Items Found

Note how the <openSearch:totalResults> XML element requires parsing, by escaping the colon with a double backslash.

        function loadData()
        {                        
            $("#results").empty();
            
            $.get("FeedServer.ashx?url=http://gdata.youtube.com/feeds/api/videos?q=" + 
            $("#txtFindVideo").val() + "&orderby=published&start-index=1&max-results=10&v=2",
                function(data) {
                    var count = $(data).find("openSearch\\:totalResults").text();                    
                    
                    $("#results").append(
                    "<div style=\"margin-top:10px;font-weight:700;font-size:0.8em;\">Total Results: " + 
                    count.toString() + "</div>");
                    
                    $(data).find("entry").each(function() {
                        var html = "<div style=\"margin-top:10px;\">";
                        html += "<h3>" + $(this).find("title").text() + "</h3>";

The server-side code to retrieve the XML data. Note that this is the same generic handler used in the jQuery RSS Demo since it's a generic "proxy" handler for any external site's XML data feed, including RSS:
