1.在根目录下加入rss.php一个文档，方便全站动态调用.

<?php
require_once (dirname(__FILE__) . "/include/common.inc.php");
require_once DEDEINC."/arc.partview.class.php";
$pv = new PartView();
$pv->SetTemplet($cfg_basedir . $cfg_templets_dir . "/tradefax/dingyue.htm");
header("Content-type:application/xml");
$pv->Display();
?>

2.在模板下加入htm,以便调用.

<?xml version="1.0" encoding="{dede:global.cfg_soft_lang /}" ?>
<rss version="2.0">
<channel>
<title>{dede:global.cfg_webname/}</title>
<link>{dede:global.cfg_basehost/}</link>
<description>{dede:global.cfg_description/}</description>
<language>zh-cn</language>
<generator>{dede:global.cfg_webname/}</generator>
{dede:arclist row='20' col='1' titlelen='100' orderby='pubdate'}
<item>
<title><![CDATA[[field:title function='html2text(@me)'/]]]></title>
<link>[field:arcurl/]</link>
<category>[field:typename/]</category>
<pubDate>[field:pubdate function='strftime("%a, %d %b %Y %H:%M:%S +0800",@me)'/]</pubDate>
<description>
<![CDATA[[field:array runphp='yes']@me = (strpos(@me['litpic'],'defaultpic') ? "" : "<a href='{@me["arcurl"]}'  target='_blank'><img src='{@me["litpic"]}' border='0' /></a>"); [/field:array][field:description function='html2text(@me)'/]]]>
</description>
</item>
{/dede:arclist}
</channel>
</rss>
