正则匹配不包含某些关键词？

http://www.xxx.com/test/test.html
http://www.xxx.com/test/test2.html
http://www.xxx.com/ok/ok.html
http://www.xxx.com/ok/ok2.html
http://www.xxx.com/ok/ok3.html
http://www.xxx.com/try/try.html
http://www.xxx.com/try/try2.html
http://www.xxx.com/try/try3.html
http://www.xxx.com/trial/trial.html
http://www.xxx.com/trial/trial2.html
……
假设文件里有这些url，需要匹配非test和非ok的其他地址（也就是除了前五条以外的其他地址），请问python怎么实现？

import re

text = """

findList = \
re.findall("http:\/\/www\.xxx\.com\/(?!test)(?!ok)[a-z]*\/[a-z0-9]*\.html",
        text)

for string in findList:
    print(string)
