如何在BeautifulSoup.BeautifulStoneSoup中維護區分大小寫的標籤？

Question

我正在編寫一個腳本，它用BeautifulStoneSoup編輯XML文件，但該庫將所有標記轉換爲小寫。有沒有辦法保存案件？

import BeautifulSoup  
xml = "<TestTag>a string</TestTag>"  
soup = BeautifulSoup.BeautifulStoneSoup(xml, markupMassage=False)  
print soup.prettify() # or soup.renderContents() 
#prints 
>>> <testtag>a string</testtag> 
#instead of the expected 
>>> <TestTag>a string</TestTag>

你可以使用Beautiful Soup 4，如下（需要lxml的XML庫）：

In [10]: from bs4 import BeautifulSoup 

In [11]: xml = "<TestTag>a string</TestTag>" 

In [12]: soup = BeautifulSoup(xml, "xml") 

In [13]: print soup 
<?xml version="1.0" encoding="utf-8"?> 
<TestTag>a string</TestTag> 

In [14]:
