@Doitsu...Interesting what you say about Kindle. Their's is a proprietary format that is closely related to epub with some peculiar quirks. Similar to iBooks proprietary version of epub. You can do that if you are a mammoth company like those two.

Here's another piece of BS code for html that I've found very useful:

Spoiler:

    # remove all anchors but preserve 
    # all anchors with internet links    
    for m in soup.findAll('a'):
        if 'href="http:' in str(m) or \
           'href="https:' in str(m) or \
           'mailto:' in str(m) or \
           '@' in str(m):
            pass            
        else:
            m.replaceWithChildren()

In my conversion plugin, I've also noticed significant differences between ODF html rendered from OO and LO. One problem I had was clearing out all the myriad FONT, FACE and SIZE declarations in these two different ODF html versions.

I used this code to remove all SIZE = 3 attributes from the html because it was causing problems. Notice that OO uses an integer while LO uses a string numeric for the size value.

Spoiler:

    # remove all 'size = 3' font declarations from OO or LO html       
    for x in soup.findAll('font'):
       if x.has_attr('size'):
           if x['size'] == "3" or x['size'] == 3:
               x.replaceWithChildren()

Both Tidy and BS have saved my bacon on many occasions. They are both remarkably useful and easy to use for processing html.
