這裡我就用xml代替資料,寫一個新聞發布系統,希望能夠起到拋磚引玉的作用,使更多的人能夠瞭解這些最新的技術。下面介紹這幾個檔案。 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> 這是一個很簡單的xml檔案,它的作用是用來顯示新聞的列表。 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> 這個檔案是用來顯示新聞的內容,其中各個意思大家一看就明白,我就不在這兒多說了。 下面給大家看新聞列表顯示的頁面。 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(); //裝入xml對象 XmlDocument xmldoc= new XmlDocument(); xmldoc.Load(Server.MapPath("Contents.xml")); //裝入xsl對象 XslTransform xsldoc = new XslTransform(); xsldoc.Load(Server.MapPath("news.xsl")); //把xml轉化成html頁面 DocumentNavigator nav= new DocumentNavigator(xmldoc); xsldoc.Transform(nav,null,writer); return writer.ToString(); } </script> </head> <body> <%=xslt()%> <p align="center"> 該程式由<a href="www.aspcool.comhttp://www.aspcool.com">www.aspcool.com</a>設計製作. </p> </body> </html> 這個頁面完成了從xml通過xslt轉化成html檔案,也使我對於xslt有了進一步的認識。 下面是新聞內容顯示的頁面: 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">該程式由<a href="www.aspcool.comhttp://www.aspcool.com">www.aspcool.com</a>設計製作.</p> </body> </html> 這個功能和上面的一樣,我在這兒就不多說了。 最後,大家來看一下最負責的一個頁面,這個頁面的作用就是用來建立新的xml資料。 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) { //判斷檔案是否存在 if(File.Exists(Server.MapPath(TextBox1.Text +".xml"))) { Response.Write("檔案名稱已經存在,請重選檔案名稱。"); 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中的檔案換成符合xml格式的內容。 string xmlfile =TextBox5.Text.Replace("&","&"); xmlfile = xmlfile.Replace("<","<"); xmlfile = xmlfile.Replace(">",">"); xmlfile = xmlfile.Replace( @"""""","""); xmlfile = xmlfile.Replace(""","'"); xmlfile = xmlfile.Replace ("\n","</paragraph><paragraph>"); //把資料寫入建立的xml檔案中去。 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=""; } //向目錄檔案中寫資料 } 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=宋體> <asp:label id=Label1 style="Z-INDEX: 100;
