how to escape xml entities in javascript?

Question

In JavaScript (server side nodejs) I\'m writing a program which generates xml as output.

I am building the xml by concatenating a string:

str += \'&l         


        

Answer 1

This might be a bit more efficient with the same outcome:

function escapeXml(unsafe) {
    return unsafe.replace(/[<>&'"]/g, function (c) {
        switch (c) {
            case '<': return '&lt;';
            case '>': return '&gt;';
            case '&': return '&amp;';
            case '\'': return '&apos;';
            case '"': return '&quot;';
        }
    });
}

Answer 2

This is simple:

sText = ("" + sText).split("<").join("&lt;").split(">").join("&gt;").split('"').join("&#34;").split("'").join("&#39;");

Answer 3

maybe you can try this,

function encodeXML(s) {
  const dom = document.createElement('div')
  dom.textContent = s
  return dom.innerHTML
}

If you have jQuery, here's a simple solution:

  String.prototype.htmlEscape = function() {
    return $('<div/>').text(this.toString()).html();
  };

Use it like this:

"<foo&bar>".htmlEscape(); -> "<foo&bar&gt"
