PowerShell: Change 2 specific string into .ini - string

Question

I'm searching to replace 2 occurrences of a specific string but each by one data different.
Here the file with 2 lines :
[SERVER1]
NAME = SERVER1\SQLEXPRESS
ODBCLINK = idms
USER = idms
PSW = idms
[SERVER2]
NAME = SERVER2\SQLEXPRESS
ODBCLINK = backupidms
USER = idms
PSW = idms
For the moment I have that code:
Get-Content ".\test.ini") | ForEach-Object { $_ -replace ".+\SQLEXPRESS" , "Name = $hostname\SQLEXPRESS" } | Set-Content ".\test.ini"
The goal is to have that :
[SERVER1]
NAME = Paris\SQLEXPRESS
ODBCLINK = idms
USER = idms
PSW = idms
[SERVER2]
NAME = Nantes\SQLEXPRESS
ODBCLINK = backupidms
USER = idms
PSW = idms
I read these 2 strings, Paris and Nantes, from another file.
Test1 and TEst2 can be ALieoej and PAodj45p. it's arbitrary choice
I think i need a script to search one line with sqlexpress into, and change it by one data, and the second time where i find it, replace it by another data

Answer 1

Seems like this may be what you are looking for. This will CREATE the test.ini file instead of editing it as you asked.
Set-Content -Value "Test1
Test2" -Path computers.txt
(Get-Content ".\computers.txt") | ForEach-Object {"Name = $_\SQLEXPRESS" } | Set-Content ".\test.ini"
Where computers.txt is your source of computers that have SQL Express instances.

Hi i found myself a solution :
rm $fichierDest
$content = get-content $fichierSource
$i = 0
while($i -lt $content.Length - 1)
{
$line = $content[$i]
$line2 = $content[$i+1]
if($line -match "SERVER1")
{
$line2 = $line2 -Replace ".+\SQLEXPRESS" , "Name = TEST1\SQLEXPRESS"
add-content $fichierDest $line
add-content $fichierDest $line2
$i += 2
}
elseif($line -match "SERVER2")
{
$line2 = $line2 -Replace ".+\SQLEXPRESS" , "Name = TEST2\SQLEXPRESS"
add-content $fichierDest $line
add-content $fichierDest $line2
$i += 2
}
else
{
add-content $fichierDest $line
$i++
}
}
