help you fix your problem I am trying to color only the string "None Provided" versus the whole line. , Use multiple write-host with the -nonewline switch
code :
write-host "Managing Group: " -nonewline
write-host "None Found" -foreground red -nonewline
write-host "Group Description: None Provided"

Hope this helps Here is an extension method that overloads the AppendText method with a color parameter:
code :
public static class RichTextBoxExtensions
{
    public static void AppendText(this RichTextBox box, string text, Color color)
    {
        box.SelectionStart = box.TextLength;
        box.SelectionLength = 0;

        box.SelectionColor = color;
        box.AppendText(text);
        box.SelectionColor = box.ForeColor;
    }
}
var userid = "USER0001";
var message = "Access denied";
var box = new RichTextBox
              {
                  Dock = DockStyle.Fill,
                  Font = new Font("Courier New", 10)
              };

box.AppendText("[" + DateTime.Now.ToShortTimeString() + "]", Color.Red);
box.AppendText(" ");
box.AppendText(userid, Color.Green);
box.AppendText(": ");
box.AppendText(message, Color.Blue);
box.AppendText(Environment.NewLine);

new Form {Controls = {box}}.ShowDialog();

this one helps. I'm not quite sure what you're trying to achieve. Do you want to switch two values without a buffer variable? Or do you want to toggle a value between two states? The latter can be achieved like this:
code :
function Toggle($s, $v1, $v2) {
  $e1 = [regex]::Escape($v1)
  $e2 = [regex]::Escape($v2)

  $r = $s
  if ($s -match $e1) {
    $r = $s -replace $e1, $v2
  } elseif ($s -match $e2) {
    $r = $s -replace $e2, $v1
  }

  return ($r)
}

$foo = "..."

Toggle $foo "\\servername\folder\" "\\servername\"

I wish this help you The -replace operator only replaces the part of the string that matches. A capture group matches some subset of the match (or all of it), and the capture group can be referenced in the replace string as you've seen.
Your second example only ever matches that part you want to extract. So you need to ensure that you match the whole string but only capture the part you want to keep, then make the replacement string match your capture:
code :
$string2 = '1_123456_1'
$program2 = $string -replace '\d_(\d{6})_\d','$1'
$program2
1_(\d{6})_1
[^_]*_(\d{6})_[^_]*
^.*?(\d{6}).*?$

hope this fix your issue If you just want to remove any number of empty spans use a Regular Expression with a group and a quantifier:
code :
$original_file = 'in.txt'
$destination_file = 'out.txt'

(Get-Content $original_file) -replace "(<span>)+(</span>)+" | 
 Set-Content $destination_file

this will help I did it. What I did was find the numbers using regex and used Spannable in the while loop of the matches.find() to color the index of the matches. The start was the index and the end index + 2.
