Question

I have something like:

function(xml){
$(xml).find('tag').each(function(){
//do something});
}

How can I make it cycle only over the tag elements that have different .text() values?

eg.: I have

    <'tag>Hello<'/tag>
    <'tag>Hello<'/tag>
    <'tag>Bye<'/tag>
    <'tag>Hello<'/tag>

and I want to obtain only: Hello, Bye

JS

var history = {},
    value;
$('div').each(function () {
    value = $(this).text();
    if (history[value] === undefined) {
        alert(value);
        history[value] = true;
    }
});

HTML

<div>Hello</div>
<div>Bye</div>
<div>Foo</div>
<div>Bar</div>
<div>Foo</div>
