C#代码:
- XmlDocument xml = new XmlDocument();
- xml.Load(context.Server.MapPath("~/js/XMLFile.xml"));
- XmlNode xn = xml.DocumentElement;
- foreach (XmlNode node in xn.ChildNodes)
- {
- if (node.Name == "info")
- {
- node["content"].InnerText = content;
- node["speed"].InnerText = speed;
- node["color"].InnerText = color;
- }
- }
- xml.Save(context.Server.MapPath("~/js/XMLFile.xml"));
另外两种办法:
XmlDocument doc = new XmlDocument();
doc.LoadXml("<fsdlconfig userName=\"ss\" password=\"134\"/>");
XmlAttribute att =(XmlAttribute)doc.SelectSingleNode("/fsdlconfig/@userName");
Console.WriteLine(att.Value);
att.Value = "test";
string str = doc.OuterXml;
节点userName的值由原来的"ss",变成了"test",然后用doc.OuterXml保存修改后的xml为字符串。
另一种方式:
XmlDocument doc = new XmlDocument();
doc.LoadXml("<fsdlconfig userName=\"ss\" password=\"134\"/>");
XmlElement att = (XmlElement)doc.FirstChild; att.SetAttribute("userName","test"); string str = doc.OuterXml;
