Question

I have a xml parser that returns an associative array. Here’s the structure:

<addresses id="123">
  <anonymous-address> <test>data 1 </test>
  </anonymous-address>
</addresses>

print_r($this->params) will return 
Array
(
    [addresses] => Array
        (
            [id] => 123
            [anonymous-address] => Array
                (
                    [0] => Array
                        (                                
                            [test] => Array
                                (
                                    [VALUE] => data 1
                                )))))

This array then gets passed through list() as:

list($root, $data) = $parsedXML;

Then I attempt to get an id attribute from root and read to do it this way:

$id = $data[$root]['id'];

Edit: This works for all but one $root value which it 400’s for. This case of the switch ($root) has the same code as the others, so I have no idea why it errs only there.

var_dump($root, $data) outputs

string (9)  "addresses"
array(1)  {
    ["addresses"]=>
    array(2)  {
        ["id"]=>
        string(3)  "123"
        ["anonymous-address"]=>
        array(1)  {
            ["VALUE"]=>
            string(7)  "data 1 "
        }
    }
}

Answer 1

$a = list($root, $data);

now $a will be:

array(0 => $root, 1 => $data);

so you can get them like this:

$a[0], $a[1]

so probably

$id = $a[1][$a[0]]['id'];
