如何在BeautifulSoup.BeautifulStoneSoup中维护区分大小写的标签？

Question

我正在编写一个用于编辑XML文件的脚本BeautifulStoneSoup,但该库会将所有标记转换为小写.是否可以选择保存案例？

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>

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

In [14]:
