How to cut the values till particular character?

I am having an array $IPAddress which contains IPv4 and IPv6 address like below.

IPAddress : {166.33.77.15, fe90::68fe:7602:d981:2cb}

IPAddress : {166.33.77.18, fe87::67c0:8476:3509:fb7a}

IPAddress : {166.33.77.65, fe80::c08e:f5ec:5095:e7ec}

I would like to store in my IPaddress array only the IPv4 address. I need to cut after '{' till ','. How to do this using powershell?

I got pretty much the same answer as Shay, but I'll add that you don't need to foreach the replace. It'll do the entire array at once:

$array -replace '^IPAddress : {([^,]+).+$','$1'

This is a way but I think (not... I'm sure!) there's something better using regex!

$IPAddress = $IPAddress | % { $_.Substring( $_.IndexOf('{')+1 , $_.IndexOf(',') - ($_.IndexOf('{')+1))

Edit: simple way with regex (not verifying if IP address is a valid ipaddress)

$IPAddress = $IPAddress |  select-string "\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}" | select -ExpandProperty matches | select -ExpandProperty value

You can use regular expressions in PowerShell very easily for this.

$IPAddress = @(`
    "IPAddress : {166.33.77.15, fe90::68fe:7602:d981:2cb}", `
    "IPAddress : {166.33.77.18, fe87::67c0:8476:3509:fb7a}", `
    "IPAddress : {166.33.77.65, fe80::c08e:f5ec:5095:e7ec}")

foreach($ip in $IPAddress) { 
    if ($ip -match "{.*,") {
        Write-Host $matches[0].substring(1, $matches[0].length - 2)
    }
}

$matches is a special variable which is set after using the -match operator.

If the result is an object then you can simply do:

$IPAddress[0]

If it's a string, try using a regex:

'IPAddress : {166.33.77.15, fe90::68fe:7602:d981:2cb}' -replace '^IPAddress : {([^,]+).+$','$1'
