Problem with replace with

Hello,

I have a big problem with Beautifull soup's replaceWith not working:

I have something like xxx and want it to be replaced by xxx

my code:

Code:

    def preprocess_html(self, soup):

        # Change 
        for fett in  soup.findAll(name='span',attrs={'class':'ngen_F'}) :
            if fett:
                tag = Tag(soup, 'b')
                tag.insert(0, fett.contents[0])
                print tag
                fett.replaceWith(tag)

        return soup

print tag works. But replaceWith just replaces with ''
When I do fett.replaceWith('test) this is ok.

What's wrong here?

Stefan

I had exactly the same problem yesterday when i was trying to insert a Tag. I don't think it's worth worrying about - might as well just use what works and pass a simple HTML string to insert/replaceWith. Tag objects don't seem to work the way BeautifulSoup's documentation says they do.
