{
Stirng filename=this.txt filename. test;
String titlepolicthis.txt title. text;
String abstract=this.txt abstract. text;
String Authorizer this.txt author. text;
String content+this.txt content. text;
// Determine whether a file exists
If (file. exists (server. mappath (filename + ". xml ")))
{
Response. Write ("the file name already exists. Please reselect the file name. ");
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 );

}
4. How to modify the existing newslist. xml
Each time a piece of news is added, add the previous one to newslist. xml.
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 ");
}
