[Plugin – Secondary HTML Content] Split the Secondary Content

Hi,

I have been trying to split the Secondary HTML content produced by using this plugin and using this method.

The code used to split the content is below

// split content at the more tag and return an array
function split_content() {
    global $more;
    $more = true;
    $content = preg_split('/<span id="more-\d+"><\/span>/i', the_content('more'));
    for($c = 0, $csize = count($content); $c < $csize; $c++) {
        $content[$c] = apply_filters('the_content', $content[$c]);
    }
    return $content;
}

I have tried using “get_secondary_content” & “the_secondary_content” as well as other variations in place of “the_content(‘more’)”

Is it possible to split the output of Secondary HTML content?
Any help appreciated, thanks.
