RE: [powershell] Remove anything between defined characters:

[Michael B. Smith]

Your last line needs to be $b.Trim(). ☺

But if you want to go old-school about it:

$str.Remove( $str.IndexOf( '(' ), $str.IndexOf( ')' ) - $str.IndexOf( '(' ) + 
1).Trim()

Of course, I would never put such an abomination into production, primary 
because it assumes that both ( and ) exist. But I would do this, without 
hesitation:

$startIndex = $str.IndexOf( ‘(‘ )
$stopIndex = $str.IndexOf( ‘)’ )
$result = $str

if( $startIndex –ge 0 –and $stopIndex –ge 0 )
{
               $result = $str.Remove( $startIndex, $stopIndex - $startIndex + 1 
).Trim()
}

$result

I’m forced to say, after 35 years in IT, I still can only write the simplest of 
regexes. Perhaps I’ll learn how before I retire. ‘Cuz Devin’s solution is very 
slick.

Which is much better than my way, but here it is anyway ☺ since it takes a 
different approach.

$a = "Jessica (Yvonne)"
$b = ""
for ($i = 0; $i -lt $a.length; $i++) {
    if ($a[$i] -eq "(") {$Delete = $true}
    if ($a[$i] -eq ")") {$Delete = $false}
    if (-not $Delete -eq $true -and $a[$i] -ne ")") {$b = $b + $a[$i]}
}
$b.TrimEnd()

I would do it this way because i'm lazy:
 -replace " ?\(.*?\) ?"

PS > "(ywfew) Jessica (Yvs)" -replace " ?\(.*?\) ?"
Jessica
PS > "(ywfew)Jessica (Yvs)" -replace " ?\(.*?\) ?"
Jessica
PS > "Jessica (Yvs)" -replace " ?\(.*?\) ?"
Jessica

I’m working on a script that gets some data fed into it. Some of the fields 
have two names, one wrapped in (). Example: “Jessica (Yvonne)”. I am trying to 
remove everything within the (), but I’m not sure how. I’ve tried several regex 
expressions, and I’m able to remove the (), but not the content within them. 
Essentially I’d like to turn “Jessica (Yvonne)” into “Jessica” (even if there 
is whitespace after ‘Jessica’).

I tried several suggestions I saw online, escaping the “(“ and “)”, or using 
$regex = [regex]::Escape('()'), but I’m not sure how to basically say “Find ‘(‘ 
and remove everything until ‘)’ [including the parenthesis].

Any helpful tips or links where people are doing this? I tried doing array 
matches, removing the () and then selecting only the first position, but then 
discovered some of the fields have the parenthesis first (e.g. “(Yvonne) 
Jessica”.

Thanks for any suggestions.
