Due to XML's ease of sharing and many other advantages, XML technology is increasingly used in enterprise data processing and other fields, such as Enterprise reports, news releases, and accounting data processing.
XML is quickly becoming a tool for transferring data from the middle layer to the desktop. Because XML data can be integrated with multiple backend (database) sources through the middle layer proxy, most database manufacturers currently fully support XML technology, provides various powerful functions to process XML data.
Microsoft's. NET provides a powerful and fast development tool-C #, which features unprecedented development efficiency, especially in XML programming.
C # provides many related classes to process XML data, such as stream processing classes: XmlReader and XmlWriter; DOM classes: XmlNode, XmlDocument, and XmlElement; Xpath classes: XmlNavigator; XSLT class: XslTransform.
Show XML file content
C # programming is used to display information in XML files. the standard class provided by NET reads XML file content into a StreamReader class object, and then reads XML Information to DataSet using the XmlDataDocument class DataSet to read XML information, dataSet is assigned to a DataGrid on the Web Form in the Form of DataView, and DataBind displays the data. The specific implementation code is as follows:
Using System. Xml;
// The Namespace required for processing XML. You must also add System. XML. Dll in References.
Using System. IO;
// Namespace required for reading XML files
Then add the following code to Page_Load:
Protected void Page_Load (object sender, EventArgs e ){
String datafile = "guest. xml ";
// Assume that the XML file name is guest. xml.
StreamReader tyj = new StreamReader (Server. MapPath (datafile ));
XmlDataDocument datadoc = new XmlDataDocument ();
// Create this object to read XML
Datadoc. DataSet. ReadXml (tyj );
// Read the content of the guest. xml file
DataGrid1.DataSource = datadoc. DataSet. Tables [0]. DefaultView;
