jQuery和XML：这是最后一个元素吗？

Question

I have grabbed some XML data using this piece of jQuery:

$.ajax({
    type: "POST",
    url: "siteList.xml",
    dataType: "xml",
    success: function(xml) {
        $(xml).find('wrapper').each(function(){
            $(this).find('site').each(function(){
                //check whether this is the last element...
            });
        });
    }
});

What I would like to do is: Check whether I am parsing the last site element from the XML I pulled in.

edit: I cannot (as far as I'm aware), do this:

$(this).find('site').each(function(){
    $(this).last(); //nope
    $(this).find('site').last(); //nope
});

Answer 1

Just use something like this to get the last site:

$(this).find('site').last()

Hope it helps!

Answer 2

Take a look at the ':last' selector or the .last() function. You could do a test to see if the current site is the same as the last one.
