I am appearrently too stupid to do RegEx in Powershell - help!

[oynaz]

Hi guys,

This should be a really simple problem. In my script, I need to extract a servername from a string.

String goes like

\\SERVERNAME\Sharename\Directory\Directory\

I think Regex is the easiest way to do this, but I cannot figure out how to do it.

I have tried:

$FullString = '\\SERVERNAME\Sharename\Directory\Directory\'
$ServerString = $FullString -match "\\\?\\"

and

$FullString = '\\SERVERNAME\Sharename\Directory\Directory\'
$ServerString = $FullString -replace "\\\?\\" ""

But this did not work, and both my Google-Fu and my brain seems defective right now.
Help!

By the way, I can also get this string as an object from an XML file, if it is easier to use Regex on an object.

It looks like the regex is the problem. Try something like this:

(?<=\\{2}).*?(?=\\)

Thanks for your help, and sorry about the long reply. I went on vacation

Your, regex is correct I believe, and I have managed to get it to do the exact opposite of what I wanted ;-)

$FullString = '\\SERVERNAME\Sharename\Directory\Directory\'
$ServerString = $FullString -replace "(?<=\\{2}).*?(?=\\)", ""

This removes the servername from the string, returning

\\\Sharename\Directory\Directory\

I cannot figure out how to do it the other way 'round.

-match returns a boolean, right. Is there another operator I should use?

Hmm, I might able to use the split-path cmdlet instead of regex. If it was a file path instead of an UNC path, I could simply go:

split-path $fullstring -qualifier

However, this does not work with UNc paths. Does anyone know of an UNC version of -qualifier? I cannot find it with get-help.

I found a solution here:

My code:

$FullString = '\\SERVERNAME\Sharename\Directory\Directory\'
$ServerString = [regex]::match(“$FullString”,’[^\\]+’).value
