs4.BeautifulSoup(S, selfClosingTags=['bar'])
print soup.prettify()
不会自动关闭bar标签,但会给出提示.bs4所指的这个树构建器是什么以及如何自我关闭标记？
/usr/local/lib/python2.7/dist-packages/bs4/__init__.py:112: UserWarning: BS4 does not respect the selfClosingTags argument to the BeautifulSoup constructor. The tree builder is responsible for understanding self-closing tags.

要解析XML,请将"xml"作为BeautifulSoup构造函数的第二个参数传递.
soup = bs4.BeautifulSoup(S, 'xml')
你不需要再通过selfClosingTags了:
In [1]: import bs4
In [2]: S = '''<foo> <bar a="3"/> </foo>'''
In [3]: soup = bs4.BeautifulSoup(S, 'xml')
In [4]: print soup.prettify()
<?xml version="1.0" encoding="utf-8"?>
<foo>
<bar a="3"/>
</foo>
