Note that even though getElementsByTagName returns a NodeList which is defined as a list of DOMNodes, you're actually getting a list of DOMElements. That allows to call getElementsByTagName on each of the results.
$tables = $doc->getElementsByTagName('table');
foreach ($tables as $table) {
$trs = $table->getElementsByTagName('tr');
// etc...
}

Be aware that this function returns all descendants, not just immediate children.

A simple function that uses this method to print the nodes it finds in an xml document. Improvements welcomed.
<?php
function printTags($tag){
$node = $this->doc->getElementsByTagName($tag);
for($c = 0; $c<$node->length; $c++){
$text[$c] =$this->doc->saveXML($node->item($c));
echo $text[$c];
}
}
?>
