Help with Regex

Post by Scones » Thu Nov 07, 2019 11:51 am

Hello

Can anyone figure this one out? Here is my string:

Esko ArtiosCAD - [TEST - 0 mfg]

This text is always the same
This text is always different
This is the text i need to get

I have never used regex before, so i'm very lost here.

This regex returns "everything between"

Code: Select all

//To help you understand
let>mystring=Esko ArtiosCAD - [TEST - 0 mfg]
let>BEGINNING=0 
let>END=]
RegEx>(?<=%BEGINNING%).*?(?=%END%),mystring,0,matches,nm,0
MessageModal>%nm% matches %CRLF%The item number is %matches_1%

//All condensed into one line
RegEx>(?<=0 ).*?(?=]),Esko ArtiosCAD - [TEST - 0 mfg],0,matches,nm,0
MessageModal>%nm% matches %CRLF%The item number is %matches_1%

Also, here's a free Regex course. It helped me grasp a basic understanding.

Thank you Dorian. Very helpful.

One more question: How would you write it, if you wanted to define "End" like you did, but instead of defining the Beginning, you just want to start from the beginning of the string?

This question is unrelated to my first question. I don't need to do that in that code .

So "everything in front of" instead of "everything between"?. Maybe one of the Regex gurus in here can show you that in Regex, but you don't need regex for that. Macro Scheduler can do that with Position, Length, and Midstr.

Get everything before G :

Code: Select all

Let>MyString=ABCDEFGHIJKLMNOPQRSTVUWXYZ

Len>MyString,MyStringLen
Pos>G,MyString,1,PosChar,
Midstr>MyString,1,{(%Poschar%-1)},MyNewString

MessageModal>MyNewString

@Scones,

Here is a RegEx that will grab what you need.

Code: Select all

let>mystring=Esko ArtiosCAD - [TEST - 0 mfg]

RegEx>^.* \[.* - 0 (.*)\],mystring,0,match,nom,1,$1,TextYouNeed

mdl>%TextYouNeed%

^ = start of string
.* = every character 0 or more times (up to the next specified character) Which is [.
\[ = Because RegEx uses [ in arguements, we use \ to let regex know it's part of what we are looking for.
.* = every character 0 or more times (up to the next specified character)
- 0 = text we are expecting. Literal.(There is a space before the hyphen(-). A space is a character.)
() = tells regex to remember what is between these parentheses. It's called a group.
(.*) = remember everything in this group (up to the next specified character) Which is ].
\] = same as [

Hope this helps,

The immensity of the scope of possibilities within Macro Scheduler pushes the user beyond just macros!
