Powershell replace is duplicating results - powershell

Question

I have a simple script that is suppose to find text and if the right conditions are met, it will replace the text:
foreach ($line in $file){
$line.replace("â‡","+") | Out-File -FilePath $destination -Append
if ($line -eq "â‡RECORD_IDENTIFIER:"){
$line.replace("â‡RECORD_IDENTIFIER:","+RECORD_IDENTIFIER: A") | Out-File -FilePath $destination -Append
}
if ($line -eq "â‡END_TAG"){
$line.replace("â‡END_TAG","+END_TAG;") | Out-File -FilePath $destination -Append
}
but the result is this:
+START_TAG:
+DATA_FILE_(DATE/TIME):2017-02-13T13:44:44.489-08:00
+RECORD_IDENTIFIER:
+RECORD_IDENTIFIER: A
+CLIENT_NUM:8802
+SOLOMON_ID:TRUG01
I only want it to produce one RECORD_IDENTIFIER.

Answer 1

This is where you need to discover the Switch operator. I think it's an operator, maybe a cmdlet? Whatever it is, its what you need! What it does is compare the current iteration of a collection against multiple cases, and applies the cases that match. For example:
Switch ($file) {
"â‡RECORD_IDENTIFIER:" {
$_.Replace("â‡RECORD_IDENTIFIER:", "+RECORD_IDENTIFIER: A") |
Out-File -FilePath $destination -Append
Continue
}
"â‡END_TAG" {
$_.Replace("â‡END_TAG", "+END_TAG;") |
Out-File -FilePath $destination -Append
Continue
}
default {
$_.Replace("â‡", "+") |
Out-File -FilePath $destination -Append
}
}
The Continue commands tell the loop to move to the next item, so if it matches the first case it will do your replace, output it to file, and then move to the next line. If it does not match the first case it tries the second, and if it matches it will do the replace for that, output to file, and move to the next line. If it doesn't match either of the first two cases it reaches the default line, and everything has that scriptblock applied to it, so anything that didn't match the first two cases has the replace("â‡","+") performed, and output to file.
