Solve the following python programming problem given the following code:
def keeptags(value, tags) : 
    tags = [re.escape (tags) for tag in tags.split ()] 
    def _replacer(match) : 
        if (match.group (1) in tags) : 
            return match.group (0) 
else : 
            return '' 
return re.sub ('</?([^>]+).*?>', _replacer, value)
