I have this php script that displays the contents of an xml file like this:

<?xml version="1.0" encoding="iso-8859-1"?>
<ico title="Lino Adium Dock" img="enhancedlabs/lino_adium_dock.png" url="http://www.enhancedlabs.com"/>
<ico title="The real Christmas" img="enhancedlabs/2005.png" pc="enhancedlabs/the_ico.zip" url="http://www.enhancedlabs.com"/>
<ico title="Mac Mini" img="enhancedlabs/mac_mini.gif" pc="enhancedlabs/mac_mini_icons.zip" url="http://www.enhancedlabs.com"/>

The script to print the above xml file is like this:


class XMLparser{
	var $main = array();
	var $currentparent = "default";
	function XMLparser($inputxmlstring){
		$lines = explode("\n",$inputxmlstring);
		$n = 0;
		foreach ($lines as $line){
			if (trim($line) == "") continue;
			$line = trim($line);
			$s_regex = "/<([a-z]+)>/i";	
			$e_regex = "/<\/([a-z]+)>/i";
			$s_matches = null; $e_matches = null;
			$start = preg_match($s_regex, $line, $s_matches);
			$end = preg_match($e_regex, $line, $e_matches);
			if ($s_matches == null && $e_matches == null){
				//this is a node
				$attributes = array();
				preg_match_all("/([a-z]+)=\"([^\"]*)\"/i", $line, $attributes);
				$names = $attributes[1];
				$values = $attributes[2];
				for ($i = 0; $i < count($names); $i++){
					$name = $names[$i];
					$value = $values[$i];
					$this->main[$this->currentparent][$n][$name] = $value;
			}else if($e_matches == null){
				//this is a start
				$parentname = $s_matches[1];
				$this->currentparent = $parentname;
				$n = 0;

$XML = file_get_contents("icons.xml");

$instance = new XMLparser($XML);
$parseddata = $instance->main;

//get all the nodes under the "icons" parent
foreach ($parseddata['icons'] as $node){
	echo "Title: " . $node['title'];
	echo " Source: " . $node['img'];
	echo " Credits: " . $node['url'] . "<br />";

Question is: how should the parser look like in order to parse a new XML file formated like this:

<?xml version="1.0" encoding="iso-8859-1"?>

Apart from the commented out section at the bottom of the page, I can't see any 'tag-specific' code in there, so I'd have thought that it should just work with the new XML too.

Advice to MySQL users: Get phpMyAdmin and test your queries work there first, take half the hassle out of diagnosis, also check the reserved words list.

The commented area at the end are the ones that display the xml in site but the new xml I want to read has an additional level and I do not know what to modify in order to read that new format.
//The php script was made by someone else, I am not good with php.
