    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 />";
        }
    }
    ?>

    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;
    }

    ?>
