Maybe you could use XPath queries. For example:

$doc = new DOMDocument();
$doc->loadHTML(...your html...);

$xpath = new DOMXPath($doc);
$query = '//table/tr/td';

$entries = $xpath->query($query);

foreach ($entries as $entry)
    print_r($entry->nodeValue); (*)

Just replace the line marked with (*) with code that suites your needs. Cheers.

It's hard to say what you are doing wrong if you don't say, what you are doing at all.

But in principle you must get a reference to the table (as a DOM element), then get the rows and cells (child nodes) and get the node value from there.

If your table is the only one in the document, you'll get it via $doc->getElementsByTagName('table')->item(0) (with $doc being the DOM document object).
