Hello everyone, I am trying to fetch xml file using jquery.post() method. My code is :

function getTitle()
            {
                jQuery.ajax({
                    type: "GET",
                    url: "https://spreadsheets.google.com/feeds/spreadsheets/private/full.txt",
                    dataType: "xml",
                    success: function(xml) {
                        var i=0;
                        $(xml).find('entry').each(function(){
                            if($(this).find('title').text().toString() == "Sample Spreadsheet"){
                                var href = $(this).find('link')[1].getAttribute('href').toString();
                                var url="https://spreadsheets.google.com/feeds/worksheets/" + href.split('=')[1] + "/private/full";
                                alert(href.split('=')[1]);
                            }
                            i++;
                        });
                    }
                });
            }

But, it is not giving me alert ! How do I solve ?
