In using the following PowerShell Script with Regex.
THE PROBLEM: I don't get any data returned for the Filename.
CURRENT RESULTS IN POWERSHELL:
EXPECTED RESULTS IN POWERSHELL:
This Regex Demo is doing what I would think it should be doing in Regex. (Originating from this question.)
POWERSHELL SCRIPT:
$InStuff = #('111111_SMITH, JIM_END TLD 6-01-20 THR LEWISHS.pdf','222222_JONES, MIKE_G URS TO 7.25 2-28-19 SA COOPSHS.pdf')
switch -Regex ($instuff) {
'^(^.{0,6})*|(?!.*_).*(?=\.)'{
[pscustomobject]#{
EmployeeID = $matches.1
FileName = $matches.2
}
}
}
QUESTION:
What do I need to change to get the filename to show up in the PowerShell results?

Answer 1

Seems like a simple .Split() can achieve what you're looking for. The method will split the string into 3 tokens which then get assigned to $a for the EmployeeID, $null for the User (we use $null here to simply ignore this token since you have already stated it was not of interest) and $b for the FileName. In PowerShell, this is known as multiple assignment.
To remove the extension from the $b token, as requested in your comment, regex is also not needed, you can use Path.GetFileNameWithoutExtension Method from System.IO.
$InStuff = #(
'111111_SMITH, JIM_END TLD 6-01-20 THR LEWISHS.pdf'
'222222_JONES, MIKE_G URS TO 7.25 2-28-19 SA COOPSHS.pdf'
)
foreach($i in $InStuff) {
$a, $null, $b = $i.Split('_')
[pscustomobject]#{
EmployeeID = $a
FileName = [System.IO.Path]::GetFileNameWithoutExtension($b)
}
}
Which results in:
EmployeeID FileName
---------- --------
111111 END TLD 6-01-20 THR LEWISHS
222222 G URS TO 7.25 2-28-19 SA COOPSHS
