Question

I am new to regular expressions. I want to use java’s replaceAll() function to replace any CSS comments in a string.

Basically I want to use regex to search for anything that is surrounded by “/*” and “*/” and replace it with “”.

Answer 1

One example where a simple regular expression fails is:

body { font-family: "/* this is not a comment */"; }

But if you don’t care about these cases, you can simply go with this:

str.replaceAll("/\\*.*?\\*/", "");

The match starts at the first /* it finds and then looks for the next */, with as few characters in between as possible (.*?).
