PHP/DOMXpath/DOMDocument - Unable to parse specific links - php

Question

Here is my code, you can copy and paste it to start runing, it's complete for test:
<?php
$url = "http://www.sportsdirect.com/ladies/ladies-underwear";
libxml_use_internal_errors(true);
$doc = new DOMDocument();
$doc->loadHTMLFile($url);
$xpath = new DOMXpath($doc);
$n = $xpath->query('//div[#class="s-producttext-top-wrapper"]');
$l = $xpath->query('//div[#class="s-producttext-top-wrapper"]/a');
$p = $xpath->query('//div[#class="s-largered"]');
$nl = $xpath->query('//a[#class="swipeNextClick NextLink"]');
$NextLink = $nl->item(0)->getAttribute("data-dcp");
$item = 0;
foreach ($n as $entry) {
$Name = $entry->nodeValue;
$Link = $l->item($item)->getAttribute("href");
$Price = $p->item($item)->nodeValue;
$Find = array('£');
$Replace = array('');
$Price = str_replace($Find, $Replace, $Price);
echo "Name: $Name - Link: $Link - Price: $Price - $NextLink<br>";
$item++;
}
?>
This is parsing all the products from http://www.sportsdirect.com/ladies/ladies-underwear which are on the FIRST page.
Here is the link for the second page http://www.sportsdirect.com/ladies/ladies-underwear#dcp=2&dppp=100&OrderBy=rank
And when i execute this code to get all the products from the SECOND page:
<?php
$url = "http://www.sportsdirect.com/ladies/ladies-underwear#dcp=2&dppp=100&OrderBy=rank";
libxml_use_internal_errors(true);
$doc = new DOMDocument();
$doc->loadHTMLFile($url);
$xpath = new DOMXpath($doc);
$n = $xpath->query('//div[#class="s-producttext-top-wrapper"]');
$l = $xpath->query('//div[#class="s-producttext-top-wrapper"]/a');
$p = $xpath->query('//div[#class="s-largered"]');
$nl = $xpath->query('//a[#class="swipeNextClick NextLink"]');
$NextLink = $nl->item(0)->getAttribute("data-dcp");
$item = 0;
foreach ($n as $entry) {
$Name = $entry->nodeValue;
$Link = $l->item($item)->getAttribute("href");
$Price = $p->item($item)->nodeValue;
$Find = array('£');
$Replace = array('');
$Price = str_replace($Find, $Replace, $Price);
echo "Name: $Name - Link: $Link - Price: $Price - $NextLink<br>";
$item++;
}
?>
I still get the results for the products of the FIRST page. Why?
How can i parse all the products from Page 2, where is my mistake?
Can you please help me out?
Thanks in advance!
