簡單RSS編程 Only parsing RSS (XML) and displaying its contents

1：Java Rss開源組件包很多，
如RSSLibJ、RSSLib4J、RSS Reader、FaceRSS等等，
本文使用rssutils.jar，Sun網站有提供下載 。
2：用Myeclipse建WebProject,Jar 放入lib中，tld放入WEB-INF下
3：web.xml

<? xml version = "1.0" encoding = "UTF-8" ?>

<! DOCTYPE web-app PUBLIC "-//Sun Microsystems,
Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd" >

< web-app >

< taglib >

< taglib-uri > /WEB-INF/rssutils.tld </ taglib-uri >

< taglib-location > /WEB-INF/rssutils.tld </ taglib-location >

</ taglib >

</ web-app >
4:index .jsp                 
      以CSDN為例，去網站找到Rss xml http://dev.csdn.net/rss/2.xml

<%@ page language = "java" import = "java.util.*"
  pageEncoding = "BIG5" %>

<%@ taglib uri = "/WEB-INF/rssutils.tld"
prefix = "rss" %>

< html >

</ head >

< body >

    < rss:feed url = "http://dev.csdn.net/rss/2.xml"
     feedId = "csdn" />

    < b > Image: </ b >

    < rss:channelImage feedId = "csdn" />

    < br >

    < b > Title: </ b >

    < rss:channelTitle feedId = "csdn" />

    < br >

    < b > Link: </ b >

    < rss:channelLink feedId = "csdn" asLink = "true" />

    < br >

    < b > Description: </ b >

    < rss:channelDescription feedId = "csdn" />

    < br >

    < ul >

        < rss:forEachItem feedId = "csdn" >

            < li >

                < rss:itemDescription feedId = "csdn" />

        </ rss:forEachItem >

    </ ul >

</ body >

</ html >

5：部署、訪問 OK.
