There are different ways to access elements and attributes of XML documents
with SimpleXML (XPath, etc), but generally speaking, attributes can be
accessed as associative array values.
Here's an example:
<?php
$xml = <<<XML
<?xml version="1.0" ?>
<document type="db download">
<packages total_weight="15.8" total_packages="1">
<package length="147" width="5" height="5" weight="15.8"/>
</packages>
</document>
XML;
$sxml = new SimpleXMLElement($xml);
// Access the first package
$package = $sxml->packages->package[0];
echo sprintf(
"Package Dimensions: %sx%sx%s Weight: %s\n",
$package['length'],
$package['width'],
$package['height'],
$package['weight']
);
// Find all packages
foreach($sxml->packages->package as $package) {
echo sprintf(
"Package Dimensions: %sx%sx%s Weight: %s\n",
$package['length'],
$package['width'],
$package['height'],
$package['weight']
);
}

So if the above is valid XML, is there a specific name for this
approach? Is there a benefit for doing it this way instead of nested
nodes? Might this be considered older method?

No, it's not an older method. There is no absolute definition of when to use
elements versus attributes. There are, however, some attempts at defining
general principles:
