Question

I am trying and trying to parse an XML document. I can get all of the information when I look at a var_dump, but what I need to do is pull out the Id and image url from the document. I have tried using a for each loop, and it will go through the loop the correct number of times, but the Id number that I need never changes.
The XML document is:

<?xml version="1.0"?>
<GetMatchingProductForIdResponse xmlns="http://mws.amazonservices.com/schema/Products/2011-10-01">
<GetMatchingProductForIdResult Id="9781124028491" IdType="ISBN" status="ClientError">
 <Error>
<Type>Sender</Type>
<Code>InvalidParameterValue</Code>
<Message>Invalid ISBN identifier 9781124028491 for marketplace ATVPDKIKX0DER</Message>
</Error>
</GetMatchingProductForIdResult>
<GetMatchingProductForIdResult Id="9780030114687" IdType="ISBN" status="Success">

I have cut it down for brevity.
My php is this:

 foreach($parsed_xml->GetMatchingProductForIdResult as $item ) {
 //$ean =$parsed_xml->GetMatchingProductForIdResult->attributes()->Id; var_dump($ean);//->attributes()->Id
 $current = $parsed_xml->GetMatchingProductForIdResult->Products;

        print_r(" passed the foreach statement ");

 //$status = $parsed_xml->GetMatchingProductForIdResult->attributes()->status;

     //$isbn13 = $ean;print_r($isbn13);
      if(isset($parsed_xml->GetMatchingProductForIdResult, $current, $current->Product, $current->Product->AttributeSets)){
        $amazonResult = array(
                            'isbn' => $parsed_xml->GetMatchingProductForIdResult->attributes()->Id,//$isbn13,
            'ImageURL' => str_replace('SL75','SL200',$current->Product->AttributeSets->children('ns2', true)->ItemAttributes->SmallImage->URL),
                            );
   print_r(" Success was true ");

     }  else {

$amazonResult = array(
                            'isbn' => $parsed_xml->GetMatchingProductForIdResult->attributes()->Id,//$isbn13,
            'ImageURL' => "Jim",
                            );
    print_r(" Success was false ");
}    
    //update image in images table
    print_r(" at the insert statement ");
$conn->query("INSERT INTO images (isbn, image) VALUES ('" . $amazonResult['isbn'] . "', '" . $amazonResult['ImageURL'] . "')");

How do I get each individual Id when going through the loop?

Answer 1

The final solution after much trial and error is:

    $parsed_xml = ProductId_xml($isbn);


  foreach($parsed_xml->GetMatchingProductForIdResult as $item ) {
 $ean =$item->attributes()->Id;
$current = $item->Products;

 $status = $item->attributes()->status;

      if (stristr($status, "Success") == true)
{
        $amazonResult = array(
                            'isbn' => $ean,//$parsed_xml->GetMatchingProductForIdResult->attributes()->Id,
            'ImageURL' => str_replace('SL75','SL200',$current->Product->AttributeSets->children('ns2', true)->ItemAttributes->SmallImage->URL),
                            );

     }  else {

$amazonResult = array(
                            'isbn' => $ean,
            'ImageURL' => "",
                            );

}

I needed to use $item after the foreach statement.
