从文本框输入接收输入-解网

问：

我需要从文本框接收输入，以便使用新文本更新我的 xml 文件。

我有这个代码脚本：

<script runat="server">
    protected void btnSave_Click(object sender, EventArgs e)
    {
        string xmlPath = MapPath("xml/feed.xml");
        XmlDocument doc = new XmlDocument();

        //Check if the file already exists or not
        if (System.IO.File.Exists(xmlPath))
        {
            string Path2xml = MapPath("xml/feed.xml");
            XDocument xdoc = XDocument.Load(Path2xml);

            string txt2Title = txtTitle.Text;
            //xdoc.Element("CGTemplateDATA").Element("title").SetValue(txt2Title);
            // or even better option
            xdoc.Descendants("title").FirstOrDefault().SetValue(txt2Title);

            xdoc.Save(Path2xml);

            lblResult.Text = "XML dokumentet er blevet opdateret";
        }
        else
        {            
            XmlNode declarationNode = doc.CreateXmlDeclaration("1.0", "utf-8", "yes");
            doc.AppendChild(declarationNode);
            XmlNode bookNode = CreateBookNode(doc);                        
            //Append the cgtemplatedata node to the document
            doc.AppendChild(bookNode);
            lblResult.Text = "XML dokumentet er hermed oprettet";
            doc.Save(xmlPath);
        }
    }

    XmlNode CreateBookNode(XmlDocument doc)
    {
        XmlNode bookNode = doc.CreateElement("CGTemplateDATA");
        //Add all the children of the book node            
        XmlNode titleNode = doc.CreateElement("title");
        titleNode.InnerText = txtTitle.Text;
        bookNode.AppendChild(titleNode);

        XmlNode textNode = doc.CreateElement("text");
        textNode.InnerText = txtText.Text;
        bookNode.AppendChild(textNode);

        XmlNode referenceNode = doc.CreateElement("reference");
        referenceNode.InnerText = txtReference.Text;
        bookNode.AppendChild(referenceNode);

        return bookNode;
    }
</script>

它不对标题中的文本做任何事情，也不像我检查文本框中的文本那样：

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<CGTemplateDATA>
  <title>Title</title>
  <text>put text here</text>
  <reference>put ref here</reference>
</CGTemplateDATA>

没有显示错误，但它没有更新我的字符串？

这是我的网络：

            </tr>
        </table>

我无法弄清楚，但答案可能就在我面前？
