XML Parsing with PHP using simplexml

Question

I m working with Amazon Marketplace Web Service (Amazon MWS) to fetch products.

I need to get the title of the first product :

For the ASIN, I can get it using :

$xml->ListMatchingProductsResult->Products->Product[0]->Identifiers->MarketplaceASIN->ASIN

but for the title, I dont konw how because of the "ns2".

here is the XML data :

<?xml version="1.0"?>
<ListMatchingProductsResponse xmlns="http://mws.amazonservices.com/schema/Products/2011-10-01">
  <ListMatchingProductsResult>
    <Products>
      <Product>
        <Identifiers>
          <MarketplaceASIN>
            <MarketplaceId>A2EUQ1WTGCTBG2</MarketplaceId>
            <ASIN>B01MYV7W6A</ASIN>
          </MarketplaceASIN>
        </Identifiers>
        <AttributeSets>
          <ns2:ItemAttributes xmlns:ns2="http://mws.amazonservices.com/schema/Products/2011-10-01/default.xsd" xml:lang="en-CA">

Thank you in advance.

Here is the solution I found :

$ItemAttributes = $xml->ListMatchingProductsResult->Products->Product[$i]->AttributeSets->ItemAttributes;
$ItemAttributes->registerXPathNamespace('ns2', 'http://mws.amazonservices.com/schema/Products/2011-10-01/default.xsd');
$titles = $ItemAttributes->xpath("//ns2:Title");  // <= this is array
