Classe: XML_Unserializer  - X-Ref

XML_Unserializer

class to unserialize XML documents that have been created with
XML_Serializer. To unserialize an XML document you have to add
type hints to the XML_Serializer options.

If no type hints are available, XML_Unserializer will guess how
the tags should be treated, that means complex structures will be
arrays and tags with only CData in them will be strings.

<code>
require_once 'XML/Unserializer.php';

//  be careful to always use the ampersand in front of the new operator
$unserializer = &new XML_Unserializer();

$unserializer->unserialize($xml);

$data = $unserializer->getUnserializedData();
<code>

Possible options for the Unserializer are:

1. complexTypes => array|object
This is needed, when unserializing XML files w/o type hints. If set to
'array' (default), all nested tags will be arrays, if set to 'object'
all nested tags will be objects, that means you have read access like:

<code>
require_once 'XML/Unserializer.php';
$options = array('complexType' => 'object');
$unserializer = &new XML_Unserializer($options);

$unserializer->unserialize('http://pear.php.net/rss.php');

$rss = $unserializer->getUnserializedData();
echo $rss->channel->item[3]->title;
</code>

2. keyAttribute
This lets you specify an attribute inside your tags, that are used as key
for associative arrays or object properties.
You will need this if you have XML that looks like this:

<users>
<user handle="schst">Stephan Schmidt</user>
<user handle="ssb">Stig S. Bakken</user>
</users>

Then you can use:
<code>
require_once 'XML/Unserializer.php';
$options = array('keyAttribute' => 'handle');
$unserializer = &new XML_Unserializer($options);

$unserializer->unserialize($xml, false);

$users = $unserializer->getUnserializedData();
