PowerShell中获取多行代码

Question

I want to get the multiple lines from a text file by using a pattern with the character at the beginning of the string to the character at the end of the string,and have an output that will be copied as multiple lines also.

<#
  get
  these
  lines
#>

I have tried using regex "<#(.+)#>", it gets the lines but it copies as one string only.

Output: <# get these lines #>

Answer 1

FileLines3.TXT:

Random info1
<#
  get1
  these1
  lines1
#>
Random info2
<#
  get2
  these2
  lines2
#>
Random info3

Code:

$FileContent = Get-Content -Path "$PSScriptRoot\FileLines3.TXT" -Raw
$Lines = while($FileContent -match '(?ms)^\s*<#\s*$(?<Block>.*?)#>\s*$(?<After>.*)') {
    $Matches.Block.Split([Environment]::NewLine)
    $FileContent = $Matches.After
}
$Lines | Where-Object {$_}

Results:

  get1
  these1
  lines1
  get2
  these2
  lines2
