Note that you must provide the namespace if you want to access an attribute of a non-default namespace:

Consider the following example:

<?php
$xml = <<<XML
<?xml version="1.0"?>
<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet"
 xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet">
 <Table Foo="Bar" ss:ExpandedColumnCount="7">
 </Table>
</Workbook>
XML;

$sxml = new SimpleXMLElement($xml);

/**
 * Access attribute of default namespace
 */
var_dump((string) $sxml->Table[0]['Foo']);
// outputs: 'Bar'

/**
 * Access attribute of non-default namespace
 */
var_dump((int) $sxml->Table[0]['ExpandedColumnCount']);
// outputs: 0

var_dump((int) $sxml->Table[0]->attributes('ss', TRUE)->ExpandedColumnCount);
// outputs: '7'
?>
