使用DOMXPath在PHP中调用XML数据

I am having trouble extracting the XML data through my foreach loop because of the VehicleDescription tag within my XML output. The attributes within this tag change with every different request that is put through the app. So, I can't simply add VehicleDescription with all its attributes (Country="US" language="en" modelYear="2015" bestMakeName="Audi" bestModelName="A4" bestStyleName="4dr Sdn Auto quattro 2.0T Premium" bestTrimName="Premium") to the xPath, it needs to remain variable because different requests are processed through this code.

So far my code looks like the following. How can I edit it so it calls the MECHANICAL data through the foreach loop?

<!DOCTYPE html>
<html lang="en">

<head>
<meta charset="utf-8">
<title>Dynamically Generate Select Dropdowns 2</title>
<style type="text/css">
   select {display: block;margin-left: auto;margin-right: auto;}
</style>
</head>

<body>

  <?php

   $xml = file_get_contents('note.xml');
   $dom = new DOMDocument();
   $dom->loadXML($xml);
   $xpath = new domXpath($dom);

    foreach ($xpath- >query('//VehicleDescription/standard[header="MECHANICAL"]/description') as     $mechdescription) {
   $mecharray[] = $mechdescription->nodeValue ;
   }

    foreach ($mecharray as $mechanicaldescription){
   echo $mechanicaldescription ."

";
   }

  ?>

</body>
</html>

Here is the XML:

<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">

The problem is that there is a namespace on your VehicleDescription element. You need to register the namespace, then reference it in your XPath query. Give this a try:

<?php
$xml = file_get_contents('note.xml');

$dom = new DOMDocument();
$dom->loadXML($xml);

$xpath = new DOMXPath($dom);
$xpath->registerNamespace("x", "urn:description7b.services.chrome.com");
$result = $xpath->query('//x:standard/x:header[ . = "MECHANICAL"]/../x:description');

$mecharray = [];

foreach ($result as $mechdescription)
{
    $mecharray[] = $mechdescription->nodeValue;
}

foreach ($mecharray as $mechanicaldescription)
{
    echo $mechanicaldescription . "

";
}
