I was trying to find a way to convert any xml feed into an associative array, I noticed many other people have looked for the same thing, and there has been many attempts, some of them have failed, I found the following way of doing it, credit goes to
http://gaarf.info/2009/08/13/xml-string-to-php-array/
I slightly changed the code, and here is the outcome.
function xmlNameSpaceToArray(SimpleXmlIterator $xml, $nameSpaces=Null){
$output = Null;
$preparedArray = array();
for($xml->rewind(); $xml->valid(); $xml->next()) {
$key = $xml->key();
if(!isset($preparedArray[$key])) { $preparedArray[$key] = array(); $i=0; }
else $i = count($preparedArray[$key]);
$simple = true;
foreach($xml->current()->attributes() as $k=>$v) {
$preparedArray[$key][$i][$k]=(string)$v;
$simple = false;
}
if($nameSpaces) foreach($nameSpaces as $nid=>$name) {
foreach($xml->current()->attributes($name) as $k=>$v) {
$preparedArray[$key][$i][$nid.':'.$k]=(string)$v;
$simple = false;
}
}
if($xml->hasChildren()) {
if($simple) $preparedArray[$key][$i] = xmlNameSpaceToArray($xml->current(), $nameSpaces);
else $preparedArray[$key][$i]['content'] = xmlNameSpaceToArray($xml->current(), $nameSpaces);
} else {
if($simple) $preparedArray[$key][$i] = strval($xml->current());
else $preparedArray[$key][$i]['content'] = strval($xml->current());
}
$i++;
}
$output = $preparedArray;
return $preparedArray;
}
function xmlToArray($xmlFilePath){
$xml = new SimpleXmlIterator($xmlFilePath , null, true);
$nameSpaces = $xml->getNamespaces(true);
$output = xmlNameSpaceToArray($xml,$nameSpaces);
return $output;
}
$xmlFilePath = 'http://forums.devshed.com/rss/feed-5.xml';
$output = xmlToArray($xmlFilePath);
print_r($output);
What I'm trying to find out now is potential problems this could have, the goal is to make this work for EVERY well structured XML feed, without any php warnings, notices and without losing any data.
Can you find a flaw in this or a feed that doesn't work? It worked for everything I tested it for.

The syntax looks something like this for your example
<aaaa Version="1.0">
<bbb>
<cccc>
<dddd Id="id:pass" />
<eeee name="hearaman" age="24" />
</cccc>
</bbb>
</aaaa>
PHP code
<?php
$xml = new SimpleXMLElement($xmlString);
echo $xml->bbb->cccc->dddd['Id'];
echo $xml->bbb->cccc->eeee['name'];
// or...........
foreach ($xml->bbb->cccc as $element) {
foreach($element as $key => $val) {
echo "{$key}: {$val}";
}
}

Easiest way to do this is to use the built in functions, then convert to an array.
<?php
$obj = simplexml_load_string($xml); // Parse XML
$array = json_decode(json_encode($obj), true); // Convert to array
?>

This piece of XML seems to break it.
