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 </p><p><%@ 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"%> </p><p><html>
<head>
<script language="c#" runat="server"> </p><p>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() ; </p><p>}
else
{ </p><p>xmlnode currnode;
xmldocument xmldoc = new xmldocument();
xmldoc.load(server.mappath("contents.xml")); </p><p>string insstr="<topic><title>"+textbox2.text+"</title><href>main.aspx?name="+textbox1.text+"</href></topic>";
xmldocumentfragment docfrag = xmldoc.createdocumentfragment();
docfrag.innerxml = insstr; </p><p>currnode = xmldoc.documentelement;
currnode.insertafter(docfrag, currnode.lastchild);
//save the output to a file
xmldoc.save (server.mappath("contents.xml")); </p><p>//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="";
