一个面试题(机试),关于XML的AJAX的读取与删除

一个XML文件,名称就暂定为GroupStudents.xml吧,内容如下:

<?xml version="1.0" encoding="utf-8"?>
<GroupStutents>
  <GroupStutent value="个人资料">
    <Item>

要求做成下面的样子,不能在网络上查资料~看看自己的动手能力

要求使用jquery,ajax读取XML并能删除(ajax)数据.并保存XML.

删除后台保存可以用到后台代码.

亲们,动手吧..看你能多久搞定

最后,贴上自己写的代码吧.

<form id="form1" runat="server">
    <div>
        <table id='tabList' cellpadding="0" border="1" cellspacing="0" style="border-collapse: collapse">
            <thead>
                <tr>
                    <th>
                        Name
                    </th>
                    <th>
                        FROM
                    </th>
                    <th>
                        TO

后台删除:

                        //GroupStutents/GroupStutent/Item[@ID='" + Request["id"] + "'] 表示属性,没有@表示节点
                        XmlNodeList nodeList = xmlDoc.DocumentElement.SelectNodes("/GroupStutents/GroupStutent/Item[ID='" + Request["id"] + "']");
                        if (nodeList.Count > 0)

                            {
                                node.ParentNode.RemoveChild(node);
                            }
                            xmlDoc.Save(Server.MapPath("/XML/GroupStudents.xml"));
