This article mainly explains how ASP.net handles XML data. Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "how ASP.net handles XML data".

XML is an extensible markup language, which is more flexible than html mentioned earlier. Although it is only one letter different from HTML, it is very different.

XML is also a markup language, so every tag has to be closed, and it doesn't matter if HTML forgets to close occasionally (it's not recommended that you leave it out here, good writing rules are still necessary).

Secondly, XML as a kind of plain text, its main function is not to display directly on the web page, but as a tool for data storage or data transmission. When it comes to data, XML is very important, some data can not be used to SQL,ORACEL, try not to use large databases, then XML is very necessary.

The following example involves reading and displaying XML by ASP.NET, which you can take a look at.

There is nothing to say about the syntax and specification of XML. Here is an example of how ASP.net manipulates XML:

Special attention? There can be no space between and xml, otherwise the operation will go wrong!

The copy code is as follows:

/ / Save as course.xml

one

Tom Cruise

Mission impossible.mp3

two

Leonardo DiCaprio

My heart will go on.mp3

DataSet provides methods for processing XML documents: ReadXML reads documents, WriteXML writes documents, and so on.

Objective: to read the contents of XML documents into DataSet and display them with GridView. (pay attention to importing System.Data, System.Data.OleDb namespaces)

The copy code is as follows:

Protected void Page_Load (object sender,EventArgs e)

{

DataSet DS = new DataSet (); / / create DataSet object

DS.ReadXML (Server.MapPath ("course.xml")); / / read the XML document

GridView1.DataSource = DS.Tables [0] .DefaultView

GridView1.DataBind ()

}

At this point, I believe you have a deeper understanding of "how ASP.net deals with XML data". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
