This article will explain in detail the sample analysis of the basic operation of XML documents. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

1. Brief introduction

Using System.Xml;// initializes a xml instance XmlDocument xml=new XmlDocument (); / / imports the specified xml file xml.Load (path); xml.Load (HttpContext.Current.Server.MapPath ("~ / file/bookstore.xml")); / / specifies a node XmlNode root=xml.SelectSingleNode ("/ root"); / / gets all the direct child nodes under the node XmlNodeList childlist=root.ChildNodes;// to determine whether there is a child node root.HasChildNodes under that node / / get a collection of peer nodes with the same name XmlNodeList nodelist=xml.SelectNodes ("/ Root/News"); / / generate a new node XmlElement node=xml.CreateElement ("News"); / / add a node to the specified node as its child node root.AppendChild (node); / / add the node to a child node under the specified node before root.InsertBefore (node,root.ChildeNodes [I]); / / assign the new attribute of the specified node and assign the value node.SetAttribute ("id", "11111") / / add a child node root.AppendChild (node) for the specified node; / / get the specified attribute value of the specified node string id=node.Attributes ["id"] .Value;// gets the text string content=node.InnerText;// in the specified node to save the XML file string path=Server.MapPath ("~ / file/bookstore.xml"); xml.Save (path); / / or use: xml.Save (HttpContext.Current.Server.MapPath ("~ / file/bookstore.xml"))

How to operate XML in C#.net

Namespaces that need to be added:

Define several public objects: XmlDocument xmldoc; XmlNode xmlnode; XmlElement xmlelem

1. Create a xml file under the server directory with the same name:

Method 1:

Xmldoc = new XmlDocument (); / / add the declarative paragraph of XML, XmlDeclaration xmldecl;xmldecl = xmldoc.CreateXmlDeclaration ("1. 0", "gb2312", null); xmldoc.AppendChild (xmldecl); / / add a root element xmlelem = xmldoc.CreateElement ("", "Employees", ""); xmldoc.AppendChild (xmlelem); / / add another element for
