Hi,

I using RegexBuddy to test a java regex expression that will match any string except one with "abc" anywhere in the string.

I.e. Match any strings except the ones with "abc"

1) www.test.com/ad/click-imp/ref?=center=701&pf_rd_i=2&p
2) www.test.com/abc/click-imp/ref=center=701&pf_rd_i=2&p
3) www.test.com/inventory_rep2_mn=70/abc/ws_gh790?%5Fencoding=UTF8
4) www.test.com/promotion/h/ref=xg_2_center/gh_321?%5Fencoding=UTF8

So I want to match string 1 and 4 but not 2 and 3. I tried a bunch of expression but so far the closest I've come is www.test.com/([^abc]++).*

Can an expert help me out?

 Pattern re = Pattern.compile("^(?:(?!abc).)*$",Pattern.DOTALL);

Hi ddrudik,

I read a bunch of your other posts yesterday :)

I can't do the java commands because the application I'm using will only input regex. DOTALL and Pattern are taken literally.

(?s)^(?:(?!abc).)*$

or:

^(?:(?!abc)(?:.|\n))*$

or:

^((?!abc)(.|\n))*$
