I want to create a custom rss feed

<?php
/*
Template Name: Custom Feed
*/

function filter_where($where = \'\') {
    //posts in the last 30 days
    $where .= " AND post_date > \'" . date(\'Y-m-d\', strtotime(\'-2 days\')) . "\'";
    return $where;
  }
add_filter(\'posts_where\', \'filter_where\');
    $args=array(
      \'post_type\' => \'post\',
      \'post_status\' => \'publish\',
      \'showposts\' => -1,
      \'caller_get_posts\'=> 1
      );
$my_query=new WP_Query($args);
remove_filter(\'posts_where\', \'filter_where\');
header("Content-Type: application/rss+xml; charset=UTF-8");
echo \'<?xml version="1.0"?>\';
?><rss version="2.0">
<channel>
  <title>Something</title>
  <link>#</link>
  <description>The latest blog posts from #</description>
  <language>en-us</language>
<?
  if( $my_query->have_posts() ) {
    while ($my_query->have_posts()) : $my_query->the_post(); ?>
      <item>
    <title><?php the_title(); ?></title>
    <link><?php the_permalink() ?></link>
  </item>
     <?php
    endwhile;
  } //if ($my_query)?>
</channel>
</rss>
<?PHP wp_reset_query(); //just in case
?>

Now the final code for Custom Rss feed fetch from 48 hours. I can get right results from it.

Thanks for your help.
