[RESOLVED] nested xml for each

[scrupul0us]

xml:

<?xml version="1.0" encoding="iso-8859-1"?>
<products xml:space="preserve">
	<item>
	...
	<price>
		<p1>5</p1>
		<p2>10</p2>
	</price>
	</item>
</products>

now... i can output all the other elements (not shown) just fine with this:

$xmlFileName = 'products.xml';
$xml = simplexml_load_file($xmlFileName);
$i=0;
foreach ($xml->item as $item) 
{
//...
}
?> 

now, within THAT foreach i need to foreach through each price

all i can think of is this:

foreach ($item->price as $price)
{

}

but i cant think of how to call each underlying price

got it:

$i = 1;
$price = "p".$i;

while($item->price->$price)
{
echo $item->price->$price;
$i++;
$price = "p".$i;
}
