利用xsl文件对xml文件倒序排序并显示 （转载）
xml文件是要靠xsl样式文件来显示的，以达到读者正常浏览的目的。有点类似于样式表的意思。
1xml文件Comment.xml
xml version="1.0" encoding="utf-8"?><AllComment> <Comment NewsId="152"> <CommentContent>3333333333CommentContent> <AddTime>2007-5-28 22:41:08AddTime> Comment> <Comment NewsId="153"> <CommentContent>4444CommentContent> <AddTime>2007-5-28 22:41:48AddTime> Comment> <Comment NewsId="154"> <CommentContent>hhhhhhhhhhCommentContent> <AddTime>2007-5-28 22:41:52AddTime> Comment> <Comment NewsId="151"> <CommentContent>fffCommentContent> <AddTime>2007-5-28 22:42:03AddTime> Comment> <Comment NewsId="154"> <CommentContent>bbbbbCommentContent> <AddTime>2007-5-28 23:04:23AddTime> Comment>AllComment>2、xsl文件Comment.xsl
xml version="1.0" encoding="utf-8"?><xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"><xsl:param name="strNewsId"/><xsl:template match="/"> <html> <body> <FONT face="Verdana" size="3"> <TABLE cellspacing="5" cellpadding="1"> <TR bgcolor="#AAAAAA"> <TD class="header"> <B>评论内容B> TD> <TD class="header"> <B>发表时间B> TD> TR> <xsl:for-each select="//AllComment/Comment[@NewsId=$strNewsId]"> <xsl:sort select="AddTime" order="descending" />//倒序排序 <TR bgcolor="#DDDDDD"> <TD> <xsl:value-of select="CommentContent"/> TD> <TD> <xsl:value-of select="AddTime"/> TD> TR> xsl:for-each> TABLE> FONT> <!-- This is an XSLT template file. Fill in this area with the XSL elements which will transform your XML to XHTML. --> body> html>xsl:template>xsl:stylesheet>
3、aspx文件DisplayComment.aspx
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="DisplayComment.aspx.cs" Inherits="NewsFiles_DisplayComment" %>DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml" ><head runat="server"> <title>显示评论title>head><body> <form id="form1" runat="server"> <div> <asp:Xml ID="Xml1" runat="server" DocumentSource="../XmlFiles/Comment.xml" TransformSource="../XmlFiles/Comment.xsl">asp:Xml> div> form>body>html>
4、.aspx.cs文件
using System;using System.Data;using System.Configuration;using System.Collections;using System.Web;using System.Web.Security;using System.Web.UI;using System.Web.UI.WebControls;using System.Web.UI.WebControls.WebParts;using System.Web.UI.HtmlControls;using System.Xml;using System.Xml.Xsl;using System.Xml.XPath;public partial class NewsFiles_DisplayComment : System.Web.UI.Page
...{
protected void Page_Load(object sender, EventArgs e)
...{ string NewsId = Request.QueryString["NewsId"].ToString().Trim(); XPathDocument xmlDoc = new XPathDocument(Server.MapPath("../XmlFiles/Comment.xml")); XslTransform xmlTrans = new XslTransform(); xmlTrans.Load(Server.MapPath("../XmlFiles/Comment.xsl")); XsltArgumentList xsltArgList = new XsltArgumentList(); xsltArgList.AddParam("strNewsId", "", NewsId); Response.ContentType = "text/html"; xmlTrans.Transform(xmlDoc, xsltArgList, Response.OutputStream);
