PHP, XML, and parsing into arrays

[zerodash]

I didn't want do derail any threads, so I decided to post this here:

The following problem I am having is with code derived from the google_checkout contribution, which I need to modify a bit to match my needs.

 

See this nifty XML parser:

 

<?

class XmlParser {
var $params= array();
var $level = array();

function XmlParser($input) {
$xmlp = xml_parser_create();
xml_parse_into_struct($xmlp, $input, $vals, $index);
xml_parser_free($xmlp);
$this->updateMembers($vals, $index);
}

// Takes the data and puts it into PHP array  
function updateMembers($vals, $index) {
foreach ($vals as $xml_elem) {
 if ($xml_elem['type'] == 'open' ) {
$this->level[$xml_elem['level']] = strtolower($xml_elem['tag']);
 }
 elseif ($xml_elem['type'] == 'complete') {
$xml_elem['tag'] = strtolower($xml_elem['tag']);
$start_level = 1;
$php_stmt = '$this->params';
while($start_level < $xml_elem['level']) {
  $php_stmt .= '[$this->level['.$start_level.']]';
  $start_level++;
}
$php_stmt .= '[$xml_elem[\'tag\']] = $xml_elem[\'value\'];';
eval($php_stmt);


 }	
}
}

function getRoot() {
return $this->level[1];	
}

function getData() {
return $this->params;	
}
}
$xmlp = new XmlParser($xml_response);
$root = $xmlp->getRoot();
$data = $xmlp->getData();
?>

 

It works really well except for one problem- When parsing XML formatted something like shown below, it only stores one "item" from the "item" element in the resulting array.

 

 

<order>
 <date>2006-09-19</date>
 <cart>
<items>
  <item>
	<quantity>1</quantity>
	<unit-price currency=\"USD\">80.0</unit-price>
	<item-name>Garbage</item-name>
	<item-description>Smelly</item-description>
  </item>
  <item>
	<quantity>2</quantity>
	<unit-price currency=\"USD\">10.0</unit-price>
	<item-name>Another Item</item-name>
	<item-description>This item Sucks</item-description>
  </item>	  
  <item>
	<quantity>3</quantity>
	<unit-price currency=\"USD\">450.0</unit-price>
	<item-name>nachos</item-name>
	<item-description>Cheesey</item-description>
  </item>	  
</items>
 </cart>
</order>

 

 

For instance, when I output echo $data[$root]['cart']['items']['item']['item-name'] . "<br>"; , it will only echo "nachos". Presumably because as it loops through the parser, it copies over the "item" element over and over.

 

Does anyone have any idea what I can do to make sure all "items" are stored in this array? I cannot alter the XML in any way, so the parser needs to be fixed.

 

Thanks in advance for any input.
