JavaScript multiline string decode

I have a string: 

<Grid><Description>LINE 1
LINE 2
LINE 3
LINE 4
</Description><</Grid>

I need it to be decoded with line breaks. I found solution: 

function decodeString(stringToDecode) {
    if (!stringToDecode) {
        return stringToDecode;
    }
    return $('<div />').html(stringToDecode).text();
}

But it makes single line and replaces all the line breaks with spaces.

function decodeString(stringToDecode) {
    return stringToDecode ? $('<div />').html(stringToDecode.replace(/[\n\r]/g, "<br> \r\n")).text() : ""
}

you may use the following to replace your line breaks with <br /> tags an then set the HTML:

return $('<div />').html(stringToDecode.replace(/\n/, '&lt;br /&gt;')).text();

Your sample has CR/LF - but that is not a line break in HTML. You need to replace it with a valid HTML line break ie the < br > tag.

Your function has a strange if statement that does not make much sense. Why return stringToDecode when you've just proven it is null? Also, $('<div />').html(stringToDecode).text() will not do anything helpful.

Try something like this:

function decodeString(stringToDecode) {
if (!stringToDecode) {
    return "";
}
var regX = /\\n/g;
var replaceString = '<br> \\n';
return stringToDecode.replace(regX, replaceString);
}
