string - Extract a substring using PowerShell

Question

How can I extract a substring using PowerShell?

I have this string ...

"-----start-------Hello World------end-------"

I have to extract ...

Hello World

What is the best way to do that?

Answer 1

The -match operator tests a regex, combine it with the magic variable $matches to get your result

PS C:> $x = "----start----Hello World----end----"
PS C:> $x -match "----start----(?<content>.*)----end----"
True
PS C:> $matches['content']
Hello World
