StringRegExp Help

[Fitgo]

I would like to find a way to give back all the way before: Application

With: C:Program Files (x86)GoogleChromeApplicationApplicationApplicationApplicationApplicationApplication33.0.1750.154Installersetup.exe

Return: C:Program Files (x86)GoogleChromeApplicationApplicationApplicationApplicationApplicationApplication

With: C:Program Files (x86)GoogleChromeApplication33.0.1750.154Installersetup.exe

Return: C:Program Files (x86)GoogleChromeApplication

Use StringRegExp. Thanks for help.

(?U)[[:alpha:]]:\\

then I do not know how to continue

[jguinch]

$sString = "C:\Program Files (x86)\Google\Chrome\Application\Application\Application\Application\Application\Application\33.0.1750.154\Installer\setup.exe"
$sResult = StringRegExpReplace($sString, "(.*Application\\).*", "$1")
ConsoleWrite($sResult & @CRLF)

$sString = "C:\Program Files (x86)\Google\Chrome\Application\33.0.1750.154\Installer\setup.exe"
$sResult = StringRegExpReplace($sString, "(.*Application\\).*", "$1")
ConsoleWrite($sResult & @CRLF)

Like this?

Local $path = "C:\Program Files (x86)\Google\Chrome\Application\Application\whatever else...\Application\Application\Application\Application\33.0.1750.154\Installer\setup.exe"
Local $root = StringRegExpReplace($path, "(.*\\Application\\)(.*)", "$1")
ConsoleWrite($root & @LF)

[jguinch]

Well, I forget the "" before Application...Fortunately, JC has been there

Can also be $sResult = StringRegExpReplace($sString, "(?i)(.*Application).*", "$1")

Thanks to both of you. I solved with the solution of jchd.

However, if I want to take only the letter of the partition on? 

Example: $%&''C:Program Files (x86)GoogleChromeApplicationApplicationwhatever else...ApplicationApplicationApplicationApplication33.0.1750.154Installersetup.exe

Return: C:Program Files (x86)GoogleChromeApplicationApplicationwhatever else...ApplicationApplicationApplicationApplication

Should I implement something like this: (?U)[[:alpha:]]

How do I?

Thanks for help.

[jguinch]

Yes, something like

$sLetter = StringRegExpReplace($sString, "(?i).*([[:alpha:]]):.*", "$1"),

or just $sLetter = StringRegExpReplace($sString, "(?i).*([A-Z]):.*", "$1")

Local $path = "$%&'a:(not there!)@'C:\Program Files (x86)\Google\Chrome\Application\Application\whatever else...\Application\Application\Application\Application\33.0.1750.154\Installer\setup.exe"
Local $root = StringRegExpReplace($path, "(?i).*((?<![a-z])[a-z]:(?=\\).*\\Application\\)(.*)", "$1")
ConsoleWrite($root & @LF)

[mikell]

jc, isn't this good enough ?

Local $root = StringRegExpReplace($path, "(?i).*([a-z]:\\.*\\Application\\).*", "$1")

(because of the greediness of the first .* )

I was protecting against this case (unlikely in the samples shown but more robust in the general case):

Local $path = "$%&'a:(not there!)@'C:\Application\33.0.1750.154\Installer\setup.exe"
Local $root = StringRegExpReplace($path, "(?i).*([a-z]:\\.*\\Application\\).*", "$1")
ConsoleWrite($root & @LF)

[mikell]

OK this makes the lookahead clear, but what about the lookbehind ?

StringRegExpReplace($path, "(?i).*([a-z]:(?=\\).*\\Application\\).*", "$1")

[jchd]

Yes, as well. And like I just told jguinch in PM, it was what I came up with while watching my movie and monitoring the cooking of my home-made pizza.

Cat & skins, as usual.

Very thanks. I have solved.
