使用php使用命名空间定位XML

I'm new to XML and I'm having a hard time grabbing the MarketRent. I'm trying to target all the ILS_Unit with a certain id and grab the MarketRent nodeValue. But there is a namespace, which I register, but I'm receiving a blank page.

My PHP Code:

<?php
$doc = new DOMDocument;
$doc->preserveWhiteSpace = false;
$doc->load('http://mdoerrdev.com/xml/updates-mits.xml');

$xpath = new DOMXPath($doc);
$xpath->registerNamespace('MITS', "http://mdoerrdev.com/xml/updates-mits.xml");

$unitPrice = $xpath->evaluate("//ILS_Unit[@FloorplanId='550584']/Unit/MITS:Information/MITS:MarketRent");
    foreach($unitPrice as $up)  {
        var_dump($up);
    };
?>

The Input XML:

Input XML is too big, so you can find it here: http://mdoerrdev.com/xml/updates-mits.xml

    If you register the namespace, make sure the URI matches the one in the XML, change:

     $xpath->registerNamespace('MITS', "http://mdoerrdev.com/xml/updates-mits.xml");
    

    to

     $xpath->registerNamespace('MITS', "http://www.mitsproject.org/namespace");
