How to read large XML node of SimpleXML - php

Question

Can anyone help me with read large file?
I reading and item like that:
$xmlReader = new XMLReader();
$xmlReader->open($path);
while ($xmlReader->read() && $xmlReader->name !== 'item') ;
while ($xmlReader->name == 'item')
{
$node = new SimpleXMLElement($xmlReader->readOuterXML());
foreach($node->properties as $property)
{
var_dump($property->price); //empty class SimpleXMLElement
var_dump($property->attributes()); //empty class SimpleXMLElement
}
$xmlReader->next('item');
}
$xmlReader->close();
So i cant to read $property->price because i receive empty class SimpleXMLElement
The same situation with attribute sku i also receive empty class SimpleXMLElement
And i can't convert in (string) because i receive empty string.

Answer 1

It should be
foreach($node->properties->property as $property)
because it's only one <properties> elements but many <property> elements.
See Example #4 Accessing non-unique elements in SimpleXML in the PHP Manual:
When multiple instances of an element exist as children of a single parent element, normal iteration techniques apply.
<?php
include 'example.php';
$movies = new SimpleXMLElement($xmlstr);
/* For each <character> node, we echo a separate <name>. */
foreach ($movies->movie->characters->character as $character) {
echo $character->name, ' played by ', $character->actor, PHP_EOL;
}
?>
