I have common meta tags like that: <meta id="1" name="keywords" content="some keywords" />

My APP is writen in NodeJs and I need to extract all attributes like that:

[
 id: "1",
 name: "keywords",
 content: "some keywords",
]

I have folowing regex:

var attrsRegex = new RegExp(/\s(.*?)=["'](.*?)["']/gi);
var attrs = attrsRegex.exec('<meta name="author" content="Alza a.s." />');
console.log(attrs);

The code return only the first attribute:

[" id="1"", "id", "1", index: 5, input: "<meta id="1" name="keywords" content="some keywords" />"]

It seems the G flag doesnt work.?

`/g` only advances the RegExp lastIndex, you need to call the `exec()` inside a loop to get all the matches. – Wiktor Stribiżew Sep 27 '16 at 10:58
Sorry, but I don't understand. Can you give me some example? – MakoBuk Sep 27 '16 at 11:16
