jquery对于xml这种数据的处理是内置支持的，这一点没有任何问题。但前提是返回的数据没有带任何命名空间。例如下面这份数据
复制代码 代码如下:
<?xml version="1.0" encoding="utf-8" ?>
<data>
<Employee id="1" firstName="ares" lastName="chen"></Employee>
<Employee id="1" firstName="ares" lastName="chen"></Employee>
<Employee id="1" firstName="ares" lastName="chen"></Employee>
<Employee id="1" firstName="ares" lastName="chen"></Employee>
<Employee id="1" firstName="ares" lastName="chen"></Employee>
<Employee id="1" firstName="ares" lastName="chen"></Employee>
<Employee id="1" firstName="ares" lastName="chen"></Employee>
<Employee id="1" firstName="ares" lastName="chen"></Employee>
</data>
要处理这样的数据，jquery代码大致如下
复制代码 代码如下:
var div = $("#placeholder");
// 处理不带命名空间的xml
$.get("data.xml", null, function (data) {
var employees = $("Employee", data); //找到所有的Employee节点
var ul = $("<ul />");
employees.each(function () {
$("<li />").text($(this).attr("firstName") + " " + $(this).attr("lastName")).appendTo(ul);// 将每一行数据构造一个新的li标签，并且将其插入到ul中
});
ul.appendTo(div);
});
但如果我们的XML数据带有命名空间，则上述代码就会无效。原因是因为jquery默认处理不了命名空间\
复制代码 代码如下:
<?xml version="1.0" encoding="utf-8" ?>
<data xmlns:d="http://tech.xizhang.com">
<d:Employee id="1" firstName="bill" lastName="gates"></d:Employee>
<d:Employee id="1" firstName="bill" lastName="gates"></d:Employee>
<d:Employee id="1" firstName="bill" lastName="gates"></d:Employee>
<d:Employee id="1" firstName="bill" lastName="gates"></d:Employee>
<d:Employee id="1" firstName="bill" lastName="gates"></d:Employee>
<d:Employee id="1" firstName="bill" lastName="gates"></d:Employee>
<d:Employee id="1" firstName="bill" lastName="gates"></d:Employee>
<d:Employee id="1" firstName="bill" lastName="gates"></d:Employee>
<d:Employee id="1" firstName="bill" lastName="gates"></d:Employee>
<d:Employee id="1" firstName="bill" lastName="gates"></d:Employee>
<d:Employee id="1" firstName="bill" lastName="gates"></d:Employee>
<d:Employee id="1" firstName="bill" lastName="gates"></d:Employee>
</data>
为了解决这个问题，有热心的网友，编写了一个jquery插件，叫做jquery.xmlns.js，有兴趣可以通过下面了解和下载
http://";
// 处理带命名空间的xml
$.get("datawithnamespace.xml", null, function (data) {
var employees = $("d|Employee", data); //找到所有的Employee节点
var ul = $("<ul />");
employees.each(function () {
$("<li />").text($(this).attr("firstName") + " " + $(this).attr("lastName")).appendTo(ul);
});
ul.appendTo(div);
});
});
</script>
</head>
<body>
<form id="form1" runat="server">
<div id="placeholder">
</div>
</form>
</body>
</html>
最后，在浏览器中看到的效果如下。有图有真相
