PowerShell Regex Number Increase

Question

I have files containing strings like

#define PROG_HWNR "#37595" #define C_HWPROG_NR "24499" #define PROG_HWNR "#39917" #define C_HWPROG_NR "24901" #define C_HWPROG_NR "37598" 

I put them in a file called regex-test (for testing purposes)

What I want to do is increase each number by one. There are other #defines and numbers that should not be increased, I have a list of all the variable names that need to be increased.

I already have a PowerShell command, for example

 Get-Content regex-test | foreach { [regex]::match($_,'"#?(\d+)"$').groups[1].value } 

which returns numbers. Now they need to be replaced only by [value] + 1

Can you point me in the right direction? Thanks!

Why not just:

 $tmp = Get-Content regex-test | foreach { $n = [regex]::match($_,'"#?(\d+)"$').groups[1].value; if ($n) {$_ -replace "$n", ([int32]$n+1)} else {$_}; } 

Then save $tmp .
