不要添加重复的节点 [英] don't add a duplicate node

问题描述

大家好，


我有一个xml文件，其父节点是通过单击按钮时的textbox.text创建的.如果textbox.text再次包含已作为xml文件的父节点包含的文本.它会在标签上显示错误，在运行时可见性为假.

此处" m提供了一些代码，以供您在xml中输入现有标签时显示一些错误

Hi,

here ''m providing some code to display some error while you entered existing tag in xml

protected void Button1_Click(object sender, EventArgs e)
{
    XmlDocument xmldoc = new XmlDocument();
    xmldoc.Load(Server.MapPath ("~/SomeFiles/XMLFile2.xml"));
    XmlNodeList xmlnodli = xmldoc.GetElementsByTagName(TextBox1.Text);
    if (xmlnodli.Count > 0)
    {
        Label1.Text = "your enter tag is already exists";
        Label1.Visible = true;
    }
}

希望这段代码对您有所帮助.

一切顺利
