Question

I have the next re using the c# regex class:

[^\r\n]+[^,"condicionesDePago"]

searching in the next text:

“CREDITO 30 DIAS”,”condicionesDePago”

I want to get the left part, in this case:“CREDITO 30 DIAS” but i only get : “CREDITO 30

what im missing?

Answer 1

It looks like you have a misunderstanding of what the character class is used for. It doesn’t operate on words, but rather on individual characters. This part of your pattern, [^,"condicionesDePago"] indicates that a character should be matched provided it is not a comma, double quotes, or specified alphabet in that word.

You probably intended to use a look-ahead:

@"[^\r\n]+(?=,""condicionesDePago"")"

Alternately, this could be written as follows and won’t match \n as long as RegexOptions.Singleline isn’t specified (but it can match \r):

@".+?(?=,""condicionesDePago"")";
