You basically need to get your string, via str = $(‘#myelement’).html(), then run the function below, which splits the string by line break, strips non-unique elements, then joins it together again:

function uniquediv(str) {
    this.input = str.split("<br>\n");
    this.output = [];
    this.output.contains = function (value) {
        for (this.j in this) {
            if (this[this.j] == value)
                return true;
        }
        return false;
    }
    for (this.i in this.input) {
        if (!this.output.contains(this.input[i]))
            this.output.push(this.input[i]);
    }
    return this.output.join("<br>\n");
}
