请教2个问题。。麻烦大家帮忙解决一下！

Question

问题一：关于操作XML的问题：
写一个上下班的考勤的程序，很简单的。就是每个员工来了后，输入工号和密码并点击上班按钮，这时候程序建立一个以员工工号为文件名的xml文件。然后将上班时间写入xml中，然后下班时候记录下班时间。怎么做才能在页面中，把每天的上下班时间写在一行内，比如上班时间2010-5-29 8：30 下班时间2010-5-29 18：00，XML文件不是太熟，只知道读取节点内容。
我的代码如下：
   XmlDocument xmldoc=new XmlDocument();
            xmldoc.Load("003.xml");
            if (xmldoc != null)
            {
                XmlNode dudu = xmldoc.SelectSingleNode("work");
            }
还是不太懂，应该如何把时间写入到XML文件中来，请给个例子好吗？还有又如何把数据读取出来呢？并添加到listview中，希望给点代码学习一下。问题二：在listiview中选择和textbox1.text相等值的行，并高亮出来。 和用鼠标选择整行，fullrowselect一样的效果就行
           int j = 0;
            for (int i = 0; i < listView1.Items.Count; i++)
            {
                if (textBox1.Text == this.listView1.Items[i].SubItems[0].Text)
                {
                    j = i;
                }
            }
            this.listView1.SelectedIndices.Add(j);
            this.listView1.Items[j].Selected = true;我想把listiview控件中，第一列数值和textbox1.text相等的整行高亮出来。请假如何选择整行？

问题一：
 XmlDocument xmldoc=new XmlDocument();
  xmldoc.Load("003.xml");
  if (xmldoc != null)
  {
  XmlNode dudu = xmldoc.SelectSingleNode("work");
   dudu.InnerText = "2009-01-02";  //赋值
   string s = dudu.InnerText;       //取值
  }
  
   //最后要保存
   xmldoc.Save...
  要是InnerText不好用，看下InnerXml属性，记不大清了
问题二：
 int j = 0;
  for (int i = 0; i < listView1.Items.Count; i++)
  {
  if (textBox1.Text == this.listView1.Items[i].SubItems[0].Text)
  {
      this.listView1.Items[i].Selected = true;
    }
  }

这是以前在学校自己做的小例子。现在没时间帮你整合，你自己看看吧  static void Main(string[] args)
        {
            int k = 0;
            XmlDocument doc = new XmlDocument();

XML 你可以把所有的员工信息都放在一个XML文件里面啊，那样又不麻烦
