Answer 1

My Answer is not about DomDocument Query but can solve your problem easily.
There is a Library named SIMPLEHTMLDOM ! You can do great things with it.
Example :
// Create DOM from URL or file
$html = file_get_html('http://www.google.com/');
// Find all images
foreach($html->find('img') as $element)
echo $element->src . '<br>';
// Find all links
foreach($html->find('a') as $element)
echo $element->href . '<br>';
Full Documentation (Power of this Lib) is Here.

Try this,
$xquery = '//a'; // you will get all anchor tags now
$links = $xpath->query($xquery);
foreach ($links as $el) {
echo strip_tags($doc->saveHTML($el)).'<br/>';
}
Try this to get in a single line,
$xpath = new DOMXPath($doc);
$xquery = '//tr[td[a]]';
$links = $xpath->query($xquery);
foreach ($links as $el) {
echo strip_tags($doc->saveHTML($el)).'<br/>';
}
