Combine multiple Regular Expressions in Attachment macro

Combine multiple Regular Expressions in Attachment macro

Hi, I have a attachment macro and want some files NOT displayed.

I have 3 regular expressions that work fine if I use every one of them alone

^((?!.*[Ss][Dd][Ss]*.*).)*$,

^((?![Ee][Ss].*).)*$,

^((?![Ss]pec.*).)*$

I combined them in one and that didnt work because of the "$" - it says here ist the end of the expression.

So I came up with

^((?!.*[Ss][Dd][Ss]*.*).)*, ^((?![Ee][Ss].*).)*, ^((?![Ss]pec.*).)*$

Still not working.

I think the comma is used as a (text1|text2) OR expression in the background. I don't know.

Any ideas?

Hi Lars,

The expression should look like this:

^((?=(?!.*[Ss][Dd][Ss]*.*))(?=(?![Ee][Ss].*))(?=(?![Ss]pec.*)).)*$

I recognized a small problem.

I have these two files which are not listed:

Information_questionnaire_ecolabel_declaration_raw_materials_Jungbunzlauer_en_150828.pdf
Statement_questionnaire_ecolabel_declaration_raw_materials_Jungbunzlauer_en_150828.pdf

It is because of the (?=(?![Ee][Ss].*) part.

It recognizes the es in the middle of "questionnaire". I thought the filter says that the word must start with [Ee][Ss].

What would be the correct syntax to filter es* at the start of a filename?

I am not good at these...but after reading parts of this thread: https://stackoverflow.com/questions/406230/regular-expression-to-match-a-line-that-doesnt-contain-a-word

I added a point at the end (.*$)

here the complete regex:

^((?=(?!.*[Ss][Dd][Ss]*.*))(?=(?![Ee][Ss].*))(?=(?![Ss]pec.*)).).*$

for this special case the solution works. but I'm not quite sure if it fits every situation.
