Застрял в xml

Раньше передавал одномерный массив в xml

<?xml version="1.0" encoding="utf-8"?>
<root>
  <params>
      <delete>1</delete>
      <status>1</status>
	...
  </params>
</root>

и парсил его такой конструкцией

function get_method_params($xml)
{
	$res = array();

	$params = $xml->getElementsByTagName('params');

	foreach($params as $nodes)
	{
		$values = $nodes->getElementsByTagName('*');

		foreach($values as $node)
		{
			$res[$node->nodeName] = $node->nodeValue;
		}
	}

	return $res;
}

но понадобилось передать многомерный массив

<?xml version="1.0" encoding="utf-8"?>
<root>
  <params>
	<key value="16">
      <status>0</status>
    </key>
    <key value="17">
      <status>1</status>
    </key>
	...
  </params>
</root>

в связи с этим возникла трудность правильно распарсить, т.к. вложенность может быть любая

подскажите пожалуйста, а то совсем запутался

Вообще, все уже давно придумано:

function xmlFull2Array($contents, $get_attributes=1) {
		if(!$contents) return array();
	
		if(!function_exists('xml_parser_create')) {
			//print "'xml_parser_create()' function not found!";
			return array();
		}
		//Get the XML parser of PHP - PHP must have this module for the parser to work
		$parser = xml_parser_create();
		xml_parser_set_option( $parser, XML_OPTION_CASE_FOLDING, 0 );
		xml_parser_set_option( $parser, XML_OPTION_SKIP_WHITE, 1 );
		xml_parse_into_struct( $parser, $contents, $xml_values );
		xml_parser_free( $parser );
	
		if(!$xml_values) return;//Hmm...
	
		//Initializations
		$xml_array = array();
		$parents = array();
		$opened_tags = array();
		$arr = array();
	
		$current = &$xml_array;
	
		//Go through the tags.
		foreach($xml_values as $data) {
			unset($attributes,$value);//Remove existing values, or there will be trouble
	
			//This command will extract these variables into the foreach scope
			// tag(string), type(string), level(int), attributes(array).
			extract($data);//We could use the array by itself, but this cooler.
	
			$result = '';
			if($get_attributes) {//The second argument of the function decides this.
				$result = array();
				if(isset($value)) $result['value'] = $value;
	
				//Set the attributes too.
				if(isset($attributes)) {
					foreach($attributes as $attr => $val) {
						if($get_attributes == 1) $result['attr'][$attr] = $val; //Set all the attributes in a array called 'attr'
						/**  :TODO: should we change the key name to '_attr'? Someone may use the tagname 'attr'. Same goes for 'value' too */
					}
				}
			} elseif(isset($value)) {
				$result = $value;
			}
	
			//See tag status and do the needed.
			if($type == "open") {//The starting of the tag '<tag>'
				$parent[$level-1] = &$current;
	
				if(!is_array($current) or (!in_array($tag, array_keys($current)))) { //Insert New tag
					$current[$tag] = $result;
					$current = &$current[$tag];
	
				} else { //There was another element with the same tag name
					if(isset($current[$tag][0])) {
						array_push($current[$tag], $result);
					} else {
						$current[$tag] = array($current[$tag],$result);
					}
					$last = count($current[$tag]) - 1;
					$current = &$current[$tag][$last];
				}
	
			} elseif($type == "complete") { //Tags that ends in 1 line '<tag />'
				//See if the key is already taken.
				if(!isset($current[$tag])) { //New Key
					$current[$tag] = $result;
	
				} else { //If taken, put all things inside a list(array)
					if((is_array($current[$tag]) and $get_attributes == 0)//If it is already an array...
							or (isset($current[$tag][0]) and is_array($current[$tag][0]) and $get_attributes == 1)) {
						array_push($current[$tag],$result); // ...push the new element into that array.
					} else { //If it is not an array...
						$current[$tag] = array($current[$tag],$result); //...Make it an array using using the existing value and the new value
					}
				}
	
			} elseif($type == 'close') { //End of tag '</tag>'
				$current = &$parent[$level-1];
			}
		}
	
		return($xml_array);
