How can I match all strings without the word "authorize" in them via regular expressions? I tried *(authorize){0}* to no avail.

1you should invest an hour and read the tutorials, e.g. http://www.regular-expressions.info/ ; your pattern makes no sense. – polygenelubricants Jul 05 '10 at 16:37

/^(?!.*authorize).*/
This uses a negative lookahead to ensure that the overall pattern will match only if the expression "authorize" cannot match anywhere in the input.

Most modern regex engines implement positive and negative lookahead assertions. – Amber Jul 05 '10 at 17:58
