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

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

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