[fw-general] Zend_Dom_Query and XML

[Hector Virgen]

I am using the 1.6.2 branch of ZF, and I'm having trouble using
Zend_Dom_Query with a simple XML file. I have followed the example from
http://framework.zend.com/manual/en/zend.dom.query.html#zend.dom.query.methods.zenddomquerybut
it doesn't seem to be working for me. Am I doing something wrong?
Here's my XML:

<?xml version="1.0" encoding="utf-8"?>
<Manifest xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:xsd="http://www.w3.org/2001/XMLSchema";
xmlns="http://platform.point2.com/schemas/2.0/manifest";>
  <BuildDate>2008-05-15T01:18:25.0434624Z</BuildDate>
  <Listings>
    <ListingDocument name="listings-1.xml" />
    <ListingDocument name="listings-10.xml" />
    <ListingDocument name="listings-2.xml" />
    <ListingDocument name="listings-3.xml" />
    <ListingDocument name="listings-4.xml" />
    <ListingDocument name="listings-5.xml" />
    <ListingDocument name="listings-6.xml" />
    <ListingDocument name="listings-7.xml" />
    <ListingDocument name="listings-8.xml" />
    <ListingDocument name="listings-9.xml" />
  </Listings>
  <Orders />
</Manifest>

Here's my PHP code:

<?php
$manifest = 'manifest.xml';
$xml = file_get_contents($manifest);
var_dump($xml); // <-- looks good

$dom = new Zend_Dom_Query();
$dom->setDocumentXml($xml);
var_dump($dom); // <-- looks good

$listings = $dom->query('Listings ListingDocument');
var_dump($listings->getCssQuery()); // <-- looks good
var_dump(count($listings)); // <-- 0  not correct, should be 10

// This dumps out "NULL" just once.
foreach ($listings as $listing) {
    var_dump($listing);
}

?>

Thanks for your help :)
