Question

If I am parsing an xml file with something like :

 $.ajax({
    type: "GET",
    url: "file.xml",
    dataType: "xml",
    success:   function  parseXml(data)
    {
      $(data).find("ITEM").each(function()
        {
            var quant=$("QTY", this).text();
        };
     };
});

How would I sum the total of everything that is returned in QTY?

Get it, add it. Optimized for efficiency using context.

$.get(
    "xml.xml",
    {},
    function( data )
    {
        var total = 0;

        $( "ITEM > QTY", data ).each(
            function()
            {
                var num = parseInt( $(this).text() );

                if( !isNaN(num) )
                    total += num;
            }
        );
    },
    "xml"
);
