Another option is the SimpleXML extension (I believe it comes standard with most php installs.)

http://php.net/manual/en/book.simplexml.php

The syntax looks something like this for your example

$xml = new SimpleXMLElement($xmlString);
echo $xml->bbb->cccc->dddd['Id'];
echo $xml->bbb->cccc->eeee['name'];
// or...........
foreach ($xml->bbb->cccc as $element) {
  foreach($element as val) {
   echo "{$key}: {$val}";
  }
}

I created a package that works very well with Laravel to help you convert XML into an array.

https://github.com/mtownsend5512/xml-to-array

Install it, and you can make use of the global helper function for Laravel xml_to_array.

Because your XML is malformed, I tried my best to fix it so I could provide an example:

    $xml = <<<XML

XML;

dd(xml_to_array($xml));

Now your XML will be a valid array which can be manipulated. Because of your extensive use of attributes you will have a lot of data clean up to do. I recommend wrapping it in a Laravel Collection by doing collect($xml), then checking Laravel's Collection documentation to figure out the best way to transform the data in the way you want it.

a short one:

<?php

$test_array = array (
  'bla' => 'blub',
  'foo' => 'bar',
  'another_array' => array (
    'stack' => 'overflow',
  ),
);
$xml = new SimpleXMLElement('<root/>');
array_walk_recursive($test_array, array ($xml, 'addChild'));
print $xml->asXML();

results in

<?xml version="1.0"?>
<root>
  <blub>bla</blub>
  <bar>foo</bar>
  <overflow>stack</overflow>
</root>

keys and values are swapped - you could fix that with array_flip() before the array_walk. array_walk_recursive requires PHP 5. you could use array_walk instead, but you won't get 'stack' => 'overflow' in the xml then.
