parsing xml

[blinks]

I'm trying to parse some XML code. It is working OK at the parent level (e.g. orderby), but not at the child level (communities, PIDs). I'm sure the answer is really simple, but I'm just not seeing it, so I'd appreciate some guidance.

 

Here's the XML -

<?php
$xmlstr = <<<XML
<?xml version="1.0" encoding="UTF-8" ?> 
<mypids>
<orderby>PID</orderby>
<communities>
	<community>278</community>
	<community>788</community>
</communities>
<PIDs>
	<pid>7888</pid>
	<pid>7889</pid>
</PIDs>
</mypids>
XML;
?>

 

and here's the php -

 <?php 

include_once("example2.php"); 

$xml = new SimpleXMLElement($xmlstr); 

//read xml into variables
$orderby = (string) $xml->orderby;
echo $orderby.'<br />';

for($i=0;$i<sizeof($xml->communities->community);$i++){
   foreach($xml->communities->community[$i] as $xcommunity){
      echo $xcommunity."<br/>";
   }
}

for($i=0;$i<sizeof($xml->PIDs->pid);$i++){
   foreach($xml->PIDs->pid[$i] as $xpids){
      echo $xpids."<br/>";
   }
}
?>

OK, got it -

<?php
include_once("example2.php"); 
$xml = new SimpleXMLElement($xmlstr); 
//read xml into variables
$orderby = (string)$xml->orderby;
echo $orderby.'<br />';
foreach ($xml->communities->community as $comm) {
echo $comm.'<br />';
}

foreach ($xml->PIDs->pid as $ids) {
echo $ids.'<br />';
}
?>
