hi joeblow.
It's quite easy to make RSS feeds.
eg) RSS of today's events
create piCal/todays_rss2.php
<?php
include '../../mainfile.php';
if (function_exists('mb_http_output')) {
mb_http_output('pass');
}
header ('Content-Type:text/xml; charset=utf-8');
// for "Duplicatable"
$mydirname = basename( dirname( __FILE__ ) ) ;
if( ! preg_match( '/^(\D+)(\d*)$/' , $mydirname , $regs ) ) echo ( "invalid dirname: " . htmlspecialchars( $mydirname ) ) ;
$mydirnumber = $regs[2] === '' ? '' : intval( $regs[2] ) ;
// 各種パスの設定
$mod_path = XOOPS_ROOT_PATH."/modules/$mydirname" ;
$mod_url = XOOPS_URL."/modules/$mydirname" ;
// piCalクラスの定義
require_once( "$mod_path/class/piCal.php" ) ;
require_once( "$mod_path/class/piCal_xoops.php" ) ;
// オブジェクトの生成
$cal = new piCal_xoops( date( 'Y-n-j' ) , $xoopsConfig['language'] , true ) ;
$cal->use_server_TZ = true ;
// cid による影響を受けないようにする
$cal->now_cid = 0 ;
// 各プロパティの設定
$cal->conn = $xoopsDB->conn ; // 本来はprivateメンバなので将来的にはダメ
include( "$mod_path/include/read_configs.php" ) ;
$cal->base_url = $mod_url ;
$cal->images_url = "$mod_url/images/$skin_folder" ;
$cal->images_path = "$mod_path/images/$skin_folder" ;
$block =& $cal->get_blockarray_date_event( "$mod_url/index.php" ) ;
echo "<?xml version=\"1.0\" encoding=\"UTF-8\" ?>
<rss version=\"2.0\">

foreach( $block['events'] as $event ) {
