I have some values

x64\3\Cardreaders\VIA\WIN7\x64
x64\Win8\L\Realtek\2\Win8
Gaming_x64_812\1\1

I want to return only the first match between the characters, using StringRegExpReplace, because I have further questions regarding this.

I have tried (.*?) however I only need the first match. Also I do not need to create an array.

$string = "Gaming_x64_812\1\1"
$match = StringRegExpReplace($string, "\\(.*?)\\")
ConsoleWrite("$match: "&$match&@CRLF)

Not sure what you are using this for, but I'd just use StringSplit and use the second value.

$value = StringSplit("x643CardreadersVIAWIN7x64", "")

$result = $value[2]

$value = StringSplit("x643CardreadersVIAWIN7x64", "")

$result = $value[2]

 

Thank you, however some strings are a bit more complex, and I also need to do another comparison, which will be the last match between the characters, eg

x64\3\Cardreaders\VIA\WIN7\x64
x64\Win8\L\Realtek\2\Win8
Gaming_x64_812\1\1

Where I would want to return

WIN7
2
1

So I thought asking about a stringregexpression would be useful for learning, how to do this.

Thanks for your help everyone so far. I am nearly there.

Kind regards

Just remove the first ? in Malkey's example and you will get the last match.

Local $match = StringRegExpReplace($string, ".*\\(.+?)\\.*", "\1")

Local $string = "x64\3\Cardreaders\VIA\WIN7\x64" & @CRLF & _
        "x64\Win8\L\Realtek\2\Win8" & @CRLF & _
        "Gaming_x64_812\1\1" & @CRLF & _
        "Gaming_x64_812\HI\hey\1234444\1"


Local $match = StringRegExpReplace($string, ".*?\\(.+?)\\.*", "\1")     
ConsoleWrite("first $match:- " & @CRLF & $match & @CRLF& @CRLF)     

Local $match = StringRegExpReplace($string, ".*\\(.*?)\\.*", "\1")      
ConsoleWrite("second $match:- " & @CRLF & $match & @CRLF)

Great, thanks for the help everyone, this script does the job.

What can I say, I always go for the simple approach.  ;)

Nothing wrong with learning and trying some nifty RegEx if that's your thing though.  :D

We should probably devote a part of the forum to RegEx ... maybe I'd even start using it a lot more.  :P

P.S. Yes I know about the Wiki.  ;)  ;)
