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 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>
