用ASP.NET和XML做的新闻系统

2022-07-15 80酷酷网 80kuku.com

　　asp.net|xml|新闻系统这里我就用xml代替数据，写一个新闻发布系统，希望能够起到抛砖引玉的作用，使更多的人能够了解这些最新的技术。下面介绍这几个文件。

contents.xml
<?xml version="1.0" encoding="GB2312"?>
<topiclist type="AspCool News">
<topic>
<title>aspcool news!</title>
<href>main.aspx?name=hello</href>
</topic>
<topic>
<title>Resolve a problem</title>
<href>main.aspx?name=test</href>
</topic>
</topiclist>

　　这是一个很简单的xml文件，它的作用是用来显示新闻的列表。

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>

　　这个文件是用来显示新闻的内容，其中各个意思大家一看就明白，我就不在这儿多说了。

　　下面给大家看新闻列表显示的页面。

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" %>
<html>
<head>
<title>
</title>
<script language="c#" runat="server">
public string xslt()
{
StringWriter writer = new StringWriter();
//装入xml对象
XmlDocument xmldoc= new XmlDocument();
xmldoc.Load(Server.MapPath("Contents.xml"));
//装入xsl对象
XslTransform xsldoc = new XslTransform();
xsldoc.Load(Server.MapPath("news.xsl"));
//把xml转化成html页面
DocumentNavigator nav= new DocumentNavigator(xmldoc);
xsldoc.Transform(nav,null,writer);
return writer.ToString();
}
</script>
</head>
<body>
<%=xslt()%>
<p align="center">

　　该程序由<a language="c#" runat="server">
