batch file for command parsing path

I am trying to read a file path into a Windows Batch file variable

set print_nodePath=reg query "hklm\software\node.js" /v InstallPath
for /f "skip=2 tokens=3" %%a in ('%print_nodePath%') do set nodePath=%%a
echo %nodePath%

the reg query correctly returns

HKEY_LOCAL_MACHINE\software\node.js

InstallPath    REG_SZ    C:\Program Files\nodejs\

but I don't know how to write the 'for' command to grab the file path since it contains a space (C:\Program). I suppose I need to join the 3rd and 4th tokens?

is there a "good" way to write this?

You need only a few modification:

  • change tokens=3 to tokens=2*;
  • read variable %%b rather than %%a;

Here is the fixed code:

set print_nodePath=reg query "hklm\software\node.js" /v InstallPath
for /f "skip=2 tokens=2*" %%a in ('%print_nodePath%') do set "nodePath=%%b"
echo(%nodePath%

This works only if the registry value name does not contain white-spaces on its own.
