Hi everyone,

I have this string:

"main_lot      0x111” & @CRLF & “main_version          0xABC” & @CRLF & “main_number 0xDEAD123” & @CRLF & “main_version          0x333"

And I'm trying to extract one specific hexadecimal number, actually main_version from this string by using StringRegExp:
How to get 'ABC' from it?

  • I'm not sure if the original string uses @CRLF, @CR or @LF as a line breaks (received from linux over ssh plink.exe)

I have tried this code but it doesn't work  

#include <Array.au3>

$sLog = "main_lot      0x111” & @CRLF & “main_version          0xABC” & @CRLF & “main_number 0xDEAD123” & @CRLF & “main_version          0x333"
$aVer = StringRegExp($sLog, "main_version\h*(.+)(?:0[xX][[:xdigit:]])", 3)
_ArrayDisplay($aVer)

Thanx 🙂 ! It's work! 

For cleaner coding, can I catch only first matching of main_version?

Of course, just replace the 3 by 1 as last parameter.

Well worth the effort to try and understand the basics - it is a phenomenally powerful tool, as jchd has just shown.
