How do I strip tag from javascript String object using Regex or some better alternative?

Question

Here is code:

   <div class="rightColoumn" id="divreports">
       <link href="/favicon.ico" rel="shortcut icon" type="image/x-icon">
       <link href="../ClientScript/General.css" rel="stylesheet" type="text/css">
    </div>

I wish I could remove lines completely.

javascript String object strObject contains this html.

use HTML/Javascript to remove `link` nodes from DOM. – Braj Aug 21 '14 at 05:28 — Braj, Aug 21 '14 at 05:28

How about just parsing it as what it is, HTML

var strObject = '<div class="rightColoumn" id="divreports"><link href="/favicon.ico" rel="shortcut icon" type="image/x-icon"><link href="../ClientScript/General.css" rel="stylesheet" type="text/css"></div>';

var parser = new DOMParser();
var doc    = parser.parseFromString(strObject, "text/html");
var parent = doc.getElementById('divreports');
var links  = parent.getElementsByTagName('link');

for (var i=links.length; i--;) parent.removeChild(links[i]);

here's another way to remove < link tag lines:

strObject.replace(/^.*<link.*$/mg, "");

It will work if your string has line break '\n' at the end of each line.
