Shopify webhook xml file array using php

Question

I am using shopify webhook to update ms sql server when order fullfilled the belos are the code and xml file i get from shopify webhook but in order.xml file there are two key tags of "line-item" one in the "order" tag and the other is in "fullfillments" tag so i got duplicated value from order.xml file. How can i get only one value from "line-item" tag, please help me. Thank you so much in advance.

The php code:

$itemList2 = $dom->getElementsByTagName('line-item');


foreach($itemList2 as $item) {

$qty='';
$sku='';
$lineitemprice='';
$linetax='';

foreach($item->childNodes as $child) {

if ($child->localName == 'quantity') {
$qty = $child->textContent;
}
if ($child->localName == 'sku') {
$sku = $child->textContent;
}
if ($child->localName == 'price') {
$lineitemprice = $child->textContent;
}
if ($child->localName == 'linetax') {
$linetax = $child->textContent;
}
}   

and the order.xml file from shopify webhook

<?xml version="1.0" encoding="UTF-8"?>

Answer 1

You could use XPath, for example:

$xpath = new DOMXpath($dom);
$itemList2 = $xpath->query("/order/line-items/line-item"); // absolute path

Using a relative path like this should work too:

$itemList2 = $xpath->query("line-items/*");
