  1. Firstly, you need to remove the paragraph tags that were added by the wp_autop filter. There’s another answer that covers this pretty well: Is there an uw-wp_autop function?

    I’m going to change the function a little for our purposes (based on the markup example you gave):

    function reverse_wpautop( $s ) {
    // Strip newlines
    $s = str_replace( "n", "", $s );

    // Strip all <p> tags
    $s = str_replace( "<p>", "", $s );

    // Replace </p> with a known delimiter
    $s = str_replace( "</p>", "::|::", $s );

    return $s;
}

    If all is working correctly, this should convert your markup from:

    <p>2012-12-12</p>
<p>2012-6-23</p>
<p>2012-7-3</p>

    To:

    2012-12-12::|::2012-6-23::|::2012-7-3::|::

    If you do a split now, you’ll end up with an extra, empty element in your array. So remember to take a substring before you split:

    function split_delimited_string( $s ) {
    // Take a substring, removing the final 5 characters (::|::)
    $s = substr( $s, 0, -5 );

    return explode( "::|::", $s );
}

  2. here is the final working code : 

       //Add a SHORTCODE to get date listing
add_shortcode ('getdate','get_date_listing');
   function get_date_listing ($att) {

    $outputtvar = '';

    // set the default timezone to use. Available since PHP 5.1
    date_default_timezone_set('America/Montreal');

    //ID of the post containing DATE LIST
    $req_id = 901;
    $post = get_page($req_id); 
    $content = apply_filters('the_content', $post->post_content);

    // Strip all <p> tags
    $content = str_replace( "<p>", "", $content );

    // Replace </p> with a known delimiter
    $content = str_replace( "</p>", "|", $content );

    //Separate de dates
    $contentarray = explode( '|', $content );

    //remove the last empty date
    unset($contentarray[count($contentarray)-1]);

    if (qtrans_getLanguage() == 'fr') { setlocale(LC_ALL, 'fr_CA'); $datesetting = "%A, %e %B, %G"; } 
    if (qtrans_getLanguage() == 'en') { setlocale(LC_ALL, 'en_US'); $datesetting = "%A, %B %e, %G";} 

    //prepare the outputt
    $outputtvar .= '<ul>';

    foreach ($contentarray as $key => $value) {
        $timestamp = strtotime($value);
        $localdate = strftime($datesetting,$timestamp);
        $localdate = utf8_encode($localdate);
        $outputtvar .= '<li>' . $localdate . '</li>';
    }

    $outputtvar .= '</ul>';

    return $outputtvar ;

   }
