To read a namespace node you have to use the children method.

<?php

$xml 
= <<<XML
<?xml version="1.0" encoding="UTF-8"?>
<people xmlns:p="http://example.org/ns" xmlns:t="http://example.org/test">
    <p:person id="1">John Doe</p:person>
    <p:person id="2">Susie Q. Public</p:person>
</people>
XML;

$sxe = new SimpleXMLElement($xml);

$ns $sxe->getNamespaces(true);

$child $sxe->children($ns['p']);

foreach (
$child->person as $out_ns)
{
    echo 
$out_ns;
}

?>

If the namespace is nested in the xml, then you will have to loop over the nodes.

<?php




$xml 
= <<<XML
<?xml version="1.0" encoding="UTF-8"?>
  <people xmlns:p="http://example.org/ns" xmlns:t="http://example.org/test">
      <items>
            <title>This is a test of namespaces and my patience</title>
            <p:person id="1">John Doe</p:person>
            <p:person id="2">Susie Q. Public</p:person>
            <p:person id="1">Fish Man</p:person>
      </items>
  </people>
XML;




$sxe = new SimpleXMLElement($xml);




foreach (
$sxe as $out_ns)
{
    $ns $out_ns->getNamespaces(true);




    $child $out_ns->children($ns['p']);




    foreach ($child as $out)
    {
        echo $out "<br />";
    }
}
?>
