Getting names of child nodes in XML

[davidannis]

I am trying to get the names of the children nodes in XML

 

Here is the code:

        foreach ($pos->children() as $child) {
            echo "I never get here";
            echo $child->getName() . "\n";
        }
        //}
        echo "but the node has children---<br>";
        print_r($pos);

which I modeled on the code from http://www.php.net/manual/en/simplexmlelement.getname.php

 

and here is a sample of the output:

SimpleXMLElement Object
(
    [n] => SimpleXMLElement Object
        (
        )

)
but the node has children---
SimpleXMLElement Object
(
    [int] => SimpleXMLElement Object
        (
        )

)
but the node has children---
SimpleXMLElement Object
(
    [n] => SimpleXMLElement Object
        (
        )

)

Why can't I go through the chldren with foreach?

What's the source XML?

[davidannis]

The source XML is huge but here's a sample:

<entry>
        <ent_seq>1000320</ent_seq>
        <k_ele>
            <keb>彼処</keb>

        <k_ele>
