ı can't get match string with regex in nodejs : I have a string like this :  <ns2:NewsPaper unitid="112234"> . I need just this part : unitid="112234" . I write a piece of code. But it returns null. Here is my code :

    var value = "<ns2:NewsPaper unitid="112234">";
    let abc = /NewsPaper>(\*)</.exec(value);
            console.log(abc);

It returns null. Why ?
