I am trying to parse xml file from amazon but found difficulties. I am using simplexml_load_string

$xml = simplexml_load_string( 'My xml here' );

but when I do

echo $xml->GetMatchingProductResult->Product->AttributeSets;

it shows nothing

How can I access the Brand value?

My xml file:

<?xml version="1.0"?>
<GetMatchingProductResponse xmlns="http://mws.amazonservices.com/schema/Products/2011-10-01">
<GetMatchingProductResult ASIN="B003IOSNNQ" status="Success">

I know this is an old question but I had a hard time with the same thing.

First simplexml_load_string doesn't handle the namespaces thrown in like this, so you could go recursively and check and then load the namespaces, evaluate the xml and waste a lot of time ...

In my case I didn't care about evaluating the format of the xml with the namespaces, so I just removed them from the string with regex. After this simplexml_load_string won't omit those parts anymore and it's easy to get an array out of it with json_encode and json_decode.

//convert an xml string into an array
function xml2array($xml){
    $xml = preg_replace('/(<\/?)\w+:([^>]*>)/', '$1$2', $xml); //get rid of namespaces
    $xml = simplexml_load_string($xml);
    return json_decode(json_encode($xml),true); //use built-in stuff
}

The only problem with this is when the xml is full of attributes containing useful data, then you would need something else instead of simplexml_load_string. Note that it returns an @attributes element from this:

<GetMatchingProductResult ASIN="B003IOSNNQ" status="Success">

but omits it from this part:

<Width Units="pixels">75</Width>

I have no idea why or how deep down it would check in the nested tags.

echo $xmlobj->children('',true)->ListMatchingProductsResult->Products->Product->AttributeSets->children('ns2',true)->ItemAttributes->Brand.PHP_EOL;
