Use DOM to transform HTML table to PHP’s array

PHP5’s DomDocument

$tableArray = array();
$dom  = new DomDocument();
$dom->preserveWhiteSpace = false;
$dom->loadHTML($xmlstr);
// return DOMNodeList
$rows = $dom->getElementsByTagName('tr');

// loop through each row
// to work with DOMNode (nodeName, nodeType, parentNode, nodeValue, getAttribute
for ($rowIndex  = 0, $length = $rows->length; $rowIndex < $length; $rowIndex++) {

    // DOMElement
   $currentRow = $rows->item($rowIndex);
   // the same to while($currentRow->hasChildNodes())
   // or foreach ($rows->item($rowIndex)->childNodes as $child) {

   if (null   !== $currentRow && $currentRow->hasChildNodes()) {
       $cells  = $currentRow->childNodes;
       for ($cellIndex = 0, $length = $cells->length; $cellIndex < $length; $cellIndex++) {
           $tableArray[$rowIndex][$cellIndex] = $cells->item($cellIndex)->nodeValue;
       }
   }
}

Đây là một cách dùng DOM để loop qua một table đơn giản
