preg_replace regex question

Hi Guys!

I need to create a preg_replace script that will replace the following line from a PHP file.

define("THEME_NAME", "recruiter"); // Theme name

I need to find a regex that will match anything as the appended value of the constant though. For example it should match all of the following:

define("THEME_NAME", ""); // Theme name
define("THEME_NAME", "othertheme"); // Theme name
define("THEME_NAME", "anothertheme12"); // Theme name

Thanks in advance.

What have you tried so far?
