So I have a list

Code: Select all

Work
Work
Fire
Global


And I want just the first letters from each line.

Code: Select all

WWFG


The list is created by a batch script

Code: Select all

echo %1>>


I've tried this

Code: Select all

([a-z])[^\n]+\n*
but it gives me just an F

try:

Code: Select all

(?siU)(?(?=.)(.))(?(?=.*\n).*\n(.))(?(?=.*\n).*\n(.))(?(?=.*\n).*\n(.))



repeat the

Code: Select all

(?(?=.*\n).*\n(.))

as often as you need.

In this approach, if I don't know just exactly how many times I need to use it in advance it sometimes gives me nothing at all...


Nvm. It works flawlessly.
