editpad regex. Searching files for "http://" but excluding "http://particular.domain.com"

Question

I'm using RegexBuddy and getting nowhere defining a search parameter for editpad.

I'm trying to search through my CMS web site for all instances of "http://" (to see where the protocol was hardcoded incorrectly), but every file has "http://particular.domain.com" in the comments near the top of the file.

How can I search for all EXCEPT those? This seems like it should be basic.

Answer 1

Here's your expression:

http:\/\/(?!particular\.domain\.com).+

This portion is called a negative lookahead that lets you negate that match:

(?!particular\.domain\.com).+

Answer 2

use a negative lookahead:

'(?!http://particular.domain.com)http://'

is an example of a pattern that would match any http:// text EXCEPT the particular one
