StringRegExpReplace question in a complex structure?

[youtuber]

Left and right part I want to not delete

Left : "asdf":{"asdf_blabla":"

Right : ","asdf_blabla"

$s = '"asdf":{"asdf_blabla":"The part I want to replace","asdf_blabla"'

Msgbox(0,"", StringRegExpReplace($s, '"asdf":{"asdf_blabla":"(.*?)","asdf_blabla"', 'add something to the part you want to change'))

Just use groups and backreferences

Msgbox(0,"", StringRegExpReplace($s, '("asdf":{"asdf_blabla":")(.*?)(","asdf_blabla")', '$1add something to the part you want to change$3'))

@mikell Now I understand better  $1 $2 $3 👍 Thank you

Also I would like to add it from a variable but removing slash marks cause?

$aDir = @ScriptDir & "\myfolder"
$s = '"asdf":{"asdf_blabla":"The part I want to replace","asdf_blabla"'
ConsoleWrite(StringRegExpReplace($s, '("asdf":{"asdf_blabla":")(.*?)(","asdf_blabla")', '$1' & $aDir & '$3') & @CRLF)

"asdf":{"asdf_blabla":"C:UsersUSERDesktopmyfolder","asdf_blabla"

Yes, backslashes need to be escaped

$aDir = @ScriptDir & "\myfolder"
$aDir = StringReplace($aDir, "\", "\\")
$s = '"asdf":{"asdf_blabla":"The part I want to replace","asdf_blabla"'
ConsoleWrite(StringRegExpReplace($s, '("asdf":{"asdf_blabla":")(.*?)(","asdf_blabla")', '$1' & $aDir & '$3') & @CRLF)
