Regexp matching except

I'm trying to match some paths, but not others via regexp. I want to match anything that starts with "/profile/" that is NOT one of the following:

Here is the regex I'm trying to use that doesn't seem to be working:

^/profile/(?!attributes|essays|edit)$

For example, none of these URLs are properly matching the above:

comments are hard to read code in, so here is my answer in nice format

def mpath(path, ignore_str = 'attributes|essays|edit',anything = True):
    any = ''
    if anything:
        any = '.*?'
    m = re.compile("^/profile/(?!(?:%s)%s($|/)).*$" % (ignore_str,any) )
    match = m.search(path)
    if match:
        return match.group(0)
    else:
        return ''

You need to say that there can be any characters until the end of the string:

^/profile/(?!attributes|essays|edit).*$

Removing the end-of-string anchor would also work:

^/profile/(?!attributes|essays|edit)

And you may want to be more restrictive in your negative lookahead to avoid excluding /profile/editor:

^/profile/(?!(?:attributes|essays|edit)$)
