New Comment:
I will add a feature to unserialize tags with attributes in the next
release, currently working on it.

Description:
------------
XML_Unserializer works great for turning an XML file into an array, but
I can't figure out how to get attributes.
Here's a hypothetical example using http://pear.php.net/rss.php as a
base:
Array
(
[channel] => Array
(
[language] => en
[image] => Array
(
[url] => http://pear.php.net/gifs/pearsmall.gif
[link] => http://pear.php.net/
)
...
}
Now, I know this would be against the RSS spec (I just needed an
example XML file), but what if "image" had width and height
attributes?
[image] => Array
(
[url] => http://pear.php.net/gifs/pearsmall.gif
[link] => http://pear.php.net/
[attr_width] => 104
[attr_height] => 50
)
All is well and good there. Now imagine that "link" has a "title"
attribute:
[image] => Array
(
[url] => http://pear.php.net/gifs/pearsmall.gif
[link] => Array
{
[0] => http://pear.php.net/
[attr_title] => PEAR
}
}
Suddenly, "link" has changed from a string to an array. If the
attributes are optional, you could never be sure which it would be. The
0 is used as a key to avoid naming conflicts that could come up with
"content" or "data".
One solution would be to make every value an array. Strings would
become arrays with only 1 element (key 0).
Reproduce code:
---------------
require_once 'XML/Unserializer.php';
$options = array('complexType' => 'array');
$unserializer = &new XML_Unserializer($options);
$unserializer->unserialize('http://pear.php.net/rss.php', true);
$rss = $unserializer->getUnserializedData();
echo "<pre>";
print_r($rss);
echo "</pre>";
