The Note You're Voting On

Here is my simple SimpleXML wrapper function.
As far as I can tell, it does the same as Julio Cesar Oliveira's (above).
It parses an XML string into a multi-dimensional associative array.
The second argument is a callback that is run on all data (so for example, if you want all data trimmed, like Julio does in his function, just pass 'trim' as the second arg).
<?php
function unserialize_xml($input, $callback = null, $recurse = false)
/* bool/array unserialize_xml ( string $input [ , callback $callback ] )
 * Unserializes an XML string, returning a multi-dimensional associative array, optionally runs a callback on all non-array data
 * Returns false on all failure
 * Notes:
    * Root XML tags are stripped
    * Due to its recursive nature, unserialize_xml() will also support SimpleXMLElement objects and arrays as input
    * Uses simplexml_load_string() for XML parsing, see SimpleXML documentation for more info
 */
{
    // Get input, loading an xml string with simplexml if its the top level of recursion
    $data = ((!$recurse) && is_string($input))? simplexml_load_string($input): $input;
    // Convert SimpleXMLElements to array
    if ($data instanceof SimpleXMLElement) $data = (array) $data;
    // Recurse into arrays
    if (is_array($data)) foreach ($data as &$item) $item = unserialize_xml($item, $callback, true);
    // Run callback and return
    return (!is_array($data) && is_callable($callback))? call_user_func($callback, $data): $data;
}
?>
