What is wrong with regular expression?

Question

JavaScript

var re = /<!\-\-[^\-\->]*?\-\->/g;

var str = '..<!-- Мой -- комментарий \n тест -->';

alert( str.match(re) );

I want to get a comment through a regular expression, but the output is null. Where is the mistake?

Answer 1

Too smart.

var re = /<!--[\s\S]*?-->/g;
var str = '..<!-- Мой -- комментарий \n тест -->';
alert( str.match(re) );

Answer 2

document.body.innerHTML.match(/<!--([\s\S]+?)-->/g)
