通过AJAX的JS、JQuery两种方式解析XML

$.ajax({

			type : "post",
			data : params,
			success : function(xml) {
				hide();
				if(xml == ""){

				}else{
            		var myTable=document.getElementById( "t_product" );
            		//遍历"ORDER"节点
					$(xml).find('ORDER').each(function(){
            			var id = $(this).find("ORDERID").text();
            			var status = $(this).find("STATUS").text();
            			
            			if(status == "1"){
            				status="未确认";
            			}else{
            				status="已确认";
            			}

			error : function() {
