Getting the text part of a node using php Simple XML

Given the php code:

$xml = <<<EOF
<articles>
<article>
This is a link
<link>Title</link>
with some text following it.
</article>
</articles>
EOF;

function traverse($xml) {
    $result = "";
    foreach($xml->children() as $x) {
        if ($x->count()) {
            $result .= traverse($x);
        }
        else {
            $result .= $x;
        }
    }
    return $result;
}

$parser = new SimpleXMLElement($xml);
traverse($parser);

I expected the traverse () function to return:

This is a link Title with some text following it.

However, it only returns:

Title

Is there a way to get the expected result using simpleXML (obviously, for the purpose of consuming data, and not just returning it, as in this simple example)?

Thank you N.
