[marcio]

Hej mam male pytanie mam taka oto tablice:

[PHP] pobierz, plaintext 
$configs['plugins_settings'] = array(
									'compatible' => array('comment', 'polling'),
									'after' => array(
													'readNews' => array(
																		'description' => 'Czytamy news-a',
																		'plugins' => array(
																						'comment' => array(
																											'settings' => array('segment_ref' => 0),
																											'actions' => array('submit', 'delete')
																										  )
																						  )
																		),
													'delete' => array(
																		'description' => 'Usuwamy news-a',
																		'plugins' => array(
																						'comment' => array(
																											'settings' => array('segment_ref' => 3),
																											'actions' => array('submit', 'delete')
																										  )
																						  )
																		)
													  )
								  );
[PHP] pobierz, plaintext 

A w xml mam to tak:

[XML] pobierz, plaintext 
<?xml version="1.0" encoding="UTF-8"?>
<config>
	<plugins_settings>
		<compatible>
			<plugin>comment</plugin>
			<plugin>polling</plugin>
		</compatible>
		<after>
			<readNews>
				<description>Czytamy news-a</description>
				<plugins>
					<comment>
						<settings>
							<segment_ref>0</segment_ref>
							<actions>
								<action>submit</action>
								<action>delete</action>
							</actions>
						</settings>
					</comment>
				</plugins>
			</readNews>
		</after>
	</plugins_settings>
</config>
[XML] pobierz, plaintext 

I teraz chodzi mi dokladnie o sekcje <plugin></plugin> i <action></action>
I mam taki kod ktory to daje do tablicy php:

[PHP] pobierz, plaintext 
<?php

require_once(DIR_INTERFACES.'IConfig.php');
 
class Vf_Config_Xml_Adapter_Exception extends Exception { }
 
class Vf_Config_Xml_Adapter implements IConfig
{
 
	public function load($config_path)
	{
		if(file_exists($config_path))
		{
			$xml = new SimpleXMLElement($config_path, 0, true);
			return $this -> _XmlToArray($xml);
		}
		else
		{
			throw new Vf_Config_Xml_Adapter_Exception("Nie zaladowano konfiguracji: ".$config_path);
		}
	}
 
 
	public function isAcceptSuffix($suffix)
	{
		if($suffix == 'xml')
			return true;
		return false;
	}
 
 
	private function _XmlToArray($xml_object)
	{
		$config = array();
		if(is_object($xml_object) && $vars = get_object_vars($xml_object))
		{
			foreach($vars as $key => $value)
			{
				if(!is_object($value))
				{
					$config[$key] = $value;
				}
				else
				{
					$config[$key] = $this -> _XmlToArray($value);
				}
			}
			return $config;
		}
		return $xml_object;
	}
}
?>
[PHP] pobierz, plaintext 

Rezultat jest dobry oprocz tych 2 sekcji zwraca mi(czesc tablicy zwiazana tylko z tymi sekcjami):

Array ( [plugin] => Array ( [0] => comment [1] => polling )
Array ( [action] => Array ( [0] => submit [1] => delete ) )

A chcialbym miec:

Array ( [0] => comment [1] => polling )
Array ( [0] => submit [1] => delete )

A dodaje mi nazwe seksji i potem tablice.
Myslalem to zrobic na 2 sposoby:
1)Sprawdzac czy dana sekja ma wiecej elementow jesli tak iterowac po niej i dawac $key => $value do tablicy
2)Zamiast:

[XML] pobierz, plaintext 
<plugin>comment</plugin>
<plugin>polling</plugin>
[XML] pobierz, plaintext 

Zrobic:

[XML] pobierz, plaintext 
<plugin key="0">comment</plugin>
<plugin key="1">polling</plugin>
[XML] pobierz, plaintext 

I czytac wartosci atrybutu key

Czy idzie to zrobic w prostszy sposob?
