Django Middleware - How to edit the HTML of a Django Response object?

Question

I'm creating a custom middleware to django edit response object to act as a censor. I would like to find a way to do a kind of search and replace, replacing all instances of some word with one that I choose.

I've created my middleware object, added it to my MIDDLEWARE_CLASSES in settings and have it set up to process the response. But so far, I've only found methods to add/edit cookies, set/delete dictionary items, or write to the end of the html:

class CensorWare(object):
    def process_response(self, request, response):
        """
        Directly edit response object here, searching for and replacing terms
        in the html.
        """
        return response

Thanks in advance.

You can simply modify the response.content string:

response.content = response.content.replace("BAD", "GOOD")
