有任何python lib可以做到这一点吗？

解决方案
  BeautifulSoup 几乎可以让你几乎在那里： 
 
 
 >>>导入BeautifulSoup 
>>> f = open（'a.html'）
>>>汤= BeautifulSoup.BeautifulSoup（f）
>>> f.close（）
>>> g = open（'a.xml'，'w'）
>>>打印>> g，soup.prettify（）
>>> g.close（）
  
这会正确关闭所有标签。剩下的唯一问题是 doctype 仍然是 HTML   - 要将其改为您选择的文档类型，仅限于您需要改变第一行，这并不难，例如，而不是直接打印经过批准的文本， 
 
 
 >> > lines = soup.prettify（）。splitlines（）
>>>行[0] =（'<！DOCTYPE html PUBLIC -  // W3C // DTD XHTML 1.0 Transitional // EN'
'http://www.w3.org/TR/xhtml1/DTD /xhtml1-transitional.dtd\">'）
>>>打印>> g，'\\\
'.join（lines）

 解决方案 
BeautifulSoup gets you almost all the way there:
>>> import BeautifulSoup
>>> f = open('a.html')
>>> soup = BeautifulSoup.BeautifulSoup(f)
>>> f.close()
>>> g = open('a.xml', 'w')
>>> print >> g, soup.prettify()
>>> g.close()

This closes all tags properly.  The only issue remaining is that the doctype remains HTML -- to change that into the doctype of your choice, you only need to change the first line, which is not hard, e.g., instead of printing the prettified text directly,
>>> lines = soup.prettify().splitlines()
>>> lines[0] = ('<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"'
                '"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">')
>>> print >> g, '\n'.join(lines)
