Selecting particular elements of output when using Split

Hi
I'm trying to extract just the machine name from the Key Management Service event log in realtion to activation requests. What I've got so far is:
$entries = Get-EventLog 'Key Management Service' | ? {$_.InstanceId -eq '12290'}
foreach($entry in $entries)
{
($entry.Message).Split(",")
}but then I want to only display the 5th line of the output (which is where the name of the machine initiating the activation request is shown).
I thought that maybe I could treat it as an array and then select the relevent element but so far my attempts have drawn a blank.
Any assistance in this would be most appreciated and apologies if this has already been answered elsewhere and I simply haven't found it yet!

Since I do not have that eventlog myself I cannot run the script here, but if you only want to display the 5th line you could just throw a counter in there:
$entries = Get-EventLog 'Key Management Service' | ? {$_.InstanceId -eq '12290'} foreach($entry in $entries) { $i = 0 ($entry.Message).Split(",") | % {$i++;if ($i -eq 5) {write-host $_} } }

Thanks Jaap. Turns out that due to the formatting it was actually the 3rd proper line but changing ($i -eq 5) to ($i -eq 3) got it working.
Much appreciated.

This is all you need to do to get a specific element.
$entry.Message).Split(",")[4]
Just subscript the line and it will give you that element.
¯\_(ツ)_/¯
