Notepad++, replace with regular expression and maintain some variable letters

Example, I have a file that contains many many of the next:

"xxxxxx".toLowerCase()

xxxxxx - some text with variable length.

I want to replace it with:

castlowercase("xxxxxx")

I don't find how to make a regular expression. It's better to take everything between ( ) cause there may be some variable, not just a string...

• Ctrl+H
• Find what: ("[^"]+")\.toLowerCase\(\)
• Replace with: castlowercase\($1\)
• check Match case
• check Wrap around
• check Regular expression
• Replace all

Explanation:

( # start group 1 " # a quote [^"]+ # 1 or more any character that is not a quote " # a quote
) # end group 1
\. # a dot
toLowerCase\(\) # literally toLowerCase()

Replacement:

castlowercase # literally
\( # openning parenthesis, must be escaped in Notepad++
$1 # content of group 1 (i.e. "xxxxxxx")
\) # closing parenthesis, must be escaped in Notepad++

Result for given example:

castlowercase("xxxxxx")

Notepad can't do regular expressions. It is a very basic editor.
So you are asking the impossible.
