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="www.aspcool.comhttp://www.aspcool.com"＞www.aspcool.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="www.aspcool.comhttp://www.aspcool.com"＞www.aspcool.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 filexmldoc.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 ("
","＜/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; LEFT: 230px; POSITION:absolute; TOP: 27px" runat="server" Height="28px" Width="156px"＞asp酷技术资讯网网站内容发布系统＜/asp:label＞＜asp:label id=Label2 style="Z-INDEX: 101; LEFT: 110px; POSITION:absolute; TOP: 68px" runat="server" Height="25px" Width="65px"＞文件名：＜/asp:label＞＜asp:textbox id=TextBox1 style="Z-INDEX: 102; LEFT: 255px; POSITION:absolute; TOP: 64px" runat="server" Height="33px" Width="178px" ＞＜/asp:textbox＞＜asp:label id=Label3 style="Z-INDEX: 103; LEFT: 108px; POSITION:absolute; TOP: 126px" runat="server" Height="36px" Width="86px"＞文章名称：＜/asp:label＞＜asp:textbox id=TextBox2 style="Z-INDEX: 104; LEFT: 256px; POSITION:absolute; TOP: 114px" runat="server" Height="37px" Width="177px"＞＜/asp:textbox＞＜asp:label id=Label4 style="Z-INDEX: 105; LEFT: 114px; POSITION:absolute; TOP: 183px" runat="server" Height="31px" Width="89px"＞作者：＜/asp:label＞＜asp:textbox id=TextBox3 style="Z-INDEX: 106; LEFT: 256px; POSITION:absolute; TOP: 183px" runat="server" Height="36px" Width="179px"＞＜/asp:textbox＞＜asp:label id=Label5 style="Z-INDEX: 107; LEFT: 114px; POSITION:absolute; TOP: 241px" runat="server" Height="51px" Width="81px"＞摘要：＜/asp:label＞＜asp:textbox id=TextBox4 style="Z-INDEX: 108; LEFT: 256px; POSITION:absolute; TOP: 245px" runat="server" Height="36px" Width="179px"＞＜/asp:textbox＞＜asp:label id=Label6 style="Z-INDEX: 109; LEFT: 116px; POSITION:absolute; TOP: 315px" runat="server" Height="36px" Width="78px"＞内容：＜/asp:label＞＜asp:textbox id=TextBox5 style="Z-INDEX: 110; LEFT: 259px; POSITION:absolute; TOP: 303px" runat="server" Height="95px" Width="252px"textmode="MultiLine"＞＜/asp:textbox＞＜/FONT＞＜INPUT id=Button2 style="Z-INDEX: 113; LEFT: 343px; WIDTH: 40px;POSITION: absolute; TOP: 430px; HEIGHT: 24px" type=button value=重置name=Button2 runat="server" OnServerClick="Button2_Click" DESIGNTIMEDRAGDROP="59"＞＜br＞＜br＞＜div id=mess runat=server＞＜/div＞＜br＞＜input type="button" value="提交" OnServerClick="Button1_Click"runat="server" ID="Button1" NAME="Button1" style="Z-INDEX: 112;LEFT: 268px; POSITION: absolute; TOP: 430px"＞＜/form＞＜/body＞＜/HTML＞
此程序在.net beta2 build 9148下测试通过。
