If you just want to print out the text inside the <p> tags, the use $textContent...

foreach($dom->getElementsByTagName('p') as $link) {
        echo $link->textContent;
        echo "<br />";
}

If you want the whole XML, you can output it using saveXML() with the node as the point to output from ...

foreach($dom->getElementsByTagName('p') as $link) {
        echo $dom->saveXML( $link);
        echo "<br />";
}

As this is HTML, you may want to replace the saveXML() call with saveHTML().
