I don't know how you're accessing tag but the following works for me:

import BeautifulSoup  if __name__ == "__main__":     data = """  
some title
 
Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
    
Aliquam tincidunt mauris eu risus.
    
Vestibulum auctor dapibus neque.
 
      """     soup = BeautifulSoup.BeautifulSoup(data)     h2 = soup.find('h2')     h2.name = 'h1'     print soup 

Output of print soup command is:

 
some title
 
Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
 
Aliquam tincidunt mauris eu risus.
 
Vestibulum auctor dapibus neque.
 

As you can see, h2 became h1. And nothing else in the document changed. I am using Python 2.6 and BeautifulSoup 3.2.0.

If you have more than one h2 and you want to change them all, you could simple do:

soup = BeautifulSoup.BeautifulSoup(your_data) while True:      h2 = soup.find('h2')     if not h2:         break     h2.name = 'h1'

It's just:

tag.name = 'new_name'

From BeautifulSoup docs

from BeautifulSoup import BeautifulSoup, Tag soup = BeautifulSoup("
TEXTHERE
") tag = Tag(soup, "h1", [("class", "someclass")]) tag.insert(0, "TEXTHERE") soup.h2.replaceWith(tag) print soup # 
TEXTHERE
