Exporting registry key and SETing the string

[Roeee]

Apologies if this is the wrong forum for the type of request.

I am attempting to export a registry string (REGEDIT /e or REG QUERY .logfile) to a text file and would like to specify the result as a SET variable. The problem is that the output text file has several lines of text rather than the required string (as such I can not select SET = field3 for example).

Is there any command I can use to output only the specified string? If not, is there a quick way I can select a registry string and SET as a variable for use within a batch file?

Thanks

not sure if im going to answer your question, but this sounds like something i wrote awhile back. i wrote a batch file to export the Un-Install string for installed apps on users pc's...i would have like to call the apps uninstall .msi file but the guid was different on each pc, so i exported the reg key that was unique to each pc.here it is:
REGEDIT /E :NEWFILE.reg "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\YOUR-APP-HERE"

FOR /F "TOKENS=1* delims==" %%A in ('TYPE c:NEWFILE.reg ^| FIND ":"') DO SET UI1=%%B
SET LINE1=%UI1:\\=\%
SET LINE1=%LINE1:\"="%
SET LINE1

FOR /F "DELIMS=" %%A IN ('%LINE1%') DO ECHO %%A

del "c:NEWFILE.reg" /q

What it does is exports the reg key. then finds the line of the key that has a ":" in it and sets it to UI1. then it removes the double backslashes \\, then changes any = to a \. Next it calls %Line1%, which is the un-install string, and it un-installs the app. then it will delete the .reg file it created.

Hope this Helps
