Traverse XML file to find products recursively - php

Question

I am trying to read remote XML file to find products in a specific category. I am facing issue because XML file has nested categories and each category has products. I need help in preparing a recursive function which will output products from a specific category given the category name.
Here is the code i have started with
<?php
$xml = simplexml_load_file('https://www.deere.com/en/us-en.taxonomy');
getProducts($xml);
function getProducts($xml) {
foreach ($xml as $obj) {
if ($obj->getName() == 'en_us_tractors') { //if category name is en_us_tractors
if ($obj->children()) {
foreach ($obj->children() as $child) {
echo '<h1>' . $child->name . '</h1>';
if ($child->products) {
foreach ($child->products as $product) {
foreach ($product as $p) {
echo 'sku is ' . $p->sku . '<br>';
echo 'path is ' . $p->path . '<br>';
}
}
}
}
}
}
}
}

It's simple to use XPath to find the data, this finds all of the products inside the category you want...
$xml = simplexml_load_file('https://www.deere.com/en/us-en.taxonomy');
$products = $xml->xpath("//en_us_tractors//products/*");
foreach ( $products as $product ){
echo $product->sku."/".$product->path.PHP_EOL;
}
