We upgraded a legacy CentOS box from PHP 5.3.X to 5.4.35 and our XML code started to break.

I understand that these versions are not supported but for this particular project this is the best we can do. The weird thing is that this code works in 5.3, 5.5, 5.6, 7.0 ... But not 5.4.35 on CentOS. Running the attached test script on that particular version will echo "> YOU HAVE FAILED... "

I'm looking for some help, duplicate bugs that explain what is going on, or workarounds.

Thank you for your time.

Test script:

// ------------------------------------------------------------------------------------------------
// Functions
// ------------------------------------------------------------------------------------------------

function _iterator2array($iterator)
    $array = array();
    for ($iterator->rewind(); $iterator->valid(); $iterator->next())
        if (!array_key_exists($iterator->key(), $array)) $array[$iterator->key()] = array();

        if ($iterator->hasChildren()) $array[$iterator->key()][] = _iterator2array($iterator->current());
            $attributes = (array)$iterator->current();
            $array[$iterator->key()][] = reset($attributes);

    return $array;

function _xml2array($xml)
    // Strip the XML header if there is one and add a parent container
    if (preg_match('/<\?xml.*\?>/', $xml)) $xml = '<?xml version="1.0" encoding="UTF-8"?><root>'.preg_replace('/<\?xml.*\?>/', '', $xml).'</root>';
    $iterator = new SimpleXMLIterator($xml, NULL);

    return _iterator2array($iterator);

// ------------------------------------------------------------------------------------------------
// Input
// ------------------------------------------------------------------------------------------------

$xml = '<?xml version="1.0" encoding="UTF-8"?>\n<shipment-info xmlns=""><shipment-id>178011488481085223</shipment-id><shipment-status>created</shipment-status><tracking-pin>123456789012</tracking-pin><links><link rel="self" href="" media-type="application/vnd.cpc.shipment-v2+xml"/><link rel="details" href="" media-type="application/vnd.cpc.shipment-v2+xml"/><link rel="group" href="" media-type="application/vnd.cpc.shipment-v2+xml"/><link rel="price" href="" media-type="application/vnd.cpc.shipment-v2+xml"/><link rel="label" href="" media-type="application/pdf" index="0"/></links></shipment-info>';
$response = _xml2array($xml);

// ------------------------------------------------------------------------------------------------
// Test
// ------------------------------------------------------------------------------------------------

if (empty($response['shipment-info'][0]['tracking-pin'][0])) {
    echo "> YOU HAVE FAILED... \n";
} else {
    echo "> SUCCESS! \n";

Expected result:
`$response['shipment-info'][0]['tracking-pin'][0] = '123456789012'

Actual result:
$response['shipment-info'][0]['tracking-pin'][0] = ''

Seems it was fixed in 5.5.27, which came with the fix for
and other similar bugs that were caused by whitespace issues. The change was fairly simple (within sxe_get_prop_hash) so you should be able to apply that to the 5.4 sources and build a custom patched version for yourself.
