xml追加节点

添加方法

public void XmlAppend(VisitM vm)
{
XmlDocument xmldoc = new XmlDocument();
string path = Server.MapPath("~/Content/VisitFile/VisitFile.xml");
xmldoc.Load(path);

XmlElement node = xmldoc.CreateElement("VisitRecord");
node.SetAttribute("Ip", vm.Ip);
node.SetAttribute("VisitTime", vm.VisitTime);
node.SetAttribute("Word", vm.Word);
//node.SetAttribute("isMobile", vm.isMobile);
node.InnerText=vm.Word;

//将节点加入到指定的节点下
XmlNode xml = xmldoc.DocumentElement.PrependChild(node);
xmldoc.Save(path);
}

protected void Button3_Click(object sender, EventArgs e)
{

//加载xml文档
XmlDocument doc = new XmlDocument();
string path = Server.MapPath("~/Title.xml");
doc.Load(path);
//创建节点
XmlElement xmlElement = doc.CreateElement("Title");

//添加属性
xmlElement.SetAttribute("ID", "21");
xmlElement.SetAttribute("Name","王六");
//将节点加入到指定的节点下
XmlNode xml = doc.DocumentElement.PrependChild(xmlElement);
doc.Save(path);
}

或者是

protected void Button3_Click(object sender, EventArgs e)
{
XmlDocument doc = new XmlDocument();
string path = Server.MapPath("~/Title.xml");
doc.Load(path);
//创建节点
XmlElement xmlElement = doc.CreateElement("Title");
////将节点加入到指定的节点下
XmlNode xmlTitle = doc.DocumentElement.PrependChild(xmlElement);
//为该节点加入属性
XmlAttribute xmlID = doc.CreateAttribute("ID");
xmlID.Value = "22";
xmlTitle.Attributes.Append(xmlID);

XmlAttribute xmlName = doc.CreateAttribute("Name");
xmlName.InnerText = "小三";
xmlTitle.Attributes.Append(xmlName);

doc.Save(path);
}

如果不需要创建节点，直接通过SelectSingleNode(string path)来获取XmlNode，然后再添加属性或者文本节点等，如下：

protected void Button2_Click(object sender, EventArgs e)
{
XmlDocument doc = new XmlDocument();
string path = Server.MapPath("~/XMLFile.xml");
doc.Load(path);
//创建一个book节点
XmlNode xml = doc.SelectSingleNode("//TiTles//TiTle");
XmlAttribute xmlAttribute = doc.CreateAttribute("ss");
xmlAttribute.InnerText = "bb";
xml.Attributes.Append(xmlAttribute);
doc.Save(path);
}
