What could cause the above to occur?
All I'm getting is SimpleXMLElement Object ( ), it's not giving any indication as to why the object is empty. If there's a problem in the XML, it needs to say so.

1Check the use of namespaces within your XML. This is not necessarily a problem in the XML, but you could be trying to read a namespaced node without using the appropriate namespace... which will give you an empty object. Show us the XML object that you're trying to readMark Baker– Mark Baker2011-03-17 11:50:38 +00:00Commented Mar 17, 2011 at 11:50

An example of namespaces.
$xmlData = <<<EOXML
<?xml version="1.0"?>
<?mso-application progid="Excel.Sheet"?>
<Workbook xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet"
xmlns:html="http://www.w3.org/TR/REC-html40">
<ExcelWorkbook>
<ss:WindowHeight>13995</ss:WindowHeight>
<ss:WindowWidth>28455</ss:WindowWidth>
<ss:WindowTopX>240</ss:WindowTopX>
<ss:WindowTopY>510</ss:WindowTopY>
<ss:ProtectStructure>False</ss:ProtectStructure>
<ss:ProtectWindows>False</ss:ProtectWindows>
</ExcelWorkbook>
</Workbook>
EOXML;
$xml = new SimpleXMLElement($xmlData);
$namespaces = $xml->getNamespaces(true);
echo 'Show namespaces used';
var_dump($namespaces);
echo 'Read child nodes without using namespace'
$xNodes1 = $xml->ExcelWorkbook->children;
var_dump($xNodes1);
echo 'Read child nodes using namespace'
$xNodes2 = $xml->ExcelWorkbook->children($namespaces['ss']);
var_dump($xNodes2);
Result is:
Show namespaces used
array
'ss' => string 'urn:schemas-microsoft-com:office:spreadsheet' (length=44)
Read child nodes without using namespace
object(SimpleXMLElement)[4]
Read child nodes using namespace
object(SimpleXMLElement)[5]
public 'WindowHeight' => string '13995' (length=5)
public 'WindowWidth' => string '28455' (length=5)
public 'WindowTopX' => string '240' (length=3)
public 'WindowTopY' => string '510' (length=3)
public 'ProtectStructure' => string 'False' (length=5)
public 'ProtectWindows' => string 'False' (length=5)
