Paging in Simple HTML DOM XPATH

Kan iemand mij helpen met de mogelijkheid om in onderstaande script Paging mogelijk te maken?

Ik run de pagina mbv simple html dom. en start op de pagina:
http://www.imdb.com/search/title?year=2016,2016&title_type=feature&sort=moviemeter,asc

De XPATH om naar de volgende pagina te gaan is:
//*[@id="main"]/div/div/div[4]/div/a


<?php
$current_year = date("Y");
//$current_year = "2015";
$movie_title = $row["title"];

//Start xpath scraping
$source = file_get_contents('http://www.imdb.com/search/title?year='.$current_year.','.$current_year.'&title_type=feature&sort=moviemeter,asc';);

$dom = new DOMDocument();

@$dom->loadHTML($source);

$xpath = new DOMXPath($dom);

$rows = $xpath->query("//*[@id=\"main\"]/div/div/div[3]/div/div[3]/h3/a");

foreach($rows as $index => $row){
//echo ($index + 1) . ') ' . $row->textContent . '<br />';
$title_results = $row->textContent;

//preg_replace('/[^A-Za-z0-9\-\']/', '', $title_results);
$title_results_clean = preg_replace('/[^a-zA-Z0-9_ %\[\]\.\(\)%&-]/s', '', $title_results);
//echo $title_results_clean;




//Check if title exist
$query = mysqli_query($connection, "SELECT * FROM video WHERE title='".$title_results_clean."'");

if(mysqli_num_rows($query) > 0){

//echo "title already exists";
}else{
// insert the new item
mysqli_query($connection, "INSERT INTO video (`title`) VALUES ('".$title_results_clean."')");

}



}
