[我也写点技术]
之前写过一片类似的文章，被R2仁兄指点了一番，发现里面有问题，所以就重新整理了一个，并调试通过，这个网上类似的也很多，只是自己想整理一下，以后就不用再找了。
1. 公告栏(新闻列表)
newslist.xml
＜?xml version="1.0" encoding="GB2312"?＞
＜topiclist type="AspCool News"＞
＜topic＞
＜title＞第一条新闻＜/title＞
＜href＞main.aspx?name=news1＜/href＞
＜/topic＞
＜topic＞
＜title＞第二条新闻＜/title＞
＜href＞main.aspx?name=new2＜/href＞
＜/topic＞
＜/topiclist＞
shownewslist.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("newslist.xml"));
//装入xsl对象
XslTransform xsldoc = new XslTransform();
xsldoc.Load(Server.MapPath("newslist.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()%＞
＜/body＞＜/html＞
2. 每条新闻的显示同理
3.怎么样新建一条新闻
news1.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＞
新建news1.xml的方法
private void btnGetXml_Click(object sender, System.EventArgs e)
{
stirng filename=this.txtfilename.Test;
string title=this.txttitle.Text;
string abstract=this.txtabstract.Text;
string author=this.txtauthor.Text;
string content=this.txtcontent.Text;
//判断文件是否存在
if(File.Exists(Server.MapPath(filename+".xml")))
{
Response.Write("文件名已经存在，请重选文件名。");
Response.End() ;
}
else
{
//create news1.xml
System.Xml.XmlTextWriter myWriter=new XmlTextWriter(filename+".xml",null);
myWriter.WriteProcessingInstruction("xml","version='1.0'");
myWriter.WriteStartElement("content");
myWriter.WriteAttributeString("type","whitePaper");
//
myWriter.WriteStartElement("document");
myWriter.WriteElementString("title",title);
myWriter.WriteElementString("abstract",abstract);
myWriter.WriteElementString("author",author);
myWriter.WriteElementString("content",content);
//
myWriter.WriteEndElement();
myWriter.Flush();
myWriter.Close();
}
}
4.怎么样修改现有的newslist.xml
每增加一条新闻，就要在newslist.xml里加上一条
private void Updatenewslist(string title,string href)
{
//add new nodes to newslist.xml
XmlDocument myDocument=new XmlDocument();
myDocument.Load("newslist.xml");
XmlElement topiclist=(XmlElement)myDocument.GetElementsByTagName("topiclist");
XmlElement topic=myDocument.CreateElement("topic");
XmlElement title= topic.CreateElement("title");
title.InnerText=title;
topic.AppendChild(title);
xmlElement href=topic.CreateElement("href");
href.InnerText=href;
topic.AppendChild(href);
topiclist.PrependChild(topic);
myDocument.Save("newslist.xml");
}
