你的代碼工作，以測試它，我創建一個名字TestXml.xml

<?xml version="1.0" encoding="utf-8"?> 
<Data> 

</Data> 

和ASPX代碼

 <asp:Button ID="button" runat="server" Text="Write XML" 
    onclick="button_Click" /> 
<asp:TextBox ID="xmlContent" runat="server" /> 
<asp:TextBox ID="xmlTitle" runat="server" /> 

和按鈕的Click事件代碼

protected void button_Click(object sender, EventArgs e) 
{ 
    XmlDocument xmlfile = new XmlDocument(); 
    xmlfile.Load(Server.MapPath("~/TestXML.xml")); 
    //create element 
    XmlElement theNewsTag = xmlfile.CreateElement("news"); 
    XmlElement theTitleTag = xmlfile.CreateElement("title"); 
    XmlElement theContentsTag = xmlfile.CreateElement("contents"); 
    //create text node 
    XmlText theTitleText = xmlfile.CreateTextNode(xmlTitle.Text); 
    XmlText theContentsText = xmlfile.CreateTextNode(xmlContent.Text); 
    //append 
    theTitleTag.AppendChild(theTitleText); 
    theContentsTag.AppendChild(theContentsText); 

    theNewsTag.AppendChild(theTitleTag); 
    theNewsTag.AppendChild(theContentsTag); 
    //save 
    xmlfile.DocumentElement.AppendChild(theNewsTag); 
    xmlfile.Save(Server.MapPath("~/TestXML.xml")); 


} 

一個xml

我得到了以下輸出

<?xml version="1.0" encoding="utf-8"?> 
<Data> 
    <news> 
    <title>second1</title> 
    <contents>first1</contents> 
</news> 
</Data>
