Question

I am using regex in Powershell. I have a non-capturing group but it is still showing in my results.

String is:

Grid1.Data = [['TRE - Significant Flux','EG Report','w939909','59e8a31f-d9e9-4ebf-a027-929ec62953ac'],['CB - Daily OD Report','EG Report','w9
39909','59e8a31f-d9e9-4ebf-a027-929ec62953ac'],['BC - Balance Transfers Daily - DRAFT','BC - Balance Transfers Daily - DRAFT','w939909','59e8
a31f-d9e9-4ebf-a027-929ec62953ac'],['CB - CL Activity Report','CB - CL Activity Report','w939909','59e8a31f-d9e9-4ebf-a027-929ec62953ac']]

Regex is:

$regex = "(?:\[').*?(?=')"  

It is still returning things like [‘TRE – Significant Flux

I need to exclude the opening “[‘”. The non capturing group at the end for the single quote is working.

Answer 1

try using lookbehind assertion

$regex = "(?<=\[').*?(?=')"

or:

$regex = "(?:\[\[')(.*?)(?=')"

$yourstring -match $regex
