其实争论谁好谁坏本身是没有多大意思的,因为.net本身已经和xml紧密的结合在一起了。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 href="http://zzmzaizai.cnblogs.com">zzmzaizai.cnblogs.com</a>设计制作.</p> </body> </html> 这个页面完成了从xml通过xslt转化成html文件,也使我对于xslt有了进一步的认识。 下面是新闻内容显示的页面: 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" %> <html> <head> <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> </head> <body> <%=xslt()%> <p align="center">该程序由<a href="http://zzmzaizai.cnblogs.com">zzmzaizai.cnblogs.com</a>设计制作.</p> </body> </html> 这个功能和上面的一样,我在这儿就不多说了。 最后,大家来看一下最负责的一个页面,这个页面的作用就是用来建立新的xml数据。 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) { //判断文件是否存在 if(File.Exists(Server.MapPath(TextBox1.Text +".xml"))) { Response.Write("文件名已经存在,请重选文件名。"); Response.End() ; } else { XmlNode currNode; XmlDocument xmldoc = new XmlDocument(); xmldoc.Load(Server.MapPath("contents.xml")); string InsStr="<topic><title>"+TextBox2.Text+"</title><href>main.aspx?name="+TextBox1.Text+"</href></topic>"; 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")); //把TextBox5中的文件换成符合xml格式的内容。 string xmlfile =TextBox5.Text.Replace("&","&"); xmlfile = xmlfile.Replace("<","<"); xmlfile = xmlfile.Replace(">",">"); xmlfile = xmlfile.Replace( @"""""","""); xmlfile = xmlfile.Replace("'","'"); xmlfile = xmlfile.Replace ("\n","</paragraph><paragraph>"); //把数据写入新建的xml文件中去。 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=""; } //向目录文件中写数据 } public void Button2_Click(object sender, System.EventArgs e) {} </script> <meta content="Internet Explorer 5.0" name=vs_targetSchema> <meta content="Microsoft Visual Studio 7.0" name=GENERATOR> <meta content=C# name=CODE_LANGUAGE> </HEAD> <body MS_POSITIONING="GridLayout"> <form runat="server"> <FONT face=宋体> <asp:label id=Label1 style="Z-INDEX: 100;
