Accessing value in PHP SoapClient response element with attribute

Question

I have a problem with processing a PHP SoapClient response...

I know that I can access response XML elements using object notation:

$client = new SoapClient($wsdl,$options);
$data=$client->Method(array('Param'=>"Value"));
$tmp = $data->Results->Asset->Attributes>Attribute;
var_dump($tmp);

The problem is when I am trying to reach element with some attribute... Here is part of the XML resposne:

<Results>
 <Asset>
  <Attributes>
   <Attribute Name="ID">0</Attribute>
   <Attribute Name="FirstName">John</Attribute>
   <Attribute Name="Size">Large</Attribute>
  </Attributes>
 </Asset>
 <Asset>
  <Attributes>
   <Attribute Name="ID">1</Attribute>
   <Attribute Name="FirstName">Bob</Attribute>
   <Attribute Name="Size">Medium</Attribute>
  </Attributes>
 </Asset>
 <Asset>
  <Attributes>
   <Attribute Name="ID">2</Attribute>
   <Attribute Name="FirstName">Frank</Attribute>
   <Attribute Name="Size">Small</Attribute>
  </Attributes>
 </Asset>
</Results>

How to get value from element "Attribute" with attribute "Size" using object notation? In print_r I am getting an array with stdClass inside (it is only a part of it)

[0] => stdClass Object
    (
        [Attributes] => stdClass Object
        (
            [Attribute] => Array
            (
                [0] => stdClass Object
                    (
                        [_] => 0
                        [Name] => ID
                    )

                [1] => stdClass Object
                    (
                        [_] => John
                        [Name] => FirstName
                    )

                [2] => stdClass Object
                    (
                        [_] => Large
                        [Name] => Size
                    )
            )
        )
    )
[1] => stdClass Object
    (
        [Attributes] => stdClass Object
        (
            [Attribute] => Array
            (
                [0] => stdClass Object
                    (
                        [_] => 1
                        [Name] => ID
                    )

                [1] => stdClass Object
                    (
                        [_] => Bob
                        [Name] => FirstName
                    )

                [2] => stdClass Object
                    (
                        [_] => Medium
                        [Name] => Size
                    )
            )
        )
    )
[2] => stdClass Object
    (
        [Attributes] => stdClass Object
        (
            [Attribute] => Array
            (
                [0] => stdClass Object
                    (
                        [_] => 2
                        [Name] => ID
                    )

                [1] => stdClass Object
                    (
                        [_] => Frank
                        [Name] => FirstName
                    )

                [2] => stdClass Object
                    (
                        [_] => Small
                        [Name] => Size
                    )
            )
        )
    )

I know that i can probably use

$client->__getLastResponse()

and parse with SimpleXMLElement but it does not seem optimal for me...

You should be able to access it at $data->Results->Asset->Attributes->Attribute[0]->_.

If you want to search for your value where the attribute is "size" then you will probably need a loop. It's hard to tell what your data looks like with such a small sample, but I don't believe more concise methods like array_column() will work with that structure.

<?php
foreach ($data->Results->Asset as $Asset) {
    foreach ($Asset->Attributes->Attribute as $Attribute) {
        if ($Attribute->Name === "Size") {
            echo $Attribute->_;
        }
    }
}
