Asp.net|xml| News system Here I use XML instead of data, write a news release system, I hope to be able to play a role, so that more people can understand these latest technology. Here are a few of these files.
Contents.xml
<?xml version= "1.0" encoding= "GB2312"?>
<topiclist type= "Aspcool News" >
<topic>
<title>aspcool news!</title>
</topic>
<topic>
<title>resolve a problem</title>
</topic>
</topiclist>
This is a very simple XML file that is used to display a list of news.
Hello.xml
<?xml version= "1.0" encoding= "GB2312"?>
<document>
<title>aspcool news!</title>
<abstract>test news</abstract>
<author>feiying</author>
<content>
<paragraph>the Firet test</paragraph>
</content>
</document>
This file is used to display the content of the news, the meaning of each of the people to see it, I will not be here to say more.
Here is a list of the pages shown in the news listing.
News.aspx
<%@ Import namespace= "System"%>
<%@ Page language= "C #" debug= "true" codepage= "936"%>
<%@ Import namespace= "System.IO"%>
<%@ Assembly name= "System.Xml"%>
<%@ Import namespace= "System.Xml"%>
<%@ Import namespace= "SYSTEM.XML.XSL"%>
<title>
</title>
<script language= "C #" runat= "Server" >
public string XSLT ()
{
StringWriter writer = new StringWriter ();
Loading XML objects
XmlDocument xmldoc= New XmlDocument ();
XmlDoc. Load (Server.MapPath ("Contents.xml"));
Mount an XSL object
XslTransform Xsldoc = new XslTransform ();
Xsldoc. Load (Server.MapPath ("news.xsl"));
Translating XML into HTML pages
Documentnavigator nav= New Documentnavigator (xmldoc);
Xsldoc. Transform (Nav,null,writer);
return writer. ToString ();
}
</script>
<body>
<%=XSLT ()%>
<p align= "center" >
The program is made by <a href= "www.aspcool.comhttp://www.aspcool.com" >www.aspcool.com</a> design.
</p>
</body>
This page completes the transformation from XML to HTML files through XSLT, and also gives me a further understanding of XSLT.
The following is a page showing the news content:
Main.aspx
<%@ Import namespace= "System"%>
<%@ Page language= "C #" debug= "true" codepage= "936"%>
<%@ Import namespace= "System.IO"%>
<%@ Assembly name= "System.Xml"%>
<%@ Import namespace= "System.Xml"%>
<%@ Import namespace= "SYSTEM.XML.XSL"%>
<title>
</title>
<script language= "C #" runat= "Server" >
public string XSLT ()
{
StringWriter writer = new StringWriter ();
XmlDocument xmldoc= New XmlDocument ();
XmlDoc. Load (Server.MapPath (request["name"] + ". xml"));
XslTransform Xsldoc = new XslTransform ();
Xsldoc. Load (Server.MapPath ("main.xsl"));
Documentnavigator nav= New Documentnavigator (xmldoc);
Xsldoc. Transform (Nav,null,writer);
return writer. ToString ();
}
</script>
<body>
<%=XSLT ()%>
<p align= "Center" > The program was made by <a href= "www.aspcool.comhttp://www.aspcool.com" >www.aspcool.com</a> design. </p>
</body>
This function is the same as above, I will not say more here.
Finally, let's take a look at one of the most responsible pages, the role of which is to create new XML data.
Manage.aspx
<%@ Import namespace= "SYSTEM.XML.XSL"%>
<%@ Import namespace= "System.Xml"%>
<%@ Assembly name= "System.Xml"%>
<%@ Import namespace= "System.IO"%>
<%@ Page language= "C #" debug= "true" codepage= "936"%>
<%@ Import namespace= "System"%>
<HTML>
<HEAD>
<script language= "C #" runat= "Server" >
public void button1_click (object sender, System.EventArgs e)
{
To determine whether a file exists
if (File.exists (Server.MapPath (TextBox1.Text + ". xml"))
{
Response.Write ("FileName already exists," please select the filename.) ");
Response.End ();
}
Else
{
XmlNode Currnode;
XmlDocument xmldoc = new XmlDocument ();
XmlDoc. Load (Server.MapPath ("Contents.xml"));
String insstr= "<topic><title>" +textbox2.text+ </title>Main.aspx?name= "+textbox1.text+" XmlDocumentFragment Docfrag = xmldoc. Createdocumentfragment ();
Docfrag.innerxml = Insstr;
Currnode = xmldoc. DocumentElement;
Currnode.insertafter (Docfrag, currnode.lastchild);
Save the output to a file
XmlDoc. Save (Server.MapPath ("Contents.xml"));
Replace the file in TEXTBOX5 with XML-formatted content.
String XMLFile =textbox5.text.replace ("&", "&");
XMLFile = xmlfile. Replace ("<", "<");
XMLFile = xmlfile. Replace (">", ">");
XMLFile = xmlfile. Replace (@ "" "" "", "" ");
XMLFile = xmlfile. Replace ("" "," "");
XMLFile = xmlfile. Replace ("\ n", "</paragraph><paragraph>");
Writes the data to the newly created XML file.
XmlDocument doc = new XmlDocument ();
Doc. Loadxml ("<?xml version=" 1.0 "encoding=" GB2312 "?>"
<document><title> "+textbox2.text +" </title><abstract> "+
Textbox4.text "</abstract><author>" +textbox3.text+
"</author><content><paragraph>" +xmlfile+ </paragraph>
</content></document> ");
Doc. Save (Server.MapPath (TextBox1.Text + ". xml"));
Response.Write ("You hava input the article!");
Textbox1.text= "";
Textbox2.text= "";
Textbox3.text= "";
Textbox4.text= "";
Textbox5.text= "";
}
Write data to a catalog file
}
