正则表达式在C代码中提取字符串（不在注释中）

Question

I have this code in C but I only know how to extract string with regular expression that not inside comment code:

1. /*  * "path_build()" function in "home.c" for more information.  
2. * this is an example basic"
3. */
4.
5. /*** Free ***/ 
6. VALOR = string_make(format("%sxtra", libpath)); 
7. event_signal_string(EVENT_INITSTATUS, "Inicializando...");

should only return:

"%sxtra" 
"Inicializando..."

I try:

".*"

but its don't work, it show me all text inside "", including the strings that inside /*...*/

I use EditPag Pro, RegExp panel. It's a game translation project, I take the string of every C file and I translate to Spanish. I can't remove the comments of the original file.

The only thing I have clear is that this is the regex to find comments in C, maybe that will help the solution:

(/\*([^*]|[\r\n]|(\*+([^*/]|[\r\n])))*\*+/)|(//.*)

Any help?

Edit: I put number of lines.

Answer 1

Hernaldo, this is an interesting question.

Here are two versions because I am not sure if you want to capture the " inside of the string " or "the whole string"

The regexps below capture the strings to capture Group 1. You completely ignore the overall match (Group 0) and just focus on Group 1. To retrieve the strings, just iterate over Group 1 matches in your language (discarding empty strings if any).

Version 1: " The inside of the string "

(?s)/\*.*?\*/|"([^"]+)"

This will capture %sxtra and Inicializando... to Group 1.

Version 2: "The whole string"

(?s)/\*.*?\*/|("[^"]+")

This will capture "%sxtra" and "Inicializando..." to Group 1.

Please let me know if you have any questions!

Note: I did not handle /* nested /* comments */ */ as that was not specified in the question. That would require a bit of tweaking and probably a regex engine supporting recursion.

The final solution for EditPad 6/7 is:

(?<!^[ \t]*/?[*#][^"\n]*")(?<=^[^"\n]*")[^"]+
